I agree ist not entirelly fixed on any language yet as you mentioned Python has it not only well nailed plus using virtual envs plus virtual env manages (pipenv for example).

In java is basically a non existing problem, you CAN have dependency conflicts yes, nontheless dependency management is simple, and you keep everithing on a local central repo when using maven, which also provides a very nice dependency tree plus tools for filtering, whicg are nice, which of course you can also achieve with grep for even easier dependency conflict debugging.

Also using tools as dependencyManagement in maven allows you to replace all usages of a library across your entire application "at your own risk" which simplifies addressing security vulnerabilities
