Eclipse Luna - Project explorer is empty after importing

When I am importing or trying to create project in eclipse Luna I am getting the following error:

Errors occurred during the build. Errors running builder 'Java Builder' on project 'project-name'. loader constraint violation: loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) previously initiated loading for a different type with name "org/aspectj/runtime/internal/CFlowCounter" Errors running builder 'Maven Project Builder' on project 'project-name'. loader constraint violation: when resolving method "scala.tools.eclipse.contribution.weaving.jdt.jcompiler.BuildManagerAspect.ajc$around$scala_tools_eclipse_contribution_weaving_jdt_jcompiler_BuildManagerAspect$1$add4995(Lorg/eclipse/core/internal/events/BuildManager;Lorg/eclipse/core/resources/IProject;Lorg/aspectj/runtime/internal/AroundClosure;)Lorg/eclipse/core/resources/IResourceDelta;" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, org/eclipse/core/internal/events/BuildManager, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for resolved class, scala/tools/eclipse/contribution/weaving/jdt/jcompiler/BuildManagerAspect, have different Class objects for the type .weaving.jdt.jcompiler.BuildManagerAspect.ajc$around$scala_tools_eclipse_contribution_weaving_jdt_jcompiler_BuildManagerAspect$1$add4995(Lorg/eclipse/core/internal/events/BuildManager;Lorg/eclipse/core/resources/IProject;Lorg/aspectj/runtime/internal/AroundClosure;)Lorg/eclipse/core/resources/IResourceDelta; used in the signature Errors running builder 'Java Builder' on project 'test'. org/aspectj/runtime/internal/CFlowCounter Errors running builder 'Validation' on project 'test'. loader constraint violation: when resolving method "scala.tools.eclipse.contribution.weaving.jdt.jcompiler.BuildManagerAspect.ajc$around$scala_tools_eclipse_contribution_weaving_jdt_jcompiler_BuildManagerAspect$1$add4995(Lorg/eclipse/core/internal/events/BuildManager;Lorg/eclipse/core/resources/IProject;Lorg/aspectj/runtime/internal/AroundClosure;)Lorg/eclipse/core/resources/IResourceDelta;" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, org/eclipse/core/internal/events/BuildManager, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for resolved class, scala/tools/eclipse/contribution/weaving/jdt/jcompiler/BuildManagerAspect, have different Class objects for the type .weaving.jdt.jcompiler.BuildManagerAspect.ajc$around$scala_tools_eclipse_contribution_weaving_jdt_jcompiler_BuildManagerAspect$1$add4995(Lorg/eclipse/core/internal/events/BuildManager;Lorg/eclipse/core/resources/IProject;Lorg/aspectj/runtime/internal/AroundClosure;)Lorg/eclipse/core/resources/IResourceDelta; used in the signature

I've checked the permissions, and restarted eclipse, but nothing helped me.

Do someone know/met this error? how can I fix it?

Fixed the problem. Thanks to @kucing_terbang comment, I got to understand the source of problem is

. loader constraint violation: when resolving method "scala.tools.eclipse.contribution.weaving.jdt.jcompiler...

I've tried to install scala IDE, and the scala tools were avoiding any activty.

I simply removed the scala tools (help > installationDetails, uninstall) Create a new workspace, and the import got to work!
