Error when using javac: “javac: invalid flag: -s”

问题

I am trying to specify another version of JDK in maven-compiler-plugin. When -target and -source parameters are set to 1.5, everything is ok. But when i try to use 1.6 JDK, maven reports an error. Has anyone faced this problem?

Error:

Failure executing javac, but could not parse the error: javac: invalid flag: -s Usage: javac where possible options include: -g Generate all debugging info -g:none Generate no debugging info

Thanks.

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

Check it with java -version on a command line.

To define your JAVA_HOME do this:

Add to your ~/.bashrc this line:

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