Is there a simple way to create a workspace including one (or more)
projects programmatically using the Eclipse API. By simple I mean
something like two API function calls, the first call specifying
essentially only the location for the new workspace, the second call
specifying essentially only the location of an existing project or
directory.
The reason why I'm asking this is that we would like to be able to create
a workspace with projects from one or more simple configuration files,
e.g. like it is done in Visual Studio with *.dsw and *.dsp files, and we
want to save these workspace description files within our CVS repository.

Here is an example:
(for more examples see the automated tests of the eclipse platform project.)
/**
* Creates a IJavaProject.
*/
static IJavaProject createJavaProject(String projectName, String
binFolderName) throws CoreException {
IWorkspaceRoot root= ResourcesPlugin.getWorkspace().getRoot();
IProject project= root.getProject(projectName);
if (!project.exists()) {
project.create(null);
} else {
project.refreshLocal(IResource.DEPTH_INFINITE, null);
}
if (!project.isOpen()) {
project.open(null);
}
IPath outputLocation;
if (binFolderName != null && binFolderName.length() > 0) {
IFolder binFolder= project.getFolder(binFolderName);
if (!binFolder.exists()) {
createFolder(binFolder, false, true, null);
}
outputLocation= binFolder.getFullPath();
} else {
outputLocation= project.getFullPath();
}
if (!project.hasNature(JavaCore.NATURE_ID)) {
addNatureToProject(project, JavaCore.NATURE_ID, null);
}
IJavaProject jproject= JavaCore.create(project);
jproject.setOutputLocation(outputLocation, null);
jproject.setRawClasspath(new IClasspathEntry[0], null);
return jproject;
}
private static void addNatureToProject(IProject proj, String natureId,
IProgressMonitor monitor) throws CoreException {
IProjectDescription description = proj.getDescription();
String[] prevNatures= description.getNatureIds();
String[] newNatures= new String[prevNatures.length + 1];
System.arraycopy(prevNatures, 0, newNatures, 0, prevNatures.length);
newNatures[prevNatures.length]= natureId;
description.setNatureIds(newNatures);
proj.setDescription(description, monitor);
}
/**
* Creates a folder and all parent folders if not existing.
* Project must exist.
* <code>org.eclipse.ui.dialogs.ContainerGenerator</code> is too heavy
* (creates a runnable)
*/
static void createFolder(IFolder folder, boolean force, boolean local,
IProgressMonitor monitor) throws CoreException {
if (!folder.exists()) {
IContainer parent= folder.getParent();
if (parent instanceof IFolder) {
createFolder((IFolder)parent, force, local, null);
}
folder.create(force, local, monitor);
}
}
/**
* @param project the project to delete.
* @throws CoreException
*/
static void delete(final IJavaProject jproject) throws CoreException {
IWorkspaceRunnable runnable= new IWorkspaceRunnable() {
public void run(IProgressMonitor monitor) throws CoreException {
jproject.setRawClasspath(new IClasspathEntry[0],
jproject.getProject().getFullPath(), null);
for (int i= 0; i < MAX_RETRY; i++) {
try {
IProject tmpProject = jproject.getProject();
synchronized (tmpProject) {
if (tmpProject.exists())
tmpProject.delete(true, true, null);
}
i= MAX_RETRY;
} catch (CoreException e) {
if (i == MAX_RETRY - 1) {
EntireXWorkbenchTestPlugin.log(e);
throw e;
}
try {
Thread.sleep(1000); // sleep a second
} catch (InterruptedException e1) {
}
}
}
}
};
ResourcesPlugin.getWorkspace().run(runnable, null);
}

Thank you for the information.
However, I couldn't find a sample of how to create an empty workspace
programmatically, neither in your code sample nor in one of the following
sources:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.core.te sts.resources/src/org/eclipse/core/tests/resources/IWorkspac eRootTest.java?view=co
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.core.te sts.resources/src/org/eclipse/core/tests/resources/IWorkspac eTest.java?view=co
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.ide/ src/org/eclipse/ui/internal/ide/actions/OpenWorkspaceAction. java?view=co
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.ide. application/src/org/eclipse/ui/internal/ide/application/IDEA pplication.java?view=co
Although there are a lot of samples of how to create projects
programmatically, there is no one for the actual workspace creation.
Would anybody please give me another hint.

Hi Karl,
As Eclipse use a single workspace at runtime, I think you simply need to restart Eclipse with the right option.
from http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/misc/runtime-options.html "data" option seems the right one.
Regards,
Mariot
