These 2 ModuleInfo's seem to be the same, but contain different artifacts: the 'normal' and the 'native' version.

Note that this is not sbt.librarymanagement.ModuleInfo but sbtwhitesource.BaseAction$ModuleInfo.

[raboof]

For 'jar' and 'bundle' we have custom logic to select the 'bundle' (

sbt-whitesource/src/main/scala/sbtwhitesource/WhiteSource.scala

Line 253 in bff52e9

else if (Set(t1, t2) == Set("jar", "bundle")) Some("bundle")

), but that doesn't seem so clear-cut here. Perhaps this Map should really be a MultiMap?

[dwijnand]

I'm just going to discard the native module.

[dwijnand]

Btw, this is a change in behaviour from using Coursier, I'm pretty sure. Whether it's correct or not, I'm not.

[raboof]

Hrm, this problem still occurs for me... even when recreating the test at akka/akka#26963

Weird thing is the line numbers don't seems to correspond to the source, while lsof does seem to suggest the right jar was loaded... 😕

We're having a similar issue in Alpakka, but in this case, it's between two artifacts with the same group id and different classifiers (native and complete). We're using sbt-whitesource 0.1.18 and sbt 1.3.7.
