excludedPath generated-sources leads to StringIndexOutOfBoundsException: String index out of range: -1

[Treehopper]

Summary

There are two classes inside target/generated-sources/api/src/main/java matching my ArchUnitRul that I'd like to filter.
In my multi-module project, I used this in the parent-pom as well as the sub-module pom.xml:

            <excludedPaths>
              <excludedPath>generated-sources</excludedPath>
            </excludedPaths>

But I get below error. Unfortunately, I cannot tell which of my classes causes the exception.

Type of Issue

It is a :

• bug
• request
• question regarding the documentation
