Patch-diff-report-tool: shorten file names is not doing anything

[rnveach]

https://github.com/checkstyle/contribution/blob/master/patch-diff-report-tool/src/main/java/com/github/checkstyle/site/SiteGenerator.java#L219

Example:
https://checkstyle-diff-reports.s3.us-east-2.amazonaws.com/7e9dba3_2024170824/reports/diff/checkstyle/index.html#Violations

/home/runner/work/checkstyle/checkstyle/.ci-temp/contribution/checkstyle-tester/repositories/checkstyle/src/test/resources/com/puppycrawl/tools/checkstyle/checks/coding/fallthrough/InputFallThrough4.java

Example from my launch script:

src/test/resources-noncompilable/com/puppycrawl/tools/checkstyle/treewalker/InputTreeWalkerSkipParsingExceptionConfigSeverityIgnore.java

My launch scripts don't have this issue but I don't remember how it was resolved. It could be because they are running checkstyle directly and groovy is still calling the maven plugin.

File names in report are shortened at

contribution/patch-diff-report-tool/src/main/java/com/github/checkstyle/site/SiteGenerator.java

Line 174 in eed618f

filename = refFilesPath.relativize(Paths.get(filename)).toString();

.

I assume our GH action isn't working with this, while the diff scripts are, is because of the maven plugin and files have to be copied to a different location to be run on. The diff scripts run CS directly on the folder they are cloned from.

Also this is not very well documented effect at https://github.com/checkstyle/contribution/tree/master/patch-diff-report-tool
