问题如下：

http://stackoverflow.com/questions/19889145/setting-up-intellij-12-idea-with-java-1-7-and-resolve-java-system-java-compile

1. IntelliJ 12 CE downloaded and installed
2. Latest Java 1.7 downloaded and installed
3. JDK was setup to make and run the project

I faced the following strange error

Error: java: System Java Compiler was not found in classpath

The solution that fixed my problem was as follows:

In:

Project Settings > Compiler > Java Compiler

I changed the drop down Use compiler from Javac to Eclipse!

Non of the other solutions I found on the web was helpful. Hope this helps you my unknown fellow reader.

IMPORTANT: THIS HAD NOTHING TO DO WITH MY JAVA_HOME AS IT WAS SET CORRECTLY.
