java.lang.NullPointerException

    We have spring roo based project. When I want to update maven dependencies for this project I get An internal error occurred during: "Updating Maven Configuration". java.lang.NullPointerException at com.springsource.sts.roo.ui.internal.maven.RooProjectConfigurator.doConfigure(RooProjectConfigurator.java:56) at com.springsource.sts.roo.ui.internal.maven.RooProjectConfigurator.doConfigure(RooProjectConfigurator.java:56) at com.springsource.sts.maven.AbstractSpringProjectConfigurator.configure(AbstractSpringProjectConfigurator.java:36) at org.eclipse.m2e.core.project.configurator.AbstractLifecycleMapping.configure(AbstractLifecycleMapping.java:72) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.updateProjectConfiguration(ProjectConfigurationManager.java:302) at org.eclipse.m2e.core.internal.project.ProjectConfigurationManager.updateProjectConfiguration(ProjectConfigurationManager.java:277) at org.eclipse.m2e.core.ui.internal.UpdateConfigurationJob.runInWorkspace(UpdateConfigurationJob.java:87) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) I had looked with java decompiler (cannot find source code for RooProjectConfigurator - so not sure if it pertains to spring ide) into the file com.springsource.sts.roo.ui_2.9.1.201203221000-RELEASE.jar and found IMavenProjectFacade facade = this.projectManager.getMavenProject(parent.getGroupId(), parent.getArtifactId(), parent.getVersion()); doConfigure(facade.getMavenProject(), facade.getProject(), request, monitor); I guess facade is a null. I thought it might have something to do with parent project not being opened, but if this project is open I get also NPE. This is as well described in SO: http://stackoverflow.com/questions/10098440/spring-roo-update-maven-configuration-error
