Similar problem like one posted on invalid target release: 1.7 but after following the blog my problem is still unresolved.
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hm_app: Fatal error compiling: invalid target release: 1.8 -> [Help 1]
abt java & mvn
C:\mvn>echo %MAVEN_HOME% yields
You have set your
%JAVA_HOME to jdk 1.7, but you are trying to compile using 1.8. Install jdk 1.8 and make sure your
%JAVA_HOME points to that or drop the target release to 1.7.

The target release refers to the jdk version.
