Maven produces a number of warnings of omissions and duplications in the POMs.
They are probably benign, but it would be better to fix the POMs to eliminate the warnings so that build behavior is prescriptive and other more important warnings are not masked.
Summary of the warnings:
Duplicate declaration of scala plugin.
Affects: typesystem, hdfs-model, storm-bridge
No version for scala plugin.
Affects: atlas (root), graphdb\titan0, webapp
Duplicate declaration of org.apache.atlas:atlas-repository:jar:tests
No version for keytool-maven-plugin
For most of the warnings the fix is obvious. For versions of the plugins I am assuming that the most recent versions are satisfactory: i.e.
- scala plugin version 3.2
- keytool plugin version 1.5.
