Invoke two separate build scripts as a matrix on Travis CI

Question

I'd like to run Travis CI builds for two different build scripts. For example something like that:

• ./prepare.sh mvn verify -Psystem-tests
• ./prepare.sh mvn verify -Pintegration-tests

In documentation I see that Build Matrix feature is exactly what I need, but samples there refer only how to create matrix over different environments.

How can I create such matrix over different build commands?

Here's my current .travis.yml:

language: java
cache:
  directories:
    - $HOME/.m2
script:
  - ./prepare.sh
  - mvn verify -Psystem-tests
  - mvn clean verify -Pintegration-tests

In the matrix section, you can specify either:

• the commands themselves:

  matrix:
    - env: MAVEN_SCRIPT="mvn verify -Psystem-tests"
    - env: MAVEN_SCRIPT="mvn clean verify -Pintegration-tests"
  script:
    - ./prepare.sh
    - $MAVEN_SCRIPT
  

• which command to run, and then if on them:

  matrix:
    - env: MAVEN_TESTS=system
    - env: MAVEN_TESTS=integration
  script:
    - ./prepare.sh
    - if [ "$MAVEN_TESTS" == "system" ]; then mvn verify -Psystem-tests; fi
    - if [ "$MAVEN_TESTS" == "integration" ]; then mvn clean verify -Pintegration-tests; fi
  

• the specific parts that differentiate the tests:

  matrix:
    - env: MAVEN_TEST_CLEANLINESS=""    MAVEN_TESTS=system
    - env: MAVEN_TEST_CLEANLINESS=clean MAVEN_TESTS=integration
  script:
    - ./prepare.sh
    - mvn $MAVEN_CLEANLINESS verify -P$MAVEN_TESTS-tests
