Hi,
Im am writing some JUnit tests for a plugin. In order to test the
plugin, I am programmatically creating a Java project, specifying
required bundles and stuff in setUp(), and I am deleting the project in
tearDown(), in order to have a clean environment for each test.
Auto building is enabled, however, my tests fail, because building is
not yet finished, and thus, the full classpath is not yet available. If
I remove the project deletion in tearDown() all but the first test
succeed. This shows that the incomplete build causes my tests to fail.
How can I either wait for the automatic build to finish or
programatically force a build?

You may want to disable autobuild, and build explicitly, e.g.
ResourcesPlugin.getWorkspace().build(IncrementalProjectBuild er.FULL_BUILD,
null);
You can look at the JDT tests for examples of what you're trying to do. A
good starting point would be the org.eclipse.jdt.core.tests.builder project;
look for BuilderTests.java and TestingEnvironment.java. There's probably a
lot of code in there you don't need, but you should be able to find examples
of everything you do need.

Doesn't work yet. My relevant code looks like this:
public static IProject createProject(final String projectName,
final List<String> srcFolders,
final List<IProject> referencedProjects,
final Set<String> requiredBundles,
final List<String> exportedPackages,
final IProgressMonitor progressMonitor) {
try {
IProject project = null;
progressMonitor.beginTask("", 10);
progressMonitor.subTask("Creating project " + projectName);
final IWorkspace workspace = ResourcesPlugin.getWorkspace();
project = workspace.getRoot().getProject(projectName);
final IWorkspaceDescription description =
workspace.getDescription();
description.setAutoBuilding(false);
workspace.setDescription(description);
if (project.exists()) {
// Clean up any old project information.
project.delete(true, true, new SubProgressMonitor(
progressMonitor, 1));
}
final IJavaProject javaProject = JavaCore.create(project);
final IProjectDescription projectDescription =
workspace.newProjectDescription(projectName);
projectDescription.setLocation(null);
project.create(projectDescription, new SubProgressMonitor(
progressMonitor, 1));
final List<IClasspathEntry> classpathEntries =
new ArrayList<IClasspathEntry>();
if (referencedProjects.size() != 0) {
projectDescription.setReferencedProjects(referencedProjects
.toArray(new IProject[referencedProjects.size()]));
for (final IProject referencedProject : referencedProjects) {
final IClasspathEntry referencedProjectClasspathEntry =
JavaCore.newProjectEntry(referencedProject
.getFullPath());
classpathEntries.add(referencedProjectClasspathEntry);
}
}
projectDescription.setNatureIds(new String[] { JavaCore.NATURE_ID,
"org.eclipse.pde.PluginNature" });
final ICommand java = projectDescription.newCommand();
java.setBuilderName(JavaCore.BUILDER_ID);
final ICommand manifest = projectDescription.newCommand();
manifest.setBuilderName("org.eclipse.pde.ManifestBuilder");
final ICommand schema = projectDescription.newCommand();
schema.setBuilderName("org.eclipse.pde.SchemaBuilder");
projectDescription.setBuildSpec(new ICommand[] { java, manifest,
schema });
project.open(new SubProgressMonitor(progressMonitor, 1));
project.setDescription(projectDescription, new SubProgressMonitor(
progressMonitor, 1));
Collections.reverse(srcFolders);
for (final String src : srcFolders) {
final IFolder srcContainer = project.getFolder(src);
if (!srcContainer.exists()) {
srcContainer.create(false, true, new SubProgressMonitor(
progressMonitor, 1));
}
final IClasspathEntry srcClasspathEntry =
JavaCore.newSourceEntry(srcContainer.getFullPath());
classpathEntries.add(0, srcClasspathEntry);
}
classpathEntries.add(JavaCore.newContainerEntry(new Path(
"org.eclipse.jdt.launching.JRE_CONTAINER")));
classpathEntries.add(JavaCore.newContainerEntry(new Path(
"org.eclipse.pde.core.requiredPlugins")));
javaProject.setRawClasspath(classpathEntries
.toArray(new IClasspathEntry[classpathEntries.size()]),
new SubProgressMonitor(progressMonitor, 1));
javaProject.setOutputLocation(
new Path("/" + projectName + "/bin"),
new SubProgressMonitor(progressMonitor, 1));
createManifest(projectName, requiredBundles, exportedPackages,
progressMonitor, project);
createBuildProps(progressMonitor, project, srcFolders);
workspace.build(IncrementalProjectBuilder.FULL_BUILD, null);
return javaProject.getProject();
} catch (final JavaModelException e) {
Log.logError("Java Model Exception", e);
} catch (final CoreException e) {
Log.logError("Core Exception", e);
} finally {
progressMonitor.done();
}
return null;
}
What's wrong?

Fixed meanwhile.
