"File name too long" error with deep paths in JUnit reports

[strido]

When using the htmlSanityCheck Gradle plugin within a sub-project, I encounter a "File name too long" error during the generation of JUnit reports.

This issue arises because the generated report filenames incorporate both the full path to the Gradle sub-project and the deeply nested folder structure of the files being checked, exceeding some filename length limit.

Caused by: java.lang.RuntimeException: java.io.FileNotFoundException: /home/xxxxx/xxx/xxxxxxxx/xxxxxxxxxx/xxxxxxxxxxxx/xxxxxxxxxxxxxxxxxxxxx/documentation/build/test-results/htmlchecks/TEST-unit-html-_xxxx_xxxxx_xxx_xxxxxxxx_xxxxxxxxxx_xxxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxx_documentation_build_test-results_htmlchecks_xxxxxxxxxxxxxxx_xx_xxxxx_xxxxxxxx_xxx_xxxx_xxxxxxxxx_xx_xxxx_xx_xx_xxxxxxxxxxxxx_xx_xxxxxx_xxxxxxxxxxxxx_xx_xxxxxxxx_xxxxxxxxxx_xxxx.xml (File name too long)

Thanks for reaching out, @strido .

Can you send a small sample project where we can see the problem?

I'm able to reproduce the problem with this project.

I have created two folders with long names to work around limitations on how long a file should be. Our project has multiple folders with shorter names, so this is just to reproduce the problem.
