How to find dependency conflicts in 3rd party libraries

I'm looking for a way to find dependency conflicts in 3rd party libraries. I'm aware of mvn dependency:tree, its -Dverbose and -Dincludes options. This works well but has a couple of drawbacks:

I need to set up a pom.xml file with the 3rd party dependency. This is a somewhat roundabout way and tedious for quickly looking through the dependencies of a couple of libraries.
dependency:tree downloads all dependencies, which can be slow and consume a lot of bandwidth for large dependency graphs.
dependency:tree -Dverbose does show conflicts but it is quite verbose as it also shows all non conflicting dependencies.

Solution

The CLI of the Coursier dependency resolver can do this. E.g. to find dependency conflicts in com.bynder:bynder-java-sdk:2.2.8 you can use Coursier's resolve command with the --conflict flag:

$ cs resolve --conflicts   com.bynder:bynder-java-sdk:2.2.8 

org.jetbrains.kotlin:kotlin-stdlib-common:1.4.10 was selected, but
  com.squareup.okio:okio:2.8.0 wanted version 1.4.0

io.reactivex.rxjava2:rxjava:2.2.20 was selected, but
  com.squareup.retrofit2:adapter-rxjava2:2.9.0 wanted version 2.0.0

com.squareup.okhttp3:okhttp:4.9.0 was selected, but
  com.squareup.retrofit2:retrofit:2.9.0 wanted version 3.14.9

org.jetbrains.kotlin:kotlin-stdlib:1.4.10 was selected, but
  com.squareup.okio:okio:2.8.0 wanted version 1.4.0

This outputs a list of conflicts and nothing more. No artifacts are downloaded besides its metadata and the whole process is very quick.

To further explore where the conflict on e.g. com.squareup.okhttp3:okhttp is coming from, you can run

$ cs resolve com.bynder:bynder-java-sdk:2.2.8 --what-depends-on com.squareup.okhttp3:okhttp
  Result:
└─ com.squareup.okhttp3:okhttp:4.9.0
   ├─ com.squareup.okhttp3:logging-interceptor:4.9.0
   │  └─ com.bynder:bynder-java-sdk:2.2.8
   └─ com.squareup.retrofit2:retrofit:2.9.0 com.squareup.okhttp3:okhttp:3.14.9 -> 4.9.0
      ├─ com.bynder:bynder-java-sdk:2.2.8
      ├─ com.squareup.retrofit2:adapter-rxjava2:2.9.0
      │  └─ com.bynder:bynder-java-sdk:2.2.8
      └─ com.squareup.retrofit2:converter-gson:2.9.0
         └─ com.bynder:bynder-java-sdk:2.2.8

The output is an inverse dependency tree showing all subtrees that depend on com.squareup.okhttp3:okhttp.
