Summary

Replaces the external plexus-classworlds dependency with an internalized maven-classworlds module and adds JPMS module support to enable targeted --enable-native-access for JLine, replacing the broad ALL-UNNAMED flag.

Internalize plexus-classworlds

  • Copy plexus-classworlds source into impl/maven-classworlds, maintaining original package structure
  • Extract org.apache.maven.api.classworlds into a separate API module (api/maven-api-classworlds)
  • Replace all plexus-classworlds dependencies across the build with maven-classworlds
  • Fully eliminate plexus-classworlds from the dependency tree

Targeted --enable-native-access for JLine (fixes #11028)

  • Move JLine jars to lib/modules/ and load them on the boot --module-path via a new module directive in m2.conf
  • Add --add-modules ALL-MODULE-PATH to resolve modules on the module-path
  • Replace --enable-native-access=ALL-UNNAMED with targeted --enable-native-access=org.jline.terminal.ffm,org.jline.nativ
  • Add Java version detection in launcher scripts — skip module flags on JDKs that don't support them

Runtime ModuleLayer with module access control

  • Add add-exports, add-opens, add-reads directives to m2.conf configuration parser
  • Create a runtime ModuleLayer in Configurator for modules not already in the boot layer, with Controller-based access control
  • Store ModuleLayer and Controller on ClassWorld for realm-level access
  • Add ClassRealm.addExports() and ClassRealm.addOpens() methods for plugins/extensions to control module access at runtime
  • Process META-INF/maven/module-access descriptor files in DefaultClassRealmManager.createRealm() — applies to all realm types (plugin, extension, project)

Descriptor format: META-INF/maven/module-access

Plugins and extensions can declare module access requirements:

# Export a package from a named module to the plugin's classloader
add-exports org.jline.terminal/org.jline.terminal.spi
# Open a package for deep reflection
add-opens org.jline.reader/org.jline.reader.impl

Files changed (key files)

File Change
apache-maven/src/assembly/maven/bin/mvn Module-path, add-modules, targeted enable-native-access
apache-maven/src/assembly/maven/bin/mvn.cmd Same for Windows
apache-maven/src/assembly/maven/bin/m2.conf module directive for JLine jars
impl/maven-classworlds/ Full internalized classworlds implementation
api/maven-api-classworlds/ New classworlds API module
ConfigurationHandler.java addExports, addOpens, addReads callbacks
ConfigurationParser.java Parse add-exports, add-opens, add-reads directives
Configurator.java Runtime ModuleLayer creation and directive application
ClassWorld.java ModuleLayer + Controller storage
ClassRealm.java addExports(), addOpens() runtime API for plugins
DefaultClassRealmManager.java META-INF/maven/module-access descriptor processing

Test plan

  • mvn verify -pl impl/maven-classworlds — 93 tests pass
  • mvn install -DskipTests — full build succeeds
  • mvn --version — clean output, no warnings
  • mvn validate — JLine terminal works correctly

Closes #11029

Should we maybe at the same time archive/EOL plexus-classworlds?
Also, is this a fork of it? Or rewrite? As if some third-party may use plexus-classworlds, is this new module drop in replacement?

I'm not sure if we need copy it to Maven core ...
Why not simply update plexus-classworlds?

Especially that old java package and old licenses header are preserved

This is currently a fork, and I removed the old layer already.

I'm not sure if we need copy it to Maven core ... Why not simply update plexus-classworlds?

Especially that old java package and old licenses header are preserved

This was really a first step. I was toying a bit to solve a few limitations:

One important point is that extensions should be able to provide controlled access to some API, which could be consumed by plugins. Plugins themselves could export some packages, I think we had some use cases for that (we currently need an extension to do that).

So not sure yet, this is just experiments... but ideas welcomed. Overall, I think plexus-classworlds won't be able to solve the above problems, and given Maven is really the only user afaik, I'm tempted to merge ...

877664a 
…assworld to separate API module

- Remove jline-native references from Maven launcher scripts (mvn and mvn.cmd)
- Remove jline-native dependencies and configurations from POMs
- Remove module-info.java file from maven-classworlds
- Remove jline-native assembly configurations and README
- Create new maven-api-classworlds module in api/ directory
- Move org.apache.maven.api.classworlds package to new API module
- Update dependency management and module references
- Add maven-api-classworlds dependency to modules that use the API

This change separates the public API from the implementation, following Maven 4
architecture patterns, and removes the JPMS and jline-native dependencies that
were causing complexity in the build and runtime environment.

- Exclude plexus-classworlds transitive dependency from Sisu and
  plexus-testing in root pom dependencyManagement
- Add maven-classworlds test dependency to maven-resolver-provider
  (needed by plexus-testing at runtime)
- Copy legacy org.codehaus.classworlds adapter classes into
  maven-classworlds (required by Sisu's ClassRealmConverter and
  AbstractComponentConfigurator)
- Add checkstyle exclusion for legacy package and RAT exclusion
  for test data

[ISSUE-11028] Enable targeted --enable-native-access for JLine modules
bb04144 
Move JLine jars from lib/ to lib/modules/ and load them via
--module-path + --add-modules ALL-MODULE-PATH so that
--enable-native-access can target org.jline.terminal.ffm and
org.jline.nativ by name instead of using the broad ALL-UNNAMED.

Changes:
- Add `module` directive to classworlds ConfigurationParser with
  glob support, mirroring the existing `load` directive
- Separate JLine jars into lib/modules/ in the assembly descriptor
- Update m2.conf with `module ${maven.home}/lib/modules/*.jar`
- Update mvn/mvn.cmd launcher scripts to use --module-path,
  --add-modules ALL-MODULE-PATH, and targeted --enable-native-access
- Update LICENSE.vm to classify JLine under lib/modules/

default methods returning boolean for success feedback. Synchronize
setModuleLayer. Support add-reads in module-access descriptors and log
on failure.

[ISSUE-11028] Fix binary compat and Java 17 support
00bf58c 
- Use void return type for addExports/addOpens/addReads to preserve
  binary compatibility on the ClassRealm class
- Remove redundant @SInCE tags (interface already has @SInCE 4.1.0)
- Conditionally enable --module-path and --enable-native-access only
  on Java 21+ (FFM API not available on Java 17)
- Add classpath fallback in Configurator when ModuleLayer creation
  fails (e.g. module jars reference unavailable APIs)

Launcher and maven-executor use reflection to find main(String[], ClassWorld)

NoSuchMethodException at runtime. Use FQ org.codehaus.plexus.classworlds.ClassWorld
in all main() method parameters while keeping the API import for ProtoLookup mapping.

since cygpath --windows with a wildcard in the path can cause issues on
MinGW/Git Bash. Also convert MODULES_DIR to Windows format and construct

[ISSUE-11028] Preserve binary compat for ClassRealmManagerDelegate
f889114 
ClassRealmManagerDelegate.setupRealm() is an SPI that extensions implement.
Changing its ClassRealm parameter type from impl to API breaks pre-compiled
extensions. Revert the interface to use the impl ClassRealm type and cast
in DefaultClassRealmManager. Also revert IT test sources and remove
temporary CI debug logging.

[ISSUE-11028] Include JLine jars in lib/ for embedded executor compat
29413dc 
JLine jars were exclusively placed in lib/modules/ for JPMS module
path usage, but the EmbeddedMavenExecutor constructs its classpath
from lib/ only. Include JLine in both locations — the JVM's module
system prefers module path over classpath, so there's no conflict
when both paths are active.

Pull request overview

This PR internalizes plexus-classworlds into a new maven-classworlds implementation module, introduces a new public API module (maven-api-classworlds), and updates Maven’s distribution/launching to support JPMS modules (notably loading JLine from a module path to enable targeted --enable-native-access).

Changes:

  • Replace external plexus-classworlds with internal maven-classworlds + new maven-api-classworlds API and update imports/usages across core/cli/compat.
  • Update Maven distribution + launcher scripts (mvn, mvn.cmd, m2.conf, assembly component) to load JLine from lib/modules and use targeted native-access flags.
  • Add/port classworlds tests and legacy compatibility shims (org.codehaus.classworlds.*) to preserve ecosystem compatibility (e.g., Sisu).
