# AspectJ builder

The AspectJ builder builds AspectJ programs with a compiler that creates CLASS files compatible with any standard Java Virtual Machine (JVM). The AspectJ builder can build programs incrementally as individual source files are saved.

The AspectJ compiler has various preferences in addition to those provided by the Java compiler. These can be changed either for the whole workspace or on a per project basis. To change these for the workspace go to the AspectJ compiler preference page by selecting Window > Preferences > AspectJ > Compiler .
