No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

Question

I\'m compiling a project in Eclipse using m2eclipse. I set the JDK path in Eclipse like this:

Windows-->preferences-->installed jres--> jdk1.7.xx  p         


        

Answer 1

I tried all of the above, however, still getting the same error message.

In my case an actual JRE was incorrectly used as JRE System Library in the project-specific build path which was obviously overriding all those other settings discussed here.

If that is so in your case try the following:

1. Open the project-specific libraries of the Java Build Path: Right-click "Project > Build Path > Configure Build Path..." and select "Libraries" tab.
2. Select the "JRE System Library" entry and hit "Remove".
3. Hit "Add Library...".
4. A wizard pops up. Select "JRE System Library" and hit "Next >".
5. Now select the correct JDK (in my case "Workspace default JRE", which I configured using a JDK).
6. Close wizard by hitting "Finish".
7. Close "Properties" dialog by hitting "OK".
