-1 (nb) 1. FYI IDEA 2026.2.1 Preview does not support Maven 4.0.0-rc-6 [third attempt] import, it was fine on the second attempt. This IDEA version already implemented 3.10.0-rc support Ticket: https://youtrack.jetbrains.com/issue/IDEA-392211/Support-Maven-4.0.0-rc-6-import
2. The build performance is noticeably worse,than 3.9.16, I had to increase timeouts in CI as the process was just killed as too long. Reproducers: - Maven multiproject generator https://github.com/maven-turbo-reactor/maven-multiproject-generator 1m5s on 3.9 vs 1m29s on 4.0 - Maven multimodule reproducer (shared in DM with Tamas) 6s on 3.9 vs 14s on 4.0 3. Maven clean race condition of target/project-local-repo when root project has parent, submitted https://github.com/apache/maven/issues/12646 4. The resolution strategy of the "closest" version is changed, see https://github.com/apache/maven/issues/12648 On Fri, Jul 31, 2026 at 1:50 PM Sylwester Lachiewicz <[email protected]> wrote: > +1 > > czw., 30 lip 2026, 18:31 użytkownik Guillaume Nodet <[email protected]> > napisał: > > > Hi all, > > > > We solved the following issues since rc-5: > > https://github.com/apache/maven/releases/tag/maven-4.0.0-rc-6 > > > > Issues fixed since the first rc-6 attempt: > > - Fix #12583: Inverted file existence check in DefaultTransport.put() > > - Remove erroneous PathSelector optimization that skipped path > > relativization > > - Remove PathSelector include-based directory pre-filtering optimization > > - Add Apache license headers and fix NOTICE files to address ATR concerns > > - [MNG-8507] mvnup: skip dedup inside plugin <configuration> elements > > > > Issues fixed since the second rc-6 attempt: > > - Fix BOM consumer POM leaving property references unresolved (#12627) > > - Use resource filtering for mng-12534 IT plugin mavenVersion to avoid > > hardcoded versions > > > > Staging repo: > > https://repository.apache.org/content/repositories/maven-2452/ > > > > Source release: > > > > > > > https://repository.apache.org/content/repositories/maven-2452/org/apache/maven/apache-maven/4.0.0-rc-6/apache-maven-4.0.0-rc-6-src.zip > > > > Source release SHA-512: > > > > > > > 5150cb8168e62cc0bae24516f35293eaac0d099e45a2f0c8ec40a96b1cc9c384f26abe943cfa57ac9c4cf3f762ef7e413c43242106bea0ffa3d9f8a3709d431e > > > > Distribution: > > https://dist.apache.org/repos/dist/dev/maven/maven-4/4.0.0-rc-6/ > > > > Staging site: > > https://maven.apache.org/ref/4-LATEST/ > > > > Guide to testing staged releases: > > > https://maven.apache.org/guides/development/guide-testing-releases.html > > > > Vote open for at least 72 hours. > > > > [ ] +1 > > [ ] +0 > > [ ] -1 > > > > Guillaume Nodet > > >
