Hello,
Good day. I have a maven project having the maven compiler plugin 2.5.1 for compiling the source during the build. When the JAVA_HOME variable points to JDK 8 installation directory (C:\DevEnv\ProgramFiles\Java\jdk1.8.0_20), im getting the error message Unable to locate the Javac Compiler in C:\DevEnv\ProgramFiles\Java\jdk1.8.0_20..\lib\tools.jar . The same runs with the Java 7 without any problem.

Observations :
when debugged, it ended up in the file JavacCompiler.java of artifact plexus-compiler-javac. The line System.getProperty( "java.home" ) in the compile process outputs differently for Java 8 and Java 7
For Java 7 - C:\DevEnv\ProgramFiles\Java\jdk1.7.0_80\jre
For Java 8 - C:\DevEnv\ProgramFiles\Java\jdk1.8.0_20

can you provide a fix to this ?
