Eclipse Maven Build Error invalid target release

Question

I am using Maven for the first time (in Eclipse). I would like to include HakariCP to my project. Every time I try to build my project I get following error message:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project WindowPanel: Fatal error  compiling: invalid target release: 1.8 -> [Help 1]

Here is my pom.xml:

  </dependencies>

Thanks in advance!

EDIT: All I did was update my JDK to the latest version.

Run this from cmd: `mvn -version` and tell us what it prints. — Janez Kuhar, Aug 12 '16 at 14:12

If you have JRE set to 1.7 by default in Eclipse you need to specify 1.8 in the Run Configurations. Go to "Run > Run Configurations..." and select the Maven Build you have problem with. Then click the JRE tab and choose Execution Environment Java 1.8.

If you really need to compile it against Java 8, read this question and answer.

They provide more than one to way to force Maven to use a specific version of Java.
