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 1.8 Java™ runtime environment (JRE), you must set the compiler compliance level
of your workspace to 1.8. To do this, from the
Eclipse menu bar, select Window
> Preferences > Java > Compiler and set the Compiler
compliance level to 1.8
.
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.
