I'm trying to update my multimodule Maven project by right clicking the project in "Project Explorer" and selecting "Maven" -> "Update". Then I get the messeage

Could not update project NAME configuration: null argument

enter image description here

The other projects update normally whithout errors. What can I do in this case?

Edit: I'm using Eclipse Mars

  • try delete the .settings folder and .project file in the project and then reimport the project. – OPK Dec 14 '15 at 14:15
  • It doesnt solve the problem. After reimporting it I'm encountering the same problem... – thomasso Dec 14 '15 at 15:14

I had the exact same problem. The .log entries are a very good hint (location: workspace/.metadata/.log). The solution was to go into Window/Preferences then navigate to Maven/Java EE Integration. Turn off the "JPA Configurator" option.

Just had the same issue. Looking at workspace/.metadata/.log the stack trace mentioned JpaFacetDataModelProvider. Then I remember I turned off the JPA facet in my project due to some other earlier problem. Re-enabling the JPA facet made the Maven issue go away. The JPA error I had earlier didn't come back, so lucky me.

The only solution for me was to configure a new worspace. Good luck !

Same issue. If you load the "Error Log" view from "Window->Show View" you might be able to see the list of errors. Double-clicking the error will give a stack-trace with Session Data.
