Re: [eclipse-dev] Problem Adding NatureIds to JavaProjects

The eclipse.platform newsgroup would be an appropriate place to ask questions like this.  This mailing list is for discussion about the implementation of Eclipse itself.  (Hint: the CoreException contains a MultiStatus, and its children will tell you what the problem is).

        Subject:        [eclipse-dev] Problem Adding NatureIds to JavaProjects

I am creating a plugin in eclipse 2.1.1 that will create a template project for developers. It will create all the directories and files needed for a simple project saving the time it takes to copy an existing project over and initializing everything. I am having problems adding a Nature Id to a project when I try to set the updated project description in the existing project
The extension point in my plugin.xml is as follows:
    name="BusConnector Nature"
The method in question is:
  public static void addNatureToProject( IProject project, String natureId ) throws CoreException
    Log.debug( "BusPlugin.addNatureToProject(" + project + ", " + natureId + ")" );
    IProject proj = project.getProject();
    Log.debug( "BusPlugin.addNatureToProject() got project '" + proj + "'" );
    // Add nature only if it is not already there
    if( !proj.hasNature(natureId) )
      Log.debug( "BusPlugin.addNatureToProject() adding nature '" + natureId + "' to " + project );
      IProjectDescription description = proj.getDescription();
      String[] currentNatures = description.getNatureIds();
      String[] newNatures = new String[currentNatures.length + 1];
      System.arraycopy( currentNatures, 0, newNatures, 0, currentNatures.length );
      newNatures[currentNatures.length] = natureId;
      description.setNatureIds( newNatures );
        StringBuffer buf = new StringBuffer("Project status:\r\n");
        buf.append(" isAccessible: ");buf.append( proj.isAccessible());buf.append( "\r\n");
        buf.append(" isDerived: ");buf.append( proj.isDerived());buf.append( "\r\n");
        buf.append(" isLinked: ");buf.append( proj.isLinked());buf.append( "\r\n");
        buf.append(" isLocal: ");buf.append( proj.isLocal(0));buf.append( "\r\n");
        buf.append(" isNatureEnabled: ");buf.append( proj.isNatureEnabled(natureId));buf.append( "\r\n");
        buf.append(" isOpen: ");buf.append( proj.isOpen());buf.append( "\r\n");
        buf.append(" isPhantom: ");buf.append( proj.isPhantom());buf.append( "\r\n");
        buf.append(" isReadOnly: ");buf.append( proj.isReadOnly());buf.append( "\r\n");
        buf.append(" isSynchronized: ");buf.append( proj.isSynchronized(0));buf.append( "\r\n");
        buf.append(" isTeamPrivateMember: ");buf.append( proj.isTeamPrivateMember());buf.append( "\r\n");
        Log.debug( buf.toString() );
        proj.setDescription( description, null );
        Log.debug( "BusPlugin.addNatureToProject() there are now "+newNatures.length+" current natures" );
      catch (CoreException e)
        Log.err("D'oh! "+e.getMessage());
      Log.debug( "BusPlugin.addNatureToProject() nature '" + natureId + "' is already associated to this project" );
And here is the log that I'm generating:
DEBUG[30524:0] main | Thu Sep 18 14:35:12 EDT 2003 | BusProject.setting nature id 'com.qwest.bus.busnature'

What am I missing / doing wrong?
Thanks in advance for any help received.
