Afterwards, the editor shows the source instead of the bytecode. To open this page, right-click on a project and select Properties Java Build Path. The following screenshot shows this setting for the standard Java library. The file is typically called src.

It is also possible to add Javadoc to a library which you use. For this you need to have the Javadoc somewhere in your filesystem. Select Properties Java Build Path. The Eclipse IDE allows you to install and update software components. The Eclipse update functionality only downloads new or updated components. Installable software components are located in update sites. Update sites can be located on a web server or on the file system. If you are behind a network proxy, you have to configure your proxy via the Window Preferences General Network Connection preference setting.

Otherwise, Eclipse may not able to reach the update sites. To update your Eclipse installation, select Help Check for Updates. The system searches for updates in the configured update sites for the installed software components.

If it finds updated components, it will ask you to approve the update. From the Work with list, select or enter a URL for the update site you want to use. And not categorized items are only displayed if the grouping is disabled.

After an update or an installation of a new software component, you should restart Eclipse to make sure that the changes are applied. Eclipse contains a client which allows installing software components from the Eclipse marketplace. The advantage of this client is that you can search for components, discover popular extensions and see descriptions and ratings. Compared to the update manager, you do not have to know the URL for the software site which contains the installable software components.

Most Eclipse distributions contain the Marketplace client by default. You may need to install the Marketplace client software component into Eclipse before you can use it. You can use the Find box to search for components. Pressing the Install button starts the installation process. The marketplace client allows to install your favorite plug-ins directy. For this, go to the Eclipse Marketplace website and login with your Eclipse.

Afterwards, select the Favorites tab in the Eclipse Marketplace client and login to be able to install your favorites. Eclipse plug-ins are distributed as jar files.

If you want to use an Eclipse plug-in directly or do not know the update site for it, you can place it in the dropins folder of your Eclipse installation directory.

Eclipse monitors this directory and during a re- start of your IDE, the Eclipse update manager installs and removes plug-in based on the files contained in this directory. You should not modify the content of the Eclipse plugins directory directly.

If you want to install plug-ins, put them into the dropins folder. If you want to remove it, delete the JAR from this folder. Plug-ins are typically distributed as jar files. To add a plug-in to your Eclipse installation, put the plug-in. Eclipse should detect the new plug-in and install it for you. If you remove plug-ins from the dropins folder and restart Eclipse, these plug-ins are automatically removed from your Eclipse installation.

Eclipse allows you to export a file which describes the installed Eclipse components. During the export the user can select which components should be included into this description file. Other users can import this description file into their Eclipse installation and install the components based on this file. Select the components which should be included in your description file. To install the described components in another Eclipse installation, open the exported file with File Import Install Install Software Items from File and follow the wizard.

The wizard allows you to specify the components which should be installed. The Eclipse update manager has a component called director which allows you to install new features via the command line. You need to start this command in the command line and it assumes that you are in a directory which contains your Eclipse installation in a folder called eclipse.

The feature names which you need for this operation can be seen on the second page of the standard installation dialog of the Eclipse update manager. The behavior of the Eclipse IDE can be controlled via key value pairs stores as preference settings. Each Eclipse software component can define such perferences and use the values to configure itself.

This allows you for example to configure how long the Eclipse waits before the code completion or if the import statements in your source code should be automatically adjusted if you save your source code. Which preferences are key values stored on the file system, the Eclipse IDE allows the user to configure most of these values via the preference dialog. Select Window Preferences to open the preference dialog.

You can use the filter box to search for specific settings. Correctly configuring Eclipse to your needs can largely improve your productivity. Most of these preference settings are specific to your workspace but some are also valid for all workspaces.

In this file you enter default values for preference settings. For example, the following will setup a default type filter for the java. The following example eclipse. To identify a key for a certain preference setting you can export existing preference settings via the following approach.

The Eclipse IDE is relatively conservative configured to avoid surprises during development. Certain settings in the Eclipse IDE allow you to use it more efficiently. If you find a setting in this exercise not working for you, you can always skip that setting. There is not a single correct setting for everyone in the world. You can synchronize the currently selected Java editor with the selection in the Project Explorer or the Package Explorer view.

This gives you a clearer visibility which object you are currently editing. Eclipse can make typing more efficient by placing semicolons at the correct position in your source code. In the Preference setting select Java Editor Typing. In the Automatically insert at correct position selection enable the Semicolons checkbox.

Afterwards, you can type a semicolon in the middle of your code and Eclipse positions it at the end of the current statement. Eclipse allows you to escape text automatically if it is pasted into a String literal. Eclipse would escape the text automatically for you. Now you can paste text that should be escaped. The following code snippet shows an example for the resulting code if you paste HTML code containing a link into a string literal. You can configure Eclipse to highlight the matching brackets of a code block in the source code editor.

Before the change you would not see the enclosing brackets. Afterwards, they will be slightly highlighted. This helps to see in which block you are. By default, Eclipse determines if the currently selected file is executable and try to start that.

This is sometimes confusing. You can configure the Eclipse IDE to always start the last started program. If there are several alternatives, Eclipse suggests all available packages and the user has to select the right one. The Save Actions setting can automatically organize import statements. It adds import statements automatically if there is only one possible import and removes unused ones.

The following shows the available packages for the List class in the Organize Imports dialog. The setting in the following screenshot excludes the java. Please note that Eclipse shows in its default configuration only the packages that are used in the current workspace.

If you want to exclude standard Java packages, you have to create at least one Java project. Select that the source code should be formated and that the imports should be organized at every save action. Import statements are only automatically created if where is one valid import. If Eclipse determines more than one valid import, it will not add import statements automatically. You can also define the additional actions which are performed during save.

Eclipse can override existing method calls, in case you trigger a code completion in an existing statement. Eclipse can also try to guess the correct actual parameters for a method call. Due to Bug this setting is not usable at the moment. The Eclipse IDE is configured to give you automatic code completion suggestion only after the.

YOu can configure Eclipse to get code completion on every character. You can define how the Java compiler should react to certain common programming problems. For example, you can define that an assignment of a variable which has no effect, e. You can enable annotation-based null checks in Eclipse via the setting highlighted in the following screenshot. After enabling this setting, you can use the NonNull annotation on method parameters or variable definitions to indicate that these are not allowed to be NULL.

Eclipse has the option to perform cleanup actions on existing code. This includes the removal of trailing whitespace, the additional of missing annotations but also advanced cleanups like the conversion of code to Java 8 lambda expressions. After finishing the configuration, press OK and the Next button in the cleanup wizard to get a preview of the changes.

In this exercise you first configure the Java save actions to cleanup your code during save. Afterwards you learn how you can perform a mass cleanup of your code basis. Careful here, ensure you have committed the latest version of your code so that you can revert any automatic change you dislike. You can improve this with type filters in the preference.

Type filter allow you to ignore certain packages. Eclipse has the option to perform batch cleanup on existing code. This includes simple thinks like the removal of trailing whitespace, the additional of missing annotations but also advanced cleanups like the conversion of code to Java lambda expressions. The cleanups contain also lots of options to improve the performance of your code.

This chapter lists other useful Eclipse settings which are not directly related to Java development. It also explains how to export and import your preference settings from one workspace to another.

The Default button in this preference dialog allows you to set the default editor for a certain file extension. This edit is used by default, if you open a new file with this extension. The other configured editors can be selected if you right-click on a file and by selecting Open With.

In the sub-menu you see the available editors. The available editors depend on your Eclipse installation. Eclipse remembers the last editor used to open a file. It uses this editor again the next time you open the file. You can export your preference settings from one workspace via File Export General Preferences. Eclipse does allow you to export some preference settings separately, but for most of them you have to select the Export all flag. Similarly, you can import them again into another workspace via File Import General Preferences.

You can also configure certain preference settings on a per project basis. To do this, select your project, right-click on it and select Properties. For example, on the Java Editor Save Actions you can select the Enable project specific settings checkbox to configure the save action for the current project only. This creates a. You can add this folder to your version control system to ensure that every developer uses the same setting. You could define a template which creates the method body for you.

Eclipse allows you also to specify the settings for formatting the source code. These rules are used by Eclipse if you automatically format your source code. Press the New button to create a new set of formatting rules or press the Edit button to adjust an existing profile. You can set the code formatter specific for a project via Right-click on the project Properties.

This way you can ensure that everyone is using the same formatter while working on this project. Eclipse can generate source code automatically. In several cases comments are added to the source code. In the code tree you have the templates.

Select, for example, menu:Code [Method Body] and press the Edit button to edit this template and to remove the "todo" comment. Your Eclipse installation contains a file called eclipse. For example, the -Xmx parameter can be used to define how large the Java heap size can get. The following listing shows an example eclipse. The parameters after -vmargs configure the Java virtual machine. On a modern machine with at least 8 Gigabyte available memory assigning MB or more to the Java virtual machine is a good practice to run Eclipse faster.

You can in additional also turn of class verification in the JVM. This avoids that the JVM checks if the class data which are loaded is not corrupt or invalid. To disable this check add the -Xverify:none option option on your JVM.

Eclipse allows you to configure it via startup parameters. This requires that you start Eclipse from the command line or that you configure your launcher links to include these parameters. Enables the display of the current workspace directory in the header of the running IDE. Eclipse keeps a local history of files which have changed.

Every time an editable file is saved, the Eclipse runtime updates the local history of that file and logs the changes that have been made. This local history can then be accessed and used to revert the file changes or to compare against a previous version. Eclipse opens the History view. If you double-click on an older version of the file, the Compare view shows the differences as depicted in the following screenshot.

You can replace files based on the local history. You will create more and more projects in your development career. Therefore, the data in your workspace grows and it is hard to find the right information. The Eclipse IDE allows you to organize your project into working sets so that you can hide certain resources. On the next dialog select Resource , press the Next button. Select the projects you would like to see and give it a name. You can now filter the displayed files in the Package Explorer based on the created working set.

You can also use the working set to structure your projects in your workspace. For this, select Working Sets from the context menu of the Package Explorer view. This indicates a task for Eclipse. You find those in the Task view of Eclipse. Via double-clicking on the task, you can navigate to the corresponding code. You can open this view via Window Show View Tasks. Close the editor for the MyFirstClass class. This will start a new window which shows you the help topics for your currently installed components.

The online help is version-dependent and contains the help for all Eclipse projects of the simultaneous release. The Eclipse webpage also contains a list of relevant resources about Eclipse and Eclipse programming. You find these resources under the following link: Eclipse resources and Eclipse corner wiki. Due to the complexity and extensibility of Eclipse, you will need additional resources to help you solve your specific problems.

Fortunately, the web contains several resources which can help you with your Eclipse problems. Currently, the best places to find, ask and answer questions are the Eclipse forums and Stack Overflow. Try to stay polite with your postings, as the Eclipse community values polite behavior. The Eclipse forums offer several topic-specific forums in which you can post and answer questions. To post or to answer questions in the Eclipse forums, you need a valid user account in the Eclipse bug tracker.

Stack Overflow also requires a user account and its community is very active. Stack Overflow allows to tag questions with the relevant keyword, e. Ensure that you search the forums and mailing lists for solutions for your problem. Somebody else might has asked the same question earlier and the answer is already available. If you encounter a problem with the Eclipse IDE or think about a potential improvement for it, you should report this to the Eclipse project.

The Eclipse bug and feature tracker is using the open source Bugzilla project from Mozilla. In this system, you enter Eclipse error reports. You can also request new features or improvements of existing features.

This bug tracker can be found under Eclipse Bugzilla. Here you can search for existing bugs and review them. To participate actively in the Eclipse bug tracker, you need to create a new account. This can be done by clicking the Create a New Account link. Once you have a user account, you can login to the Eclipse bug tracker. This allows you to comment on existing bugs and report new ones.

The user data for the all Eclipse sites are the same, i. Only for the Gerrit access, different user data is used. As example you can report bugs for the Eclipse platform via the following link: Bug report for the Eclipse platform. The Eclipse Bugzilla system allows you and the Eclipse committer to enter the bug priority.

But overall, it is up to each project do decide how they handle bugs so some variation from project to project will occur. The following rules can be used as guideline. The bug blocks development or testing of the build and no workaround is known.

This is the default value for new bug reports. Implies some loss of functionality under specific circumstances, typically the correct setting unless one of the other levels fit. Please please.
