Yes I know this question was asked so often.
No there is no sufficient response for this.
I read this:
http://help.eclipse.org/ganymede/topic/org.eclipse.jdt.doc.i sv/guide/jdt_api_manip.htm
My not working example is:
this.project is a java project
this.default_package is a package identifier
NullProgressMonitor monitor = new NullProgressMonitor();
IPackageFragmentRoot root = this.project.getAllPackageFragmentRoots()[0];
IPackageFragment fragment =
root.createPackageFragment(this.default_package, true, monitor);
// create a cu
ICompilationUnit cu = fragment.createCompilationUnit("test.java", "",
true, monitor);
Document document = new Document(cu.getSource());
ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setSource(cu);
// get the ast cu
CompilationUnit unit = (CompilationUnit) parser.createAST(monitor);
unit.recordModifications();
// get the ast
AST ast = unit.getAST();
// create a package
PackageDeclaration pack = ast.newPackageDeclaration();
pack.setName(ast.newName(this.default_package));
unit.setPackage(pack);
// create a type declaration
TypeDeclaration type = ast.newTypeDeclaration();
type.setName(type.getAST().newSimpleName("test"));
unit.types().add(type);
// get the edits
TextEdit edits = unit.rewrite(document,
cu.getJavaProject().getOptions(true));
edits.apply(document);
cu.getBuffer().setContents(document.get());
cu.makeConsistent(monitor);
if you believe in the example in the documentation, this should work.
Nevertheless the produced file is empty.
Thanks
Guenther

Hi,
Could I please have a statement?
What's wrong with my code please?
Is there any real clean way to produce code, or is the JDT plugin not
foreseen for use outside of eclipse or in other plugins?
Thanks for any responses
Guenther

Did you debug your code step by step to see what are the TextEdit you get?
