Compile few modules via one instance of Annotation Processor

Hi.

In case of my project I need to generate code in few modules via one instance of annotation processor. It is necessary for the reason that some time during generation I need to "take a look" in the another AST and get some data out of there. By default IDEA compile each module with it's own instance of annotation processor, and hence I couldn't access to AST from another modules. On this I have a question - is it actually possible to compile few modules via one processor in IDEA?

Thanks.
