Newbie friendliness: 48/100

Issue type: Bug
Clarity: Mostly clear
Activity status: Quiet
Tech stack: java
Domain: build-system

Research direction

Start by reproducing the failure on Windows 11 with Java 21 using mvn clean, comparing clean-plugin versions 3.5.0, 3.4.1, and 3.3.2. Trace the failure through CleanMojo.java and Cleaner.java; done means an empty target directory and its nested directories are deleted successfully in the reported environment.
