managing multiple versions of JDK: invalid source release error

Question

I have jdk 1.6 and 1.7 installed.

I have updated my JAVA_HOME variable to

C:\\Program Files\\Java\\jdk1.6.0_24;C:\\Program Files\\Java\\jdk1.7.0
         


        

Answer 1

Your "javac -version" test shows that you are using javac 1.6. Then you are trying to build for 1.7 which is a future version that is unknown to the 1.6 compiler. I would do as some comments suggests and only define one JDK for a given project.
