My environment is Windows 7 64bit with Eclipse [Kepler SR1] and Maven. I have to run a Maven `install` to deploy a code change, but this error is showing in the console:

> 
> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project mrpapp: Compilation failure  
> 
> [ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

but I definitely *am* running a JDK and not a JRE. I double-checked my `$JAVA_HOME` (`C:\Program Files (x86)\Java\jdk1.7.0_60`) and it *does* have a `javac.exe` in its `bin` directory.
