I have a MavenLifecycleParticipant in my plugin. It uses
maven-dependency-tree to resolve some deps that we need to do extra
processing on. It works fine if the deps are in the local repo.
But if the s3 Wagon is defined in the project along with a dependency from
the s3 bucket, then the following debug log shows that
DependencyGraphBuilder of maven-dependency-tree can't resolve the s3 wagon,
and the dependency is not resolved now or later in the build, so
compilation fails.
NB If I remove the MavenLifecycleParticipant then the dep is resolved via
the S3 Wagon.
Q1) When are the Wagons configured? Shouldn't it be prior to
MavenLifecycleParticipant being called?
Q2) How can I get the DependencyGraphBuilder to resolve the s3 artifact
from within the MavenLifecycleParticipant?
Here is the stacktrace:
