🐛 Fix Docker build by switching PlantUML source to GitHub releases#1708
Merged
Conversation
The Sourceforge mirror netcologne.dl.sourceforge.net used in the Dockerfile is no longer reachable, causing the Docker-Image workflow to fail with wget exit code 4 (network failure). Switch to the official GitHub releases URL, which is reliable and always serves the latest plantuml.jar.
