The output from mvn -version

Maven home: /opt/maven

Default locale: de_DE, platform encoding: UTF-8
OS name: "linux", version: "4.2.2-1-arch", arch: "amd64", family: "unix"
Java JDK (archlinux-java get
) setting:
java-8-jdk
Java compiler version (javac -version
):
javac 1.8.0_60
I also tried to add:
<verbose>true</verbose>
<fork>true</fork>
<executable>/usr/lib/jvm/java-8-jdk/bin/javac</executable>
<compilerVersion>1.8</compilerVersion>
to the configuration
element of the maven-compiler-plugin

What is problem for the above error and how can I solve it?
