Research direction

Start by reproducing the issue with the pom.xml configuration shown, on macOS Sonoma, using the Groovy Greclipse formatter. Trace how the temporary directory path is created and passed through the Groovy formatter integration; done means the temporary path remains a usable filesystem path and the Maven check completes without creating encoded directories.

Written by the indexing model from the issue text.

Description

There seems to be a path encoding issue with Groovy. In the root folder where the pom.xml is located, the following temporary directories are created:

file%3A%2Fvar%2Ffolders%2F9m%2F7lp33cd577ngz_41_806qk3m0000gn%2FT%2Fspotless-groovy9943439919469970507%2F/

Instead of /var/folders it seems to encode the slashes as %2F and colon as %2A.

Any idea what could be going on?

MacOS Sonoma 14.8.1
