Resolver Extras

Artifacts:

conditional-a

An example artifact that optionally depends on conditional-b.

conditional-b

An example artifact that has activationCondition in form of artifactPresent(org.slf4j:slf4j-api).

consumer-a

An example artifact that declares capability consumption on label slf4j-backend.

provider-a

An example artifact that declares capability provider on label slf4j-backend.

Examples

capability

• Case1: mvn package build FAILS - consumption not satisfied.
• Case2: mvn package -P satisfy, here profile pulls in provider-a and consumption is satisfied, build SUCCEEDS.
• Case3: mvn package -P discover, here profile provides instructions how to discover provider, build SUCCEEDS.

PoC:

TBD

conditional

• Case1: mvn toolbox:tree dependency slf4j-simple is absent from tree (condition is not satisfied).
• Case2: mvn toolbox:tree -P satisfy, dependency slf4j-simple is present in tree (condition is satisfied).
