Information about releases is kept in .release-info.json. Sample from the test projects:
{ "tagName": "MULTI_MODULE_RELEASE-2017-04-25-135920", "modules": [ { "releaseDate": "2017-04-25T15:59:20.339+02:00[Europe/Berlin]", "releaseTag": "MULTI_MODULE_RELEASE-2017-04-25-135920", "artifact": { "groupId": "de.hilling.maven.release.testprojects.independentversions", "artifactId": "independent-versions" }, "version": { "majorVersion": 1, "minorVersion": 0 } }, { "releaseDate": "2017-04-25T15:59:20.339+02:00[Europe/Berlin]", "releaseTag": "MULTI_MODULE_RELEASE-2017-04-25-135920", "artifact": { "groupId": "de.hilling.maven.release.testprojects.independentversions", "artifactId": "core-utils" }, "version": { "majorVersion": 2, "minorVersion": 0 } }, { "releaseDate": "2017-04-25T15:59:20.339+02:00[Europe/Berlin]", "releaseTag": "MULTI_MODULE_RELEASE-2017-04-25-135920", "artifact": { "groupId": "de.hilling.maven.release.testprojects.independentversions", "artifactId": "console-app" }, "version": { "majorVersion": 3, "minorVersion": 0 } } ] }
You should not have to edit this file manually. In addition you must make sure that you do not merge .release-info.json files from a bugfix branch into your master branch.
