Review Comment:
This uses the prebuilt function `runTreeMojo` that is also used by most
other tests in the file, which throws an Exception. I don't think this can be
more specific without changing `runTreeMojo`. Within `runTreeMojo` there are
function that throws the following exceptions:
`lookupMojo`: `Exception`
`setVariableValueToObject`: `IllegalAccessException`
`this.stubFactory.createArtifact`: `IOException`
`mojo.execute()`: `MojoFailureException` and `MojoExecutionException`
