Change the JRE / JDK in Eclipse on Mac OS X and access the sources
Sometimes it happen that we have to change or add the JDK/JRE version used by eclipse and/or we want to access the correct source code of the JDK.
Here the step by step procedure under OS X:
- Open File -> Preferences
- Search for the Installed JRE (currently the 1.8.0_73) and click ‘Add…’
If you installed the SDK using the installer it should be in:
Choose the src.zip file from the directory containing the JDK
The change is effective only for the new projects, if you want to change the JDK/JRE for an existing project:
- Click with the right button on the project and choose ‘Properties’. Search for ‘Java Build Path’ and select the JRE under Libraries. Click te ‘Edit’ button.
- Choose the new JRE
- (Optional) Restart Eclipse
Without a restarting if you try to call the JRE sources Eclipse will throw an error
