From 72f15000996ade44966a6efe69feacaed0eb9ee0 Mon Sep 17 00:00:00 2001 From: Guillaume Nodet Date: Sat, 9 Aug 2025 13:39:00 +0000 Subject: [PATCH 01/14] Remove jline-native and JPMS support, extract org.apache.maven.api.classworld 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.

+ * This package provides the public API for Maven's class loading system, which allows + * for isolated class loading environments (realms) with controlled imports and exports + * between them. + *

+ *

+ * Key concepts: + *

+ *
    + *
  • {@link org.apache.maven.api.classworlds.ClassWorld} - A container for multiple class realms
    • + *
  • {@link org.apache.maven.api.classworlds.ClassRealm} - An isolated class loading environment
    • + *
  • {@link org.apache.maven.api.classworlds.Strategy} - Defines class loading delegation behavior
    • + *
  • {@link org.apache.maven.api.classworlds.ClassWorldListener} - Listens to realm lifecycle events
    • + *
+ *

+ * This API follows Maven 4 conventions: + *

+ *
    + *
  • Only public interfaces and enums are exposed
    • + *
  • All interfaces are marked as {@code @Experimental}
    • + *
  • Proper nullability annotations are used
    • + *
  • Implementation details are hidden behind the API

eliminate plexus-classworlds from the dependency tree - 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 Co-Authored-By: Claude Opus 4.6 --- compat/maven-resolver-provider/pom.xml | 5 +

This package has been deprecated since version 2.5.2 (2014). New code should use + * {@code org.codehaus.plexus.classworlds} instead.

+ * + *

Do not remove this package. The compiled bytecode of + * {@code org.eclipse.sisu:org.eclipse.sisu.plexus} references {@link ClassRealm}, + * {@link ClassRealmAdapter}, and {@link ClassRealmReverseAdapter} from this package. + * Removing them causes {@code ClassNotFoundException} at runtime for any application + * using Sisu, including all Maven 3+ builds.

+ * + *

PR #141 removed this package and had to be reverted immediately (commit 223416e). + * See {@code COMPATIBILITY.md} for details on what Sisu references and what preconditions + * must be satisfied before any future removal.

Purpose

+ *

+ * When a plugin (or extension) runs on the classpath (unnamed module) it may need to + * call into packages of a named module that lives in Maven's boot/runtime layer — + * for example JLine modules in {@code lib/modules/}, or any future Maven API module that ships + * as a named module. Named modules do not export their internals to the unnamed module by + * default; the JVM enforces this at runtime via strong encapsulation. + *

+ *

+ * The {@code META-INF/maven/module-access} file is a plugin-side escape hatch: it lets the + * plugin declare which packages of which boot-layer modules it needs opened or exported + * to itself (always {@code ALL-UNNAMED} as the target). Maven applies these + * directives programmatically via {@link Module#addExports}/{@link Module#addOpens} on startup + * of the plugin realm, before any plugin class is loaded. + *

+ * + *

Direction of access

+ *

+ * Directives go from an existing named module in the boot/runtime layer + * to the unnamed-module classloader of the plugin. In other words: + * a plugin cannot use this mechanism to export its own packages; it can only + * widen access from modules that Maven already owns (and that are loaded before the plugin). + *

+ * + *

File format

+ *

Each non-blank, non-comment line is one of:

+ * 
+     *   add-exports <module>/<package>=ALL-UNNAMED
+     *   add-opens   <module>/<package>=ALL-UNNAMED
+     *   add-reads   <module>
+     *
+ *

+ * These mirror the JVM flags {@code --add-exports}, {@code --add-opens}, and + * {@code --add-reads} respectively. Lines starting with {@code #} are comments. + *

+ * + *

Why not {@code module-info.java}?

+ *

+ * The boot-layer modules (e.g. JLine) are compiled independently and cannot reference + * the plugin's module name at compile time. Adding {@code exports … to plugin.module} in + * their {@code module-info} would create an unacceptable coupling. Programmatic + * {@code addExports}/{@code addOpens} is the standard JDK-endorsed workaround for + * this exact scenario (see {@link java.lang.Module#addExports}). + *
