- switch from Sonatype Aether to Eclipse Aether ( contains a package change in several Maven APIs)
- support of JSR330 in plugins ( javax.inject)
Change the prerequisite to 3.1.1. In general we would like to say "Plugins are Maven 3.x-compatible", which would mean its value should be 3.1.0. However, if your plugin depends on asm, you'll get the wrong version with Maven 3.1.0, hence to prevent this, the prerequisite should be set to 3.1.1.
- drop maven-artifact-transfer. It sole purpose was to make it possible for plugins to support both Sonatype Aether (Maven 3.0.x) and Eclipse Aether (Maven 3.1.0+ and rebranded to Maven Artifact Resolver for Maven 3.5.0+). The extra abstract layer of maven-artifact-transfer only adds complexity and a library that must be maintained. Once everything depends on Maven 3.1.0 we can archive maven-artifact-transfer.
