Pantsbuild: how to skip JVM class duplicates for a Scala library?

57 views Asked by At

I'm using pants v1.30.0 and I need to find a workaround to build a Scala fat JAR that includes pureconfig v0.14.0.

Pantsbuild detect-duplicates:

Detect JVM classes and resources with the same qualified name on the classpath.

I'm experiencing the following issue:

$ ./pants detect-duplicates src/scala/myapp:main
...
 [detect-duplicates]

  • Is it possible to tell pants to skip this check?
  • If I wanted to fix pureconfig duplicate issue by myself what would be the currect way to do it?
