test suite fails

[rogers0]

I packaged this library into Debian, and it seems that there're two failure when testing.
Have you ever met this kind of issue?

error log:

you can check the full build log on:
http://debomatic-amd64.debian.net/distribution#unstable/uber-pom/1.0.3-3/buildlog
(need to chick "view the whole file" on the top right of the page)

autopkgtest log:
http://debomatic-amd64.debian.net/distribution#unstable/uber-pom/1.0.3-3/autopkgtest
(the result is false pass, you can see the error in the middle of the log)

what is the version of maven?
I found in log that maven 3.6.3, will check

under ubuntu 20.04 build works well, I will try to build under debian 10.7.0

[rogers0]

I triggered a build for ubuntu 20.04:

• http://debomatic-amd64.debian.net/distribution#focal/uber-pom/1.0.3-3~ubuntu20.04/buildlog

Yes, built well, but that's because I set to ignore the errors.
The log still shows the same error:

[INFO] Results:
[INFO] 
[ERROR] Errors: 
[ERROR]   UPomMojoConfigTest.testDefaultConfig:62->init:36 » NullPointer
[ERROR]   UPomMojoConfigTest.testNonDefaultConfig:82->init:36 » NullPointer

I have installed Debian 10.7.0 under virtual box, cloned the project and build it, everything built ok.. looks like something breaks work of org.apache.maven.plugin-testing:maven-plugin-testing-harness:2.1 during build process in your case and it can't correctly init its internal objects, looks like that it can't find ProjectBuilder through lookup
and just building of the plugin works well in that environment?

looks like something breaks work of org.apache.maven.plugin-testing:maven-plugin-testing-harness:2.1

Thanks for identifying this!
Yes, the root cause is maven cannot find maven-plugin-testing-harness, even I already installed it.
I'll dig more about it.

just building of the plugin works well in that environment?

build without test seems working fine, so far.

@rogers0 any news? may be you need some help?
