The pom.xml declare JUnit with the scope "compile". It's may be "test", else the project inject JUnit.
I suggest to replace :
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8</version>
<scope>compile</scope>
</dependency>
to
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8</version>
<scope>test</scope>
</dependency>
