Make sure you have the Java Development Kit (JDK) installed in your computer.
Check if you have Java 8 installed, while trying to compile with Java 7, or viceversa. In other words, check if the JDK is set to the wrong version.
Make sure the JDK is FIRST in your Path, by placing %JAVA_HOME%\bin at the beginning of your Path in your System variables.
