Description

I'm using cxf version 3.1.7 in my project. And have my wadl in maven repository. But it fails to download. Have tested that all 3.0.x versions is OK, but 3.1.0 (and 3.2.0) both fails.
Plugin is configured like this:

                    </execution>
                </executions>
            </plugin>

When it runs, it logs this:

The same run on 3.0.x version works fine.

I think we need the same fix like for the issue CXF-7067.
