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

There is another possible answer to this question, and I may be the only person foolish enough to have stumbled upon this, but I think it's worth adding, since none of the other answers applied as I already had those settings correct.

When you install a JDK, the installer asks you where you want to install the files. By default, on Windows, this is something like C:\Program Files\Java\jdk1.8.0_74 (or whatever version you are installing).

It then asks you for a directory to install the JRE to, which by default is something like C:\Program Files\Java\jre1.8.0_74.

Note that one is jdk1.8.0_74 and the other is jre1.8.0_74

I was rushing things, and thinking the installer was asking me the same question twice, set both my JDK and JRE install locations to D:\devtools\jdk\jdk1.8.0_74, resulting in the installer overwriting the JDK with the JRE. This resulted in (among other things) a missing javac.exe in my JDK bin, and the same error the OP reported here in all my maven builds.
