Clean old temporary local maven index cache dir before scan #7586

Closed mbien closed 1 month ago

mbien commented 1 month ago

When the last local maven repo scan didn't clean up properly, for example when the JVM exits during scan, subsequent scans would throw java.io.IOException: Cannot create temporary directory.

This has a fairly low probability since local index scans finish fast - saw this during debugging.

exception:

java.io.IOException: Cannot create temporary directory: /home/mbien/NetBeansProjects/netbeans/nbbuild/testuserdir/var/cache/tmp-local

how to simulate: create a tmp-local folder in your fresh cache folder, trigger initial local repo indexing, e.g by adding a dependency to a maven project.
