Creates jira release version for a train iteration if not present. Creates release tickets in Jira and GitHub if not present. Added pre-release verification that the release ticket is present and all other tickets are closed. Allow singular ticket and release version creation. Add integration tests using WireMock. Add command to self-assign release tickets.
Added CLI commands:
* jira releasetickets
* jira create releasetickets
* jira self-assign releasetickets
* jira create releaseversions
* github tickets
* github releasetickets
* github create releaseversions
* github create releasetickets
Original pull request: #14.
Introduced properties for GPG plugin and forward them to the execution of the release build. Public release versions now trigger the "central" profile being used which will enable the Nexus repository distribution.
Renamed GitCommands.checkout(…) to update(…). Made sure that project release build execution now also authenticates with Artifactory beforehand.
Switched to Apache Maven Invoker for running Maven on the projects.
Added JGraphT to correctly sort dependencies in topological order.
Upgraded to Spring Boot 1.3.2, Lombok 1.16.6, jGit 4.2.0. Upgraded to Spring Plugin 1.3 to benefit from lazy exception creation using lambdas. Added Lombok configuration to throw IllegalArgumentException on null checks.
