So today it's the Sprint4 release. If you need an older version which is compliant to your sprint release you have to manually pick the then valid plugin from the repository: <a href="https://oss.sonatype.org/content/repositories/snapshots/com/axonivy/ivy/ci/project-build-plugin/6.1.0-SNAPSHOT/">https://oss.sonatype.org/content/repositories/snapshots/com/axonivy/ivy/ci/project-build-plugin/6.1.0-SNAPSHOT/</a></p>Reguel WermelingerTue, 16 Feb 2016 12:49:21 -0500https://answers.axonivy.com/questions/1660/project-build-plugin-6-1-snapshot-failed-to-build-ivy-project-6-1-due-to-source-level-java-1-8/1661
