Answer 1

The problem is that your maven is using java 5 (as your comment says). You have to change your JAVA_HOME variable to point to jdk 6 or higher. Look at :

Error when using javac: "javac: invalid flag: -s"

Answer 2

In my case i dont have the apropiate environment variable because the project is inherited, and I had not created the variable JDK_WAS85_JDK8 = C:\Program Files\Java\jdk1.8.0_221. Usually is JAVA_HOME the variable that is set.
