maven test fails if junit jar in project.xml dep

I have junit jar dep declared in my project project.xml:

<dependency>
<id>junit</id>
<version>3.8.1</version>
<properties>
<classloader>root</classloader>
</properties>
</dependency>

(I need it to compile some classes in src/java).

When I run "maven test", I get:

test:test:
[junit] Running patterntesting.plugin.aspectj.TestAjcCompiler
