Extract quickfixj-codegenerator into standalone Maven plugin module

[Copilot]

Extracts quickfixj-codegenerator from the quickfix-j/quickfixj multi-module build into a self-contained, independently releasable Maven plugin module at version 3.0.1-SNAPSHOT — the same pattern applied to quickfixj-class-pruner-maven-plugin in PR #1184.

quickfixj-codegenerator/pom.xml

• Removed <parent> block; added standalone <groupId>, <version>, <licenses>, <developers>, <scm>, <issueManagement>, <prerequisites>
• All dependency and plugin versions now explicit via self-contained <properties>
• Added <build><pluginManagement> for compiler, source, javadoc, gpg, nexus-staging plugins
• Added profiles: java-8-compilation (JDK ≥ 9 activates maven.compiler.release=8), release, sign
• Added <distributionManagement> targeting GitHub Packages (snapshots) and OSSRH (releases)

New files in quickfixj-codegenerator/

• .github/workflows/maven.yml — CI matrix: ubuntu + macOS-14 × JDK 8/11/21
• .gitignore — standard Maven/IDE ignores
• LICENSE — QuickFIX Software License v1.0

Root pom.xml

• Removed <module>quickfixj-codegenerator</module>
• Added <codegenerator-plugin.version>3.0.1-SNAPSHOT</codegenerator-plugin.version> property
• Added pluginManagement entry pinning the plugin to ${codegenerator-plugin.version}

Downstream references

• quickfixj-messages-all/pom.xml and quickfixj-distribution/pom.xml: codegenerator version changed from ${project.version} → ${codegenerator-plugin.version}
• .github/workflows/nightly-build.yml: removed org.quickfixj.quickfixj-codegenerator from the "Delete old packages" step

Original prompt

Goal

Extract the quickfixj-codegenerator Maven plugin from the quickfix-j/quickfixj multi-module build into a standalone, self-contained module — exactly the same pattern as was done for quickfixj-class-pruner-maven-plugin in PR #1184.

The standalone version should be 3.0.1-SNAPSHOT.

Changes required

1. Transform quickfixj-codegenerator/pom.xml into a standalone POM

Remove the <parent> block and make it a fully self-contained POM:

• Add <groupId>org.quickfixj</groupId>
• Add <version>3.0.1-SNAPSHOT</version>
• Add <licenses> block (The QuickFIX Software License, Version 1.0, http://www.quickfixj.org/documentation/license.html)
• Add <developers> block: id=chrjohn, name=Christoph John
• Add <scm> block pointing to https://github.com/quickfix-j/quickfixj-codegenerator
• Add <issueManagement> block pointing to https://github.com/quickfix-j/quickfixj-codegenerator/issues
• Add <prerequisites><maven>3.9.12</maven></prerequisites>
• In <properties>, add all version properties explicitly (don't rely on parent):
  • project.build.sourceEncoding = UTF-8
  • project.reporting.outputEncoding = UTF-8
  • maven.compiler.source = 8
  • maven.compiler.target = 8
  • maven-libs-version = 3.9.12
  • maven-plugin-api-version = 3.9.14
  • maven-plugin-annotations.version = 3.15.2
  • junit.jupiter.version = 5.14.3
  • commons-io.version = 2.21.0
  • maven-surefire-plugin-version = 3.5.5
  • maven-compiler-plugin-version = 3.15.0
  • maven-source-plugin-version = 3.4.0
  • maven-javadoc-plugin-version = 3.12.0
  • maven-gpg-plugin-version = 3.2.8
  • nexus-staging-maven-plugin-version = 1.7.0
• In all <dependency> entries that used to inherit versions from parent, add explicit <version> tags using the above properties
• Add a <build><pluginManagement> section that defines explicit versions for: maven-compiler-plugin (with <forceLegacyJavacApi>true</forceLegacyJavacApi>), maven-source-plugin (with attach-sources execution), maven-javadoc-plugin (with attach-javadocs execution, <quiet>true</quiet><doclint>none</doclint>), maven-gpg-plugin (with sign-artifacts execution), nexus-staging-maven-plugin (with ossrh configuration)
• Keep the existing build plugins (maven-jar-plugin, maven-source-plugin, maven-pmd-plugin, maven-plugin-plugin) but add explicit versions for maven-surefire-plugin
• Add a <profiles> section with:
  • java-8-compilation profile (activated on JDK >= 9, sets maven.compiler.release=8)
  • release profile (activates maven-source-plugin, maven-javadoc-plugin, nexus-staging-maven-plugin)
  • sign profile (activates maven-gpg-plugin)
• Add <distributionManagement>:
  • <snapshotRepository> id=github, url=https://maven.pkg.github.com/quickfix-j/quickfixj-codegenerator
  • <repository> id=ossrh, url=https://oss.sonatype.org/service/local/staging/deploy/maven2/

2. Add quickfixj-codegenerator/.github/workflows/maven.yml

Create this file:

name: Java CI

on:
  workflow_dispatch:
  push:
  pull_request:
    types: [reopened, opened, synchronize]

jobs:
  test:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest, macOS-14]
        java: [8, 11, 21]
      fail-fast: false
      max-parallel: 4
    name: Test JDK ${{ matrix.java }}, ${{ matrix.os }}

    steps:
      - uses: actions/checkout@v4
      - name: Set up JDK
        uses: actions/setup-java@v4
        with:
          distribution: 'corretto'
          java-version: ${{ matrix.java }}
          cache: 'maven'
      - name: Test with Maven
        run: mvn install -B -V -D"maven.javadoc.skip"="true"

3. Add quickfixj-codegenerator/.gitignore

Create this file:

# ignore maven build directories
target/
# ignore maven wrapper jar that gets built locally
.mvn/wrapper/maven-wrapper.jar
# ignore Eclipse configuration files
.project
.classpath
.settings
# ignore IntelliJ configuration files
.idea/
*.iml
*.ipr
*.iws
# ignore NetBeans configuration
nb-configuration.xml
*.bak
# ignore vim swap files
*.swp

4. Add quickfixj-codegenerator/LICENSE

Copy the existing LICENSE text used in the class-pruner plugin (The QuickFIX Software License, Version 1.0).

5. Update root pom.xml

• Remove the module entry <module>quickfixj-codegenerator</module> from the <modules> section
• Add property <codegenerator-plugin.version>3.0.1-SNAPSHOT</codegenerator-plugin.version> to the <properties> section
• Add a <plugin> entry in <build><pluginManagement><plugins> for the codegenerator:

  <plugin>
      <groupId>org.quickfixj</groupId>
      <artifactId>quickfixj-codegenerator</artifactId>
      <version>${codegenerator-plugin.version}</version>
  </plugin>

6. Update quickfixj-messages/quickfixj-messages-all/pom.xml

Change the codegenerator plugin version from ${project.version} to ${codegenerator-plugin.version}:

<plugin>
    <groupI...
