# Base installation directory the Maven distribution
maven_install_dir: /opt/maven

Advanced Configuration

The following role variable is dependent on the Maven version; to use a Maven version not pre-configured by this role you must configure the variable below:

# SHA256 sum for the redistributable package (i.e. apache-maven-{{ maven_version }}-bin.tar.gz)
maven_redis_sha256sum: '6e3e9c949ab4695a204f74038717aa7b2689b1be94875899ac1b3fe42800ff82'

Example Playbooks

By default this role will install the latest version of Maven supported by this role:

- hosts: servers
  roles:
    - role: gantsign.maven

You can install a specific version of Maven by specifying the maven_version (note: if the version is not currently supported by this role then additional configuration will be required - see Advanced Configuration):

- hosts: servers
  roles:
    - role: gantsign.maven
      maven_version: '3.3.9'

You can install the multiple versions of Maven by using this role more than once:

- hosts: servers
  roles:
    - role: gantsign.maven
      maven_version: '3.3.9'
      maven_is_default_installation: true
      maven_fact_group_name: maven

    - role: gantsign.maven
      maven_version: '3.2.5'
      maven_is_default_installation: false
      maven_fact_group_name: maven_3_2

Role Facts

This role exports the following Ansible facts for use by other roles:

• ansible_local.maven.general.version

  • e.g. 3.3.9

• ansible_local.maven.general.home

  • e.g. /opt/maven/apache-maven-3.3.9

Overriding maven_fact_group_name will change the names of the facts e.g.:

maven_fact_group_name: maven_3_2

Would change the name of the facts to:

• ansible_local.maven_3_2.general.version
• ansible_local.maven_3_2.general.home
