[news.eclipse.tools.emf] Re: JMerge customization

["Timothy Marc" <timothymarc@xxxxxxxxxx>]

Dear Marcelo,

okay, so here is my first question. Before, i tell you, what i planned with 
Jmerge to do:

I want to reuse the JAST from JMerge, for manual analyzation of a Java file. 
I didn't want to create Target/SourceCompilationUnit, because i didn't want 
to use the JMerge algorithm for merging. All i need is a JCompilationUnit, 
which i can traverse like i've mentioned in the snippet below within the 
for-loop. Therefore, i used the following code snippet:

final File f = new 
File("F:/TFH/SE/de.freundwendland.tfh.se.JMergeCodeGeneration/src/jmerge/importWizards/ImportWizardPage.java");
final File rules = new 
File("F:/TFH/SE/de.freundwendland.tfh.se.JMergeCodeGeneration/mergeRules.xml");
JControlModel model = new JControlModel();
ASTFacadeHelper helper = new ASTFacadeHelper();
model.initialize(helper, rules.toURI().toString());
JMerger merger = new JMerger(model);
JCompilationUnit unit = 
merger.createCompilationUnitForURI(f.toURI().toString()); //causes an 
exception
ASTJCompilationUnit junit = helper.createCompilationUnit("Test", 
unit.getContents());
for(final JNode o:junit.getChildren()){
    if(o instanceof JMethod){
        System.out.println(o.getQualifiedName());
    }
}

Nothing unusual, as i think. But the process fails with the following, nut 
interpretable error message for me:
org.eclipse.emf.common.util.WrappedException: 
org.eclipse.emf.common.util.DiagnosticException: A problem was detected 
while parsing a Java file

So, does anyone or you know, why that happens? I've introspect the related 
codeline in the createCompilationUnit... method, but didn't get it.

Thx
