# Changing the compiler settings

The AspectJ compiler honors the Java compiler settings in Eclipse and also provides some extra options.

To set the extra AspectJ compiler options select Window > Preferences > AspectJ > Compiler. Options are provided for changing the severity of AspectJ-specific problems, as well as some more compiler specific settings.

AspectJ compiler options can also be changed for an individual project. Right click on the project then select Properties > AspectJ Compiler. Click the Use project settings button to configure the settings for the project.
