求助：FeatureIDE中Munge Composer自建项目创建Java类失败

I’ve run into similar problems with the Munge composer in FeatureIDE before, here are some actionable steps to diagnose and fix your issue:

• Verify FeatureIDE Project Configuration
  Right-click your project → FeatureIDE → Configure FeatureIDE Project. Make sure:

  • The composer is explicitly set to Munge (sometimes default settings don’t carry over to new projects).
  • The output directory is set to src (this is pre-configured in the HelloWorld sample, but you might have missed it in your custom project).
  • Also, confirm your source folder is marked as a source folder: Right-click source → Build Path → Use as Source Folder. Munge won’t process files in unmarked folders.

• Check Preprocessing Triggers
  The sample project might have auto-preprocessing enabled, but custom projects often require manual triggers:

  • Right-click your project → FeatureIDE → Preprocess to run the composer manually.
  • Ensure your feature model (.featuremodel file) has the correct features selected in the Feature Model view—Munge only generates code for active features.

• Inspect Munge’s Core Settings & Logs

  • Open Window → Preferences → FeatureIDE → Composers → Munge to confirm the path to the Munge executable is correct (if you installed Munge locally, a wrong path will break execution).
  • Check the Eclipse Console view, switch to the FeatureIDE log tab. Any errors (like missing files, syntax issues in preprocessor directives, or permission problems) will show up here—this is usually the fastest way to pinpoint the root cause.

• Compare Project Structure with the Sample

  • Double-check that your source folder is in the project root directory (same as the HelloWorld sample). If you nested it inside another folder, Munge might not detect it.
  • Validate the preprocessor syntax in your source files: Make sure you’re using valid directives like #ifdef FEATURE_NAME and #endif—typos here can silently fail preprocessing.
