Exception in thread "Thread-7" java.lang.NoClassDefFoundError: org.eclipse.core.resources.ResourcesPlugin
Caused by: org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter$TerminatingClassNotFoundException: An error occurred while automatically activating bundle org.eclipse.core.resources (24).
Caused by: org.osgi.framework.BundleException: Exception in org.eclipse.core.resources.ResourcesPlugin.start() of bundle org.eclipse.core.resources.
Caused by: java.lang.IllegalStateException: The platform metadata area could not be written: /home/rtc/Documents/jtc/buildsystem/buildengine/eclipse/workspace/.metadata. By default the platform writes its content
under the current working directory when the platform is launched. Use the -data parameter to
specify a different content area for the platform.
Kindly suggest
