4.0.0-rc-630 Jul 2026pre-releaseDeprecated

[maven-4.0.x] Fix #12304 : replace deprecated property expressions in mvnup ( #12308 ) @gnodet

Notes

This new release candidate of Maven 4 is released to get feedback from users.
Maven 4 has restricted a few things compared to Maven 3, so make sure to run the mvnup tool before trying your project with Maven 4.

Issues fixed since RC-5

All known issues reported in the RC-5 release notes have been fixed:

Bean configuration bug — field accessibility state was cached globally, causing plugin configuration injection failures. Fixed in #11433.
Concurrency issue in the v4 API — a ConcurrentModificationException was fixed in #11429.
BOM packaging — consumer POM conversion for BOM projects now correctly preserves dependency versions. Fixed in #11464.
macOS Gatekeeper — the extracted JLine native binaries that triggered Gatekeeper have been removed from the distribution (#11997). The xattr workaround from RC-5 is no longer needed.

Known compatibility issues

The following are known compatibility issues when using Maven 4. Running
mvnup before building with
Maven 4 will fix many common plugin version issues automatically. The issues
below are those that require manual intervention or upstream fixes.

Stricter POM validation

Maven 4 enforces stricter validation than Maven 3. Projects may need to fix their POMs:

Duplicate XML elements — duplicate <artifactId>, <properties>, etc. are now rejected (Duplicated tag error). Fix the source POM.
Duplicate dependency declarations — same groupId:artifactId declared twice is now rejected (must be unique).
Uninterpolated expressions — ${...} expressions in repository URLs, distribution management IDs, and other fields that Maven 3 silently accepted are now rejected.
Invalid XML in transitive POMs — illegal processing instructions or undeclared namespace prefixes in transitive POMs cause Non-parseable POM errors.
Properties in <module> paths — Maven 4 no longer interpolates properties like ${spark.version} in <module> elements at POM reading time.
CI-friendly versions — projects using ${revision} without flatten-maven-plugin may hit missing dependency version errors.
Invalid Collect Request — transitive dependencies with uninterpolated ${...} version expressions are rejected.

Transitive dependency resolution changes

Maven 4's TransitiveDependencyManager applies dependencyManagement at all transitive depths (Maven 3 only applied it at the first level). This is intentional but can change resolved versions:

Dependencies previously on the classpath may disappear — add explicit declarations. See #12302.
maven-enforcer-plugin version rules may trigger due to downgraded transitive versions.
license-maven-plugin may report new transitive dependencies not in the allow-list.
Karaf feature verification may fail due to OSGi bundle version mismatches.

Plugin and extension compatibility

Some plugins and extensions require specific versions for Maven 4:

Quarkus — versions before 3.20 use ServiceLocator/RepositorySystem patterns incompatible with Maven 4's Sisu-based DI. Upgrade to Quarkus 3.20+.
Tycho — versions before 5.0 use Guice/Sisu injection patterns broken by Maven 4. Upgrade to Tycho 5.0.3+.
Develocity Maven extension — fails to initialize due to SLF4J classloading changes (ClassNotFoundException: SimpleLogger).
pgpverify-maven-plugin — versions before 1.20 hit a ClassCastException with Maven 4's resolver. See resolver#1957.
cyclonedx-maven-plugin — fails with Invalid Version Range Request when using ${revision} CI-friendly versions.
maven-site-plugin — Velocity template rendering may fail with incompatible site plugin versions.
maven-shade-plugin — dependency-reduced-pom.xml can cause The parents form a cycle error.
commons-release-plugin — clean-staging fails under Maven 4.

Classloading changes

Plugins relying on Maven 3's classrealm layout may encounter "foreign imports" errors (e.g., Quarkus, JAXB plugins).
Maven 4's prefix-based repository routing may block artifacts not matching /.meta/prefixes.txt.

Post-mvnup formatting

spotless-maven-plugin and sortpom-maven-plugin may report formatting violations after mvnup modifies POM files. Re-run the formatter after mvnup.

Other

Broken upstream POMs — e.g., hadoop-project 3.1.0–3.3.0 has invalid XML (<Xlint:-unchecked/>) causing parse errors. These need upstream fixes tracked in HADOOP-19923.
Enforcer POM element ordering — Maven 4's model builder reorders POM elements into a canonical order, which can break enforcer rules checking element ordering.
SNAPSHOT handling — SNAPSHOT artifacts may show as "present, but unavailable" under Maven 4's different resolver metadata handling.
