Docker: where is located PMS?

[Maelep]

I'm trying to write a docker image based on yours but I don't understand -cp ums.jar net.pms.PMS.
Where is located net.pms.PMS? I don't find it anywhere in the folder your copy.
I made a copy of your /usr/src/ums that you copy in your docker image but net.pms.PMS isn't located there.

@Maelep net.pms.PMS is a reference to the main Java class, it's not a file or folder. -cp stands for classPath and is documented at https://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html

Did you see our dockerfile? https://github.com/UniversalMediaServer/UniversalMediaServer/blob/master/docker/Dockerfile

[Maelep]

Yes, I made mine from yours.
I'm trying to develop some features to add that's why I'm mounting my volumes.

If it isn't finding the classpath in the .jar file, it might mean it's not the right jar file, like it hasn't been built correctly

Thank you for your answer. I managed to make it runs (I wasn't using the good release...).
By the way, I get some error when trying to read YouTube channels:

I'm glad it's working now :) if you create a new issue following the instructions for the YouTube problem I can look into it https://github.com/UniversalMediaServer/UniversalMediaServer/issues/new

[Maelep]

I'll make more tests before opening an issue, perhaps I made an error in my configuration.
Thank you for your answers.

For future reference, this problem was caused by the wrong .jar file being used: #2739 (reply in thread)
