IllegalArgumentException on ast.newSimpleName [message #1707510]

Trying to create annotation with AST

String value = "mypackage.MyClass.class";
TypeLiteral typeLiteral = ast.newTypeLiteral();
typeLiteral.setType(ast.newSimpleType(ast.newSimpleName(value)));

I am getting IllegalArgumentException, on
ast.newSimpleName(value)

Should I use newQualifiedName?

But how would it work if my package contains 10 names??

It's just a guess, but I would guess that the value shouldn't include
the ".class"...

Correct, Ed. Plus, you can't have dots (".") in a SimpleName. If you want a qualified name (i.e. with dots) you need to construct a QualifiedName.

Say your value is "aaa.bbb.ccc.MyClass" (as Ed notes, don't include the ".class" for a TypeLiteral, that's implied by being a TypeLiteral).

SimpleName a = ast.newSimpleName("aaa");
SimpleName b = ast.newSimpleName("bbb");
QualifiedName ab = ast.newQualifiedName(a, b);
SimpleName c = ast.newSimpleName("ccc");
QualifiedName abc = ast.newQualifiedName(ab, c);
SimpleName d = ast.newSimpleName("ddd");
QualifedName abcd = ast.newQualifiedName(abc, d);
etc.

Yes, that worked.
I created a recursive method to create nested names to support any number if names in package.

Thanks
