mvn test fails because of Surefire JDK version?

Question

I am trying to run mvn test on my project. The project itself compiles and installs but man test fails with the following output:

[ERROR] Failed to execute g         


        

Answer 1

Make sure your version of Maven runtime >= JRE 1.8.

Run java -version in console to check the version, if mvn command is executed in console too. Alternatively to change maven JRE in your IDE, if maven is executed in IDE.

UnsupportedClassVersionError:

Thrown when the Java Virtual Machine attempts to read a class file and determines that the major and minor version numbers in the file are not supported.

Answer 2

It seems I hadn't updated my Maven in Eclipse (right click project -> Maven -> Update Project...) or chosen JDK 8 in Window -> Preferences -> Java -> Compiler options. With these two done everything works perfectly again :)

Answer 3

The JVM shall be explicitly set in the plugin configuration.

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
      <jvm>${env.JAVA_HOME}/bin/java</jvm>
    </configuration>
  </plugin>
