November 2024 (sonatype/nexus-public): Implemented major modernization and testing enhancements that deliver measurable business value and long-term maintainability. Key outcomes include S3 Lifecycle and Build/Runtime Environment Modernization to streamline build/runtime, dependency updates, refined exception handling, and updates to endorsed JARs and logging initialization; Groovy-to-Java migration in nexus-rapture with new Java classes and tests; SAML Identity Provider testing support for Nexus Docker enabling end-to-end IdP workflow testing; and a stability-oriented patch to temporarily ignore testConcurrentGenerateAndStoreKeyPair (NEXUS-44783) to maintain CI reliability while work is in progress. Public export markers were added for release snapshots. These changes improve deployment stability, reduce maintenance burden, and accelerate future migrations.
