Preparing Eclipse
In this section, you will verify that Eclipse is properly set up for Java development.
The following is assumed:
-
You are starting with a new Eclipse installation with default settings.
-
You are familiar with the basic Eclipse workbench mechanisms, such as views and perspectives.
If you're not familiar with the basic workbench mechanisms, please see the Getting Started chapter of the Workbench User Guide.
Verifying JRE installation and classpath variables
-
If you still see the Eclipse Welcome page, click the arrow icon to begin using Eclipse.
-
Select the menu item Window > Preferences to open the workbench preferences.
-
Select Java > Installed JREs in the tree pane on the left to
display the Installed Java Runtime Environments preference page. Confirm
that a JRE has been detected. By default, the JRE used to run the workbench will be used to build and run
Java programs. It should appear with a checkmark in the list of installed JREs. We recommend that you
use a Java SDK instead of a JRE. An SDK is designed for development and contains the source code for the
Java library, easing debugging. Additional SDKs can be added by searching the hard drive for installed
SDKs. To do so, simply click the Search button and specify a root folder for the search.
-
Select General > Workspace in the tree pane to display the Workspace preference page. Confirm that the Build automatically option is checked.
-
Select Java > Build Path in the tree pane to display the Build Path preference page. Confirm that Source and output folder is set to Project.
-
Select Java > Editor in the tree pane to display the Java Editor preference page.
Confirm that option Report problems as you type is checked.
-
Click on OK to save the preferences.
