How to get a newer maven version alongside JDK 17

[ghoshbishakh]

Description:

After setting up JDK 17, the maven version we get is 3.8.8
We want to get the latest maven version, 3.9.x

Here is the workflow:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Set up JDK
        uses: actions/setup-java@v4
        with:
          java-version: '17'
          distribution: 'temurin'
      - run: mvn --version

Task version:
v4

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Hello @ghoshbishakh, Thank you for creating this issue and we will look into it :)

Hi @ghoshbishakh, To use Maven version 3.9.9 alongside JDK 17, Maven needs to be manually installed since the ubuntu-latest runner image comes with Maven 3.8.8 by default. For reference, please visit https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2204-Readme.md.
Here is an updated workflow configuration:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Install latest Maven
        run: |
          MAVEN_VERSION=3.9.9
          wget https://downloads.apache.org/maven/maven-3/$MAVEN_VERSION/binaries/apache-maven-$MAVEN_VERSION-bin.tar.gz
          tar xzvf apache-maven-$MAVEN_VERSION-bin.tar.gz
          sudo mv apache-maven-$MAVEN_VERSION /opt/maven
          sudo rm -f /usr/bin/mvn  # Remove existing symbolic link if it exists
          sudo ln -s /opt/maven/bin/mvn /usr/bin/mvn  # Create new symbolic link
      - name: Set up JDK
        uses: actions/setup-java@v4
        with:
          java-version: '17'
          distribution: 'temurin' 
      - run: mvn --version

Thanks a lot @gowridurgad . I will try it out.

I think this should be reopened: 3.8.8 is not compatible with Java 17-based tools (fixed in apache/maven#1286 in 3.9.6), so it is important to be running a newer version.

Hi @jglick, We are able to use Maven version 3.8.8 alongside JDK 17. Attached a screenshot for your reference. However, if you need to use Maven 3.9.x, you can manually install it in your GitHub Actions workflow.

The difference here will be a Maven plugin compiled with Java 17. Before the fix in 3.9.6 Maven could build Java 17 projects but couldn't use Maven plugins with bytecode newer than Java 14.

Using Maven Wrapper is the easiest way to enforce a specific Maven version on most operating systems.
