Hello,

I got a problem when I was trying to use the AST, here is the code,

protected CompilationUnit parse(char[] sourceArray) {
ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setSource(sourceArray);
parser.setResolveBindings(true);
return (CompilationUnit) parser.createAST(null);
}

I got the error below:
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/resources/IResource
at org.eclipse.jdt.core.dom.ASTParser.<init>(ASTParser.java:176)
at org.eclipse.jdt.core.dom.ASTParser.newParser(ASTParser.java: 125)
at Analyzer.parse(Analyzer.java:96)
at Analyzer.analyzing(Analyzer.java:55)
at API_RM.main(API_RM.java:7)

... 5 more


I have already include the JDT variable(List below) by adding the external variable and also the "org.eclipse.equinox.common_3.6.0.v20100503.jar" from ECLIPSE_HOME. Am I missing something? Why I got the problem?

Please help me out to get this done.

Thanks for your help in advance.

Regards,
Kam

You need at least org.eclipse.core.resources and org.eclipse.core.runtime.
This is needed to resolve some method signatures, but DOM/AST API themselves can be used outside of a headless Eclipse.

This means you also need org.eclipse.core.jobs.
You need to continue to do this until everything is there.
The best way to know what you need is to use a launching configuration and select org.eclipse.jdt.core as the only bundle. Then you click on "Add required bundles" and you will see all the bundles that you need.

Thank you again, Olivier
I think I know what's going on.
Although I don't know how to use the "launching configuration",
but I have tried to search jar which can solved the exception. The problems is solved temporally.

Thank you for your help.
