Fix Maven wrapper support for snapshot distributions by gnodet · Pull Request #335 · apache/maven-wrapper (original) (raw)
The Maven wrapper scripts (only-mvnw and only-mvnw.cmd) previously failed when using snapshot distributions because they assumed the directory name inside the ZIP file would match the filename pattern. However, for snapshots:
- Filename: apache-maven-4.1.0-20250710.120440-1-bin.zip
- Directory: apache-maven-4.1.0-SNAPSHOT/
This mismatch caused the script to fail when trying to access the extracted directory.
Changes:
- Modified only-mvnw to dynamically detect the actual extracted directory by looking for the Maven executable instead of assuming the name
- Applied the same fix to only-mvnw.cmd for Windows compatibility
- Added comprehensive tests in SnapshotDistributionTest.java
- Added integration test for snapshot distribution handling
- Updated documentation to mention snapshot support
The fix maintains backward compatibility with regular releases while enabling support for Maven snapshot distributions.
