Plugin fails if there is a space in project directory path

[lhannest]

1. Try modifying the path of a project using this plugin like "path/to/project/directory with space in the name/project"
2. Set <quiet>false</quiet> in the AssertJ plugin
3. Rebuild mvn clean install -DskipTests=true
4. Nothing gets generated, in the output it shows that no target classes have been found
