Affected versions

3.2.0, 3.3.2, 3.5.0

Bug description

Getting random deletion error after upgrading vom 3.2.0 to 3.5.0, using Maven 3.9.7 This is on an Azure DevOps Pipeline, so I would expect no interference!?

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:3.5.0:clean (default-clean) on project NNN: Failed to clean project: Failed to delete /agent/_work/1/s/NNN/target/html/NNN/index.html -> [Help 1]

One would expect a clearer message from the Files.delete() and IOException?

Maybe backport https://github.com/apache/maven-clean-plugin/issues/180 to 3.x? Somewhat related? https://github.com/apache/maven-clean-plugin/issues/281 - where 3.3.2 seems to be fine, and 3.4.1 not.
