Maven: Fatal error compiling: invalid target release: 1.8

Sometimes this problem is related to a JAVA_HOME used by maven.

In my particular case I tried to start an install target and had an exact the subj message.
Then I just tried an mvn -version command and I realized that it uses jdk7
Then I run in a console set JAVA_HOME=C:\Java\jdk8 (my jdk path, so your own could be different)
Then typed mvn clean install test and it worked just fine at last

Good luck!

Check the java and Javac version - My Java version was 1.8.0_51

$ java -version
java version "1.8.0_51"

But javac version was pointing to old jdk 1.7.0_67

$ javac -version
javac 1.7.0_67

There are couple of thing which we should try -

Ensure that symbolic link is pointing to correct jdk. If not, remove existing link and create new one for your jdk

cd /System/Library/Frameworks/JavaVM.framework/Versions/
rm CurrentJDK
ln -s /Library/Java/JavaVirtualMachines/<jdk version>.jdk/Contents/ CurrentJDK

In /Library/Java/Extension, i had a tools.jar. I believe, this was from old jdk.

cd /Library/Java/Extensions
-rw-r--r--  1 root  admin  15286304 Jan 14  2015 tools.jar

Remove this

sudo rm -rf /Library/Java/Extensions

point 2 did the trick for me :)

Same issue here, but I was using run configurations inside Eclipse when maven kept throwing this error. Fixed by setting the right JDK version here:
