Gradle: how to display where a dependency conflict

Question

I have a Gradle project with many dependencies, one of which is resolved as follows:

gradle dependencyInsight --configuration compile --dependency javax.activation

:dependencyInsight
javax.activation:activation:1.1 (conflict resolution)
+--- com.sun.mail:mailapi:1.4.4
|    \--- compile
\--- com.sun.mail:smtp:1.4.4
     \--- compile

javax.activation:activation:1.0.2 -> 1.1
\--- compile

Version 1.1 must be a transitive dependency because I explicitly specified 1.0.2. How can I find out where this specific transitive dependency comes from?

Answer 1

Answering this question is the whole point of the dependencyInsight task. javax.activation:activation:1.1 is pulled in by com.sun.mail:mailapi:1.4.4 and com.sun.mail:smtp:1.4.4.

If your own code also depends on javax.activation, you can force your version with compile("javax.activation:activation:1.0.2") { force = true }. If not, you can force a version with configurations.all { resolutionStrategy.force "javax.activation:activation:1.0.2" }.
