I 've experienced this problem on Eclipse Juno, the root cause was that although some spring jars were being included by transient maven dependencies they were included in incorrect versions.

To solve the problem I 've used maven dependnecy exclusions to avoid incorrect version of transient dependencies.

I had this problem after I upgraded the JDK to a new version. I had to update the references to libraries in Project Properties/Java Build Path.

Answer 4

When importing a GWT project in Eclipse without installing "Google Plugin for Eclipse", this will occur. After installing "Google Plugin for Eclipse", this error will disappear.

Answer 5

Right click on the project folder and select "Java Build Path". Under "Java Build Path" you should be able to see libraries. Eclipse will show errors in any of those libraries. Fixing those issue will help to resolve the issue.

One more case I have had. Give the correct project path, and import it to eclipse.

Then go to Project--> Clean --> Clean all projects.
