IntelliJ: Fatal error compiling: invalid target release: 1.8

Question

I\'m running a Java Maven project on IntelliJ, and I make sure that this project will be compiled by Java 1.8.

I set JRE to version 8 in Run/Debug Configuration

Answer 1

• Make sure JAVA_HOME is set to JDK7 or JRE7. This is explained in the following link
  

• Make sure that you open a new shell an run intellij

• If this doesnt work, look at at the idea.bat file which is used to run intellij - make sure it uses jdk7/jre7
• Make sure the JDKs are defined properly in your project. Look at this link for more information.
• Make sure that the source is defined as 1.7 at maven

The above 4 steps always helped me to troubleshoot such issues.
