I have one project in my workspace and I can open its pom.xml with the pom editor. This pom.xml references a parent pom in a different project which is not imported into my workspace. When I press the button with the hint "Open Parent POM", the pom editor opens with the contents of the parent pom.xml (so far this is expected). But at the same time I can see that the pom.xml in the local repository gets overwritten with empty content (0 bytes). Any further action with the project in my workspace results in errors ("Project build error: Non-readable POM ...: input contained no data"). When I delete the (empty) file in the local directory and do a "Maven->Update Dependencies..." from the context menu of the project, the file is restored from the repository. I debugged into the problem and this is what I found out: The overwrite of the parent pom file is triggered from a Job that is created at {code} org.eclipse.m2e.editor.pom.MavenPomEditor.reloadMavenProjectCache() line: 1041 {code} The job is immediatly scheduled, here is a stacktrace (while logging the info message "Installing ... to ..."):
