Any Java library to get call graph for a whole Java program and AST for each single file?

Question

I am trying to do some style-check/translation work for Java programs.

First I would like a library (preferably in Java) so I can use it in my program. Second I expect it can do the following:

• scan a whole program (multiple source files)
• provide APIs to access AST for single files
• provide APIs to access call graph, e.g. know all references of a variable, all callers of a method, etc.

In limited time, I briefly examined several tools, such as eclipse, pmd, antlr, soot:

• PMD and ANTLR: lexers/parsers, they are able to get ASTs, but no call graphs since they do not process multiple files
• Eclipse: it seems they provide APIs but only usable within its plugin framework, or binded with its RCP (does not serve as a common use library used in a stand-alone program)
• Soot: seems very close to my requirements. I am reading documents about it.

Correct me if I have misunderstanding for the above.

Answer 1

It is should be possible to use Eclipse Java compiler and its data structures as a library without RCP, etc. You may want to explore how eclipsec.exe handles this feat. That's the Eclipse equivalent to javac.exe for cases where a command-line compilation is desired.
