Maven test error: javac: source release 1.8 requires target release 1.8

If I run mvn -e test, I get the error:

This is my Maven pom.xml:

<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
        <rules>
            <requireJavaVersion>
                <version>1.8</version>
            </requireJavaVersion>
        </rules>
      <source>1.8</source>
      <tagret>1.8</tagret>
    </configuration>
  </plugin>
</plugins>

The output from mvn -version:

Apache Maven 3.3.3 (NON-CANONICAL_2015-07-27T12:38:38_root; 2015-07-27T11:38:38+02:00)
Maven home: /opt/maven
Java version: 1.8.0_60, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-jdk/jre
Default locale: de_DE, platform encoding: UTF-8
OS name: "linux", version: "4.2.2-1-arch", arch: "amd64", family: "unix"

Java JDK (archlinux-java get) setting:

java-8-jdk

Java compiler version (javac -version):

javac 1.8.0_60

I also tried to add:

<verbose>true</verbose>
<fork>true</fork>
<executable>/usr/lib/jvm/java-8-jdk/bin/javac</executable>
<compilerVersion>1.8</compilerVersion>

to the configuration element of the maven-compiler-plugin in the POM.

What is problem for the above error and how can I solve it?
