That's standard practice for OSGi bundles. The https://github.com/apache/commons-compress/pull/26 changes look suboptimal because they set the same initial version for each exported package, but that's correct as a way to start doing that. The "baseline" goal of the Apache Felix maven-bundle-plugin can then be used to automatically recommend changes to those version numbers to implement semantic versioning *at the java package level* which is the way OSGi handles this. We're using this extensively in Apache Sling, where we release a large number of bundles each with their own package-level version numbers which evolve independently from the bundle version. It works well once it's setup, which is what that pull/26 does AFAICS. Here's example output from that plugin building [1] after adding a method to a class in the o.a.s.distribution package: [INFO] Baseline Report - Generated by Apache Felix Maven Bundle Plugin on 2017-06-07T08:54Z based on Bnd - see http://www.aqute.biz/Bnd/Bnd [INFO] Comparing bundle org.apache.sling.distribution.api version 0.3.1-SNAPSHOT to version 0.3.0 [INFO] [INFO] PACKAGE_NAME DELTA CUR_VER BASE_VER REC_VER WARNINGS [INFO] = ================================================== ========== ========== ========== ========== ========== [INFO] * org.apache.sling.distribution minor 0.3.0 0.3.0 0.4.0 Version increase required [INFO] < interface org.apache.sling.distribution.Distributor [INFO] + method doNothing() [INFO] + access abstract [INFO] ----------------------------------------------------------------------------------------------------------- [INFO] org.apache.sling.distribution.event unchanged 0.1.1 0.1.1 0.1.1 - [INFO] ----------------------------------------------------------------------------------------------------------- [INFO] org.apache.sling.distribution.transport unchanged 0.1.0 0.1.0 0.1.0 - [INFO] ----------------------------------------------------------------------------------------------------------- [ERROR] org.apache.sling.distribution: Version increase required; detected 0.3.0, suggested 0.4.0 [INFO] Baseline analysis complete, 1 error(s), 0 warning(s) HTH, -Bertrand [1] https://svn.apache.org/repos/asf/sling/trunk/contrib/extensions/distribution/api --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
