Detect compilation errors after modifying AST [message #257742]

Hi

I'm using ASTRewrite to modify the AST of a compilation unit. Before I
commit the changes I need to check whether they lead to new compilation
errors or not. I tried to create a new CompilationUnit by parsing the
modified source code and using the method getProblems() to retrieve
compilation errors. But the returned array is always empty (I guess that
is because the bindings can not be resolved).

Can anybody please help? It is quite urgent.

Thank you very much!

I think to do what you want, you need to provide your own WorkingCopyOwner.

Take a look at how refactorings are done - the refactoring operations
need to solve the same problem you are trying to solve.

Thanks for your answer. Could you point me to some example code?

Well, I would start in the org.eclipse.jdt.internal.corext.refactoring.*
packages, in the source code of org.eclipse.jdt.ui. I'm sorry I can't be
more specific - I am not very familiar with that code, I just have heard
that that's how they solved the problem there.
