My build script for bash looks like this:

eclipse \
	-nosplash \
	-application org.eclipse.equinox.p2.publisher.FeaturesAndBundlesPublisher \
	-metadataRepository file:$PWD \
	-artifactRepository file:$PWD \
	-source $PWD \
	-publishArtifact \
	-compress
eclipse \
	-nosplash \
	-console -consolelog \
	-application org.eclipse.equinox.p2.publisher.CategoryPublisher \
	-metadataRepository file:$PWD \
	-categoryDefinition file:$PWD/category.xml \
	-categoryQualifier \
	-compress

First line publishes all plugins and features on current directory. It works well always.

Second line should have to publish categories. It worked with Luna before, But now it produces lock error(below) with Mars. May be there are other different environments.

Strange thing is the second line works sometimes, but the problem is highly reproducible.
