Set Runtime-Classpath (LaunchConfiguration) programmatically [message #285187]

Hallo,
myPlugin sets for certain javaprojects a nature (extends from
IProjectNature). Now I want to add new runtime-classpath for every
launchconfiguration for this projects. (I want do this programmatically
inside my plugin when I set the nature...).

First I tried the Extension:
Code:

<extension
point="org.eclipse.jdt.launching.runtimeClasspathEntries">
<runtimeClasspathEntry
class="MyPathEntry"
id="MyPathEntryID">
</runtimeClasspathEntry>
</extension>

but it did not work.

Then I tried the Extension:
Code:

<extension
point="org.eclipse.jdt.launching.classpathProviders">
<classpathProvider
class="MyClasspathProvider"
id="MyClasspathProviderID">
</classpathProvider>
</extension>

but my class MyClasspathProvider is never executed.

Even if I walk through all launchconfigurations when i set my nature:
Code:

ILaunchManager manager = DebugPlugin.getDefault().getLaunchManager();
ILaunchConfiguration[] lcs = manager.getLaunchConfigurations();
for (int i = 0; i < lcs.length; i++) {
ILaunchConfiguration configuration = lcs[i];
ILaunchConfigurationWorkingCopy wc =
configuration.getWorkingCopy();
if(wc.getAttribute("org.eclipse.debug.ui.private", false)) {
continue;
}
wc.setAttribute("ATTR_CLASSPATH_PROVIDER",
"MyClasspathProviderID");
wc.doSave();

}

and I set the attribute "ATTR_CLASSPATH_PROVIDER" with my provider id
"MyClasspathProviderID", like described in the documentation of this
Extension-Point nothing happens...

What do I wrong?
Can someone help me, please?

Your classpath provider will be asked to compute an unresolved classpath for
your launch configs when they are launched, and to resolve the classpath
they compute. See JavaRuntime.computeUnresolvedRuntimeClasspath(...).

Thanks,
since I use IJavaLaunchConfigurationConstants.ATTR_CLASSPATH_PROVIDER
instead of "ATTR_CLASSPATH_PROVIDER", it works...of course.
bye

I also want to do the same "myPlugin sets for certain javaprojects a nature (extends from IProjectNature). Now I want to add new runtime-classpath for every launchconfiguration for this projects. (I want do this programmatically inside my plugin when I set the nature...)."

But I could not fined details on org.eclipse.jdt.launching.classpathProviders i.e. how to implement MyClasspathProvider and what to return for computeUnresolvedClasspath() and resolveClasspath() methods? Can someone provide me with explanation of these methods?

Thank you.
