Error found when trying to compile code

Question

When I try to maven run the test code, this error pops up:

I run Maven from Eclipse and have set a JDK in Preference > Java > Installed JREs but I still get that error.

What are the solutions to it?

A little more context would help. How are you running Maven? How did you "configure the JDK"? — André Stannek, May 21 '14 at 09:32

Are you running this through an IDE, or through the console? — carlspring, May 21 '14 at 09:44

You haven't set your JAVA_HOME variable correctly, or $JAVA_HOME/bin (%JAVA_HOME%\bin) is not on your PATH variable (I would advise you put this at the beginning of the PATH environment variable).

I've set the environment variables for java_home and path. – user3659013 May 21 '14 at 09:43
What are they set to? Please, mention this in your question. Also, what do you get when you execute `mvn --version`? – carlspring May 21 '14 at 09:44

Do you have you JAVA_HOME in the path? – Uwe Allner May 21 '14 at 09:51
You need to have `JAVA_HOME/bin` on your `PATH`. – carlspring May 21 '14 at 10:01
And don't put these as answers to the comments, add them as an edit in your question. – carlspring May 21 '14 at 10:03

It's not enough to set a JDK in "installed JREs" when you run Maven from Eclipse. Eclipse itself also has to run in a JDK.

To make sure of that, edit the eclipse.ini in your Eclipse folder. Add somtehing like

-vm
C:/Program Files/Java/jdk1.7.0_51/bin/javaw.exe

of course with the right path to your JDK.
