Amvn clean install -pl parent
Bmvn clean install -am
Cmvn clean install -pl child-module
Dmvn clean install -DskipTests

    -am means "also make" dependencies of the specified modules.
  2. Step 2: Choose command to build all needed modules

    Using mvn clean install -am builds the specified module and its dependencies, ensuring all modules are built.
  3. Final Answer:

    mvn clean install -am -> Option B
  4. Quick Check:

    Maven build dependencies = use -am flag [OK]
Quick Trick: Use -am to build dependencies with modules [OK]
Common Mistakes:
  • Using -pl without -am misses dependencies
  • Skipping tests when integration tests are needed
