AutoEnhancer classpath, or classloader issue. Fails validation.

Should the facet gatekeep turning on the auto enhancing when in facet mode.

sdk = GaeSdk.findSdkFor(javaProject); is finding, and this is wrong.

/Users/branflake2267/.m2/repository/com/google/appengine/appengine-api-1.0-sdk/1.9.18/appengine-api-1.0-sdk-1.9.18.jar, /Users/branflake2267/.m2/repository/com/google/appengine/appengine-api-1.0-sdk/1.9.18/appengine-api-1.0-sdk-1.9.18.jar,

It appears the issue exists in GaeSdk.getInstallationPath() when m2e is providing the library, it has the wrong base path for the java sdk .

[branflake2267]

GaeSdkInstaller is installing zip by unzipping and adding it to the list. "gaeSdk" extension query not pulling it up.

Fixed library path, but now, the enhancer isn't getting the tools lib loaded in the classpath. Tracking that down now. Trying to figure out how the bridge is adding the tools api jar to classpath for enhancer.

workaround for maven lib path.

@Override
    public IPath getInstallationPath() {
      try {
        IPath fragmentRootPath = null;
        IPath installPath = null;
        // Check for a type that lives appengine-api-*.jar
        IType gaeMarkerType = javaProject.findType(GAE_MARKER_TYPE);
        if (gaeMarkerType != null) {
          IPackageFragmentRoot packageFragmentRoot =
              (IPackageFragmentRoot) gaeMarkerType.getAncestor(IJavaElement.PACKAGE_FRAGMENT_ROOT);
          fragmentRootPath = packageFragmentRoot.getPath();

          // Used for maven path, this may not be the best method (might be considered to be a workaround)
          // See: GaeSdkInstaller.mavenRepositorySdkPath(...)
          if (fragmentRootPath.segmentCount() > 3 && MavenUtils.hasMavenNature(javaProject.getProject())) {
            String version = fragmentRootPath.removeLastSegments(1).removeFirstSegments(fragmentRootPath.segments().length - 2).toPortableString();
            String sdkPath = String.format("appengine-java-sdk/%s/appengine-java-sdk/appengine-java-sdk-%s", version, version); // from GaeSdkInstaller
            installPath = fragmentRootPath.removeLastSegments(3).addTrailingSeparator().append(sdkPath);

            System.out.println("~~~~ installPath=" + installPath);
          } else if (fragmentRootPath.segmentCount() > 1
              && (fragmentRootPath.removeLastSegments(1).addTrailingSeparator().toPortableString()
                  .endsWith(SDK_LIB_USER_DIR_PORTABLE_SUBPATH) || fragmentRootPath
                  .removeLastSegments(1).addTrailingSeparator().toPortableString()
                  .endsWith(SDK_LIB_IMPL_DIR_PORTABLE_SUBPATH))) {

                    .getAncestor(IJavaElement.PACKAGE_FRAGMENT_ROOT);
            fragmentRootPath = packageFragmentRoot.getPath();
            if (fragmentRootPath.segmentCount() > 1

Wahoo, fixed in app. Going to pull and test.

EnhancerJob

 @Override
  public IStatus runInWorkspace(IProgressMonitor monitor) throws CoreException {

    List<String> classpath = buildClasspath(javaProject);

    // Workaround, when using maven project, the tools api jar isn't in rumtime classpath
    if (sdk != null && MavenUtils.hasMavenNature(javaProject.getProject())) {
      IPath toolApiJarPath = sdk.getInstallationPath().append(GaeSdk.APPENGINE_TOOLS_API_JAR_PATH);
      classpath.add(toolApiJarPath.toPortableString());
    }
