# Two stage Build and Test
# 1. Install & Unit Test APIs
# 2. Assemble DSpace
script:
  # 1. [Install & Unit Test] Check source code licenses and run source code Unit Tests
  #        license:check => Validate all source code license headers
  #        -Dmaven.test.skip=false => Enable DSpace Unit Tests
  #        -DskipITs=false         => Enable DSpace Integration Tests
  #        -P !assembly            => Skip normal assembly (as it can be memory intensive)
  #        -B => Maven batch/non-interactive mode (recommended for CI)
  #        -V => Display Maven version info before build
  #        -Dsurefire.rerunFailingTestsCount=2 => try again for flakey tests, and keep track of/report on number of retries
  - "mvn clean install license:check -Dmaven.test.skip=false -DskipITs=false -P !assembly -B -V -Dsurefire.rerunFailingTestsCount=2"
  # 2. [Assemble DSpace] Ensure assembly process works (from [src]/dspace/), including Mirage 2
  #        -Dmirage2.on=true => Build Mirage2
  #        -Dmirage2.deps.included=false => Don't include Mirage2 build dependencies (We installed them in before_install)
  #        -P !assembly => SKIP the actual building of [src]/dspace/dspace-installer (as it can be memory intensive)
  - "cd dspace && mvn package -Dmirage2.on=true -Dmirage2.deps.included=false -P !assembly -B -V -Dsurefire.rerunFailingTestsCount=2"
