Setting the compiler compliance level
The Java™ runtime environment (JRE) of both
your Eclipse workspace and your intended runtime environment must be
the same. For example, if you are developing a ZIETrans rich client plug-in to run on an
Eclipse environment that is running a 17 Java™ runtime
environment (JRE), you must set the compiler compliance level of your workspace to 17. To do
this, from the
Eclipse menu bar, select Window > Preferences > Java >
Compiler and set the Compiler compliance level to
17.
If you have other Java™ or plug-in projects in your workspace that require other compliance levels, you can set the compiler compliance level for individual Java™ or plug-in projects. To do this, right-click on the project and select Properties. In the Properties panel select Java Compiler on the left. Then select the Enable project specific settings box and set the Compiler compliance level to the appropriate level.
