Error using javac: "javac: invalid flag: -s"

Question

I am trying to specify a different version of the JDK in the maven-compiler-plugin . If the -source and -source set to 1.5, everything is fine. But when I try to use 1.6 JDK, maven reports an error. Has anyone encountered this issue?

Error:

Failed to execute javac, but could not parse the error: javac: invalid flag: -s Usage: javac where options are possible: -g Generate all debug information -g: none Do not create debug information

Thanks.

If you use flag 1.6, your JAVA_HOME should point to JDK 1.6.

Verify this using java -version on the command line.

To define your JAVA_HOME, follow these steps:

Add this line to your ~/.bashrc :

 export JAVA_HOME=$(/usr/libexec/java_home)
