Parse .java file and analyze its AST

Question

Im looking for a parser that could parse .java file and create some object, which should held informations about this file's methods, attributes. classes, interfaces, methods parameters and annotations.

Do you know any?

I found https://code.google.com/p/javaparser/, but im not sure if it can handle annotations, which are important for me..

any advice?

thanks

If you're not sure if it can handle annotations, it would be preferable it you did some more research prior to posting here... — jlordo

There are many parsers available for Java code, each with its own intended purpose and advantages/disadvantages. Based on the amount of detail in the original post, 1) there's no way to determine what would be appropriate for your case and 2) these parsers are highly non-trivial to use, and there's no indication that you've researched this space enough to be able to actually use one that gets suggested. — Sam Harwell

Why not use the standard Java Compiler API? I know it was discussed within the latest Java Magazine issue -- for some source samples, see here.

This + Java Annotation Processors should be enough for all code generation needs.

You could use the Java Grammar (http://docs.oracle.com/javase/specs/jls/se7/html/jls-18.html) and use a parser generator (for example YACC) or Scala ParserCombinators to generate an AST. In this grammar, annotations are contained.

I am using JavaParser to parse java Code, and yes - it can handle annotations, for example - getting method's annotations:

List<AnnotationExpr> annotations = method.getAnnotations();

Adding annotations (by name) to a method:

annotations.add(new NormalAnnotationExpr( ASTHelper.createNameExpr("Override"), null));
