Description

First deliverable shall

• be designed as part of a more complex provisioning system
  • provide APIs to be later used by that system
• implement Delta Management requirements from MNG-3966

When started with a pointer to a maven instance, it shall:

• find maven-distribution-xx.jar in ./lib to use for current version
• retrieve all existing versions of the "same family" (a'la 3.0.xx) for org.apache.maven:maven-distribution:3.0.xx
• let user supply a version to up / down grade to
• calculate, using Mercury APIs
  • runtime scoped classpath for "current" pom.xml
  • runtime scoped classpath for selected version's pom.xml
  • retrieve the binary diff to local repo
• make ./lib reflect the "new" runtime classpath
  • remove replaced binaries
  • copy in missing binaries
