Chesnay Schepler commented on FLINK-28016: ------------------------------------------ Not sure either, but I built it with Maven 3.8.6 and it works as I said it would. This is also a well known behavior, see MNG-5899. > Support Maven 3.3+ > ------------------ > > Key: FLINK-28016 > URL: https://issues.apache.org/jira/browse/FLINK-28016 > Project: Flink > Issue Type: Technical Debt > Components: Build System > Reporter: Chesnay Schepler > Assignee: Chesnay Schepler > Priority: Major > Fix For: 1.16.0 > > > We are currently de-facto limited to Maven 3.2.5 because our packaging relies > on the shade-plugin modifying the dependency tree at runtime when bundling > dependencies, which is no longer possible on Maven 3.3+. > Being locked in to such an old Maven version isn't a good state to be in, and > the contributor experience suffers as well. > I've been looking into removing this limitation by explicitly marking every > dependency that we bundle as {{optional}} in the poms, which really means > {{non-transitive}}. This ensures that the everything being bundled by one > module is not visible to other modules. Some tooling to capture developer > mistakes were also written. > Overall this is actually quite a nice change, as it makes things more > explicit and reduces inconsistencies (e.g., the dependency plugin results are > questionable if the shade-plugin didn't run!); and it already highlighted > several problems in Flink. > This change will have no effect on users or the released poms, because the > dependency-reduced poms will be generated as before and remove all modified > dependencies. -- This message was sent by Atlassian Jira (v8.20.7#820007)
