java - How does maven resolve a parent pom? -


i came accross problem , want understand it.

story

maven version 3.2.1. had multi-module project structure this:

mainmodulea -pom.xml -submoduleb --pom.xml --submodulec ---pom.xml -submoduled --pom.xml --submodulee ---pom.xml

the submodules child of module in parent folder. none of them have relativepath in parent element in pom, means far know ../pom.xml. problem was, submodulec has become new dependency, , submodulee depending on submodulec. version of new dependency of submodulec managed in mainmodulea. in local repository , in company repository still old version of mainmodulea, did not contain managed version. workspace folder structure contained correct mainmodulea pom. if have built submodulee alone, have got warning transitive dependencies of submodulec ignored because of missing managed version, , results compilation errors.

resolution priority

what order of possibilities used maven parent pom?

based on experience above:

  1. maven local repository
  2. maven remote repository
  3. tracking down in folder structure based on relativepath tags of parent tags.

am right statements above? can prove somehow? did not find relevant documentation.
