Maven Install: "Annotations are not supported in -source 1.3"

Question

When running mvn install on my project, i see it fail due to the following errors:

C:\Repositories\blah\src\test\java\com\xxx\qm\testrunner\test\ATest.java:[11,5] annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
    @Test

C:\Repositories\blah\src\test\java\com\xxx\qm\common\test\BTest.java:[11,5] annotations are not supported in -source 1.3
(use -source 5 or higher to enable annotations)
    @Test

My Maven dependency includes jUnit 4.8, however and has no reference to 1.3 anything.

What would cause these errors? Please advise

You need to specify the source version of your maven project through the use of the maven-compiler-plugin. Add the following to your pom build element and set the appropriate java source and target levels.

<build>
     <defaultGoal>install</defaultGoal>
     <plugins>
          <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-compiler-plugin</artifactId>
               <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
               </configuration>
          </plugin>
      </plugins>
</build>

A shorter version:

<project>
    <properties>
        <maven.compiler.source>1.5</maven.compiler.source>
        <maven.compiler.target>1.5</maven.compiler.target>
    </properties>
