Hi, how are you calling Maven? And which version of Maven do you use?
Furthermore I've got the impressions that those modules belong together ? Kind regards Karl Heinz On 8/3/16 8:10 PM, Thiebaud, Christophe wrote:
Hi All, The title says it all. Any suggestions how to overcome this issue ? Explanation below. Let the projects be: ‘parent’ : the parent pom of the ‘lib’ library just below ‘lib’ : the library ‘app’ : the application dependent on ‘lib’ through a version range. (all three minimalistic sample projects here: https://github.com/iroif) [cid:image001.png@01D1EDA2.91747B70] Here is what happens during time, when versions are bumped and projects are deployed to remote repo: day 0 ‘parent’ 0.0.1-SNAPSHOT is deployed to remote repo ‘lib’ 0.0.1-SNAPSHOT is deployed to remote repo ‘app’ builds OK day 1 ‘parent’ 0.0.1-SNAPSHOT is still on remote repo ‘parent’ 0.0.2-SNAPSHOT is deployed to remote repo ‘lib’ 0.0.1-SNAPSHOT is still on remote repo ‘app’ builds OK day 2 ‘parent’ 0.0.1-SNAPSHOT is still on remote repo ‘parent’ 0.0.2-SNAPSHOT is still on remote repo ‘lib’ 0.0.1-SNAPSHOT is still on remote repo ‘lib’ 0.0.2-SNAPSHOT is deployed to remote repo ‘app’ builds OK day 3 ‘parent’ 0.0.1-SNAPSHOT is automatically evicted from remote repo by some rule ‘parent’ 0.0.2-SNAPSHOT is still on remote repo ‘lib’ 0.0.1-SNAPSHOT is still on remote repo ‘lib’ 0.0.2-SNAPSHOT is still on remote repo ‘app’ build FAILS this is because maven tries to build the pom for ‘lib’ 0.0.1-SNAPSHOT and fails as ‘parent’ 0.0.1-SNAPSHOT is not available anymore. However, IMHO, the build of ‘app’ should not fail as there is another valid dependency resolution : ‘lib’ 0.0.2-SNAPSHOT with ‘parent’ 0.0.2-SNAPSHOT. In fact, when the relationship between parent and lib is a dependency (and not a parent-child relationship), the build of ‘app’ succeeds, even when transitive dependency to ‘parent’ 0.0.1-SNAPSHOT cannot be resolved. Note that ‘app’ build is successful again, when on day 4, ‘lib’ 0.0.1-SNAPSHOT is in turn evicted: day 4 ‘parent’ 0.0.2-SNAPSHOT is still on remote repo ‘lib’ 0.0.1-SNAPSHOT is automatically evicted from remote repo by some rule ‘lib’ 0.0.2-SNAPSHOT is still on remote repo ‘app’ build resumes OK Any suggestions how to overcome this issue ? We have builds failing every other day in our build farm for this reason. Thanks! Christophe PS. The content of this mail is duplicated here : https://github.com/iroif/iroif-parent
