Apache Maven JAR Plugin 4.0.0-beta-2

Warning

This plugin is a Maven 4 plugin and requires Maven 4.x to run. This release introduces several key improvements, including more robust change detection, a new "attach" configuration parameter, and the ability to add the Java version to the MANIFEST.MF. Users will benefit from enhanced stability through fixes for multi-release JAR detection on Windows, improved handling of invalid Automatic-Module-Name entries, and the decoupling of test-jar skipping from the standard maven.test.skip property. Additionally, the plugin now migrates from Maven Archiver to the standard jar tool and includes logic to skip JAR creation when no files match the specified includes.

• Reformatting of #610 for reducing the amount of redundancies (#620) @desruisseaux
• Remove redundant project.build.sourceEncoding from IT POMs (#605) @gnodet
• Disable Jenkins build until Maven 4.0.0-rc-7 is installed on agents (#608) @gnodet

Apache Maven Archiver 4.0.0-beta-6

This release introduces several important bug fixes, including improved handling of negative epoch timestamps and better sanitization of invalid Automatic-Module-Name and manifest entry values. We have addressed multiple NullPointerExceptions related to manifest configurations and plugin maps to improve overall stability. Additionally, this version includes performance optimizations, such as caching model results and reducing redundant pattern compilation, alongside updated documentation regarding null-value behavior in manifest methods.

🐛 Bug Fixes

• fix: do not clamp negative epoch timestamps to DATE_MIN (#419) @gnodet
• Remove duplicate LOGGER field in MavenArchiver (#417) @ascheman
• [MJAR-595] - Clamp outputTimestamp to DATE_MIN when SOURCE_DATE_EPOCH=0 (#401) @gnodet
• fix: report invalid archiver properties (#414) @efegokdemir
• Sanitize invalid Automatic-Module-Name instead of failing (#402) @gnodet
