If I use a class inside a body=... statement the class does not get imported to the generated class.
How can I force JvmInferrer to import a class I used in a body statement?

body = '''<<Myclass>>'''

I tried the following:

members += element.toMethod("open", typeRef(void)) [
				visibility = JvmVisibility.PROTECTED
 				parameters += element.toParameter("indexPath", typeRef(String))
				body = '''
					<<java.nio.file.Paths>>
					<<org.apache.lucene.store.FSDirectory>>
					<<org.apache.lucene.index.DirectoryReader>>
			        path = Paths.get(indexPath);
			        directory = FSDirectory.open(path);
			        indexReader =  DirectoryReader.open(directory);
			        synchronized(this) {
			        	indexSearcher = null;
			        }
				'''
			]

and get this:

  protected void open(final String indexPath) {
    <<java.nio.file.Paths>>
    <<org.apache.lucene.store.FSDirectory>>
    <<org.apache.lucene.index.DirectoryReader>>
    			        path = Paths.get(indexPath);
    			        directory = FSDirectory.open(path);
    			        indexReader =  DirectoryReader.open(directory);
    			        synchronized(this) {
    			        	indexSearcher = null;
    			        }
  }

What I did wrong ?
