I want to build my code with Java 6, but use compile time checks of Java 5.
For example, I want the compiler to complain about @Override annotation for interfaces (introduced in Java 6).
Do you know how to do this?

I am not sure if this is possible.sgowd– sgowd2012-02-17 12:46:38 +00:00Commented Feb 17, 2012 at 12:46

Are you using Ant to build. If so I think then you can ask ant to compile and build using Java 6. Whereas to enable Java 5 checks right click on the project and set Java Compiler compliance to Java 5Sandeep Nair– Sandeep Nair2012-02-17 12:48:49 +00:00Commented Feb 17, 2012 at 12:48

Seems kms333 needs to use different compilers to a same project. Check once.
The JRE preference seems to be at the workspace not project level. To change the JRE, Window...Preferences. Open up the tree under 'Java'. Choose "Installed JREs". If there's only one there, you can't remove it. Click 'Add...'. Browse to the base directory of the Java installation, e.g. /usr/java/jdk1.6.0. Give the JRE a name and click OK. This adds the new JRE to the list of JREs available. To select it as the default JRE, it must be checked in the Installed JREs window.

If you are using Maven (or Ant) for building your project, then you can specify Java 6 in Maven and keep eclipse using Java 5.
