Gradle multi project transitive dependency

Question

I have three gradle<\/code> projects. Say ProjectA<\/code> , ProjectB<\/code> and ProjectC<\/code> .

While ProjectB<\/code> is dependent on ProjectA<\/code> .

dependencies {
  implementation project(':ProjectA')
  implementation project(':ProjectB')
}

Answer 1

Because implementation is precisely for that: it tells that ProjectA is needed for the code of ProjectB to work (internally), but is not part of its API (ie you don't want clients of ProjectB to rely on the fact that it uses ProjectA internally).

If you want ProjectA to be part of the API or ProjectB, then use the api configuration rather than implementation.

See the guide for more details.

Answer 2

Add

plugins {
    id 'java-library'
}
