Is there a way around this? Can I fetch the dependencies from other hosts?
Is it possible that you can distribute prebuild .jar files in the future? :)

[ScumbagDog]

Here's the missing dependency: https://github.com/msrd0/matrix-client/

Here are the jarfiles for both projects with all dependencies

Don't know if either works
Good Luck.

Thank you @ScumbagDog !
I am not familliar with maven and building software with it, but I think that I need to find another repository for the https://github.com/msrd0/matrix-client/ "libary?", since the listed one (maven.nextgenenergy.co.nz) is dead

[ScumbagDog]

If you want to continue to use maven to build with, yeah. I looked in the build script for the matrix-client project, and it had a task for publishing to the now-dead repo. If you set up a new server (or find a public to host it at), it should be as easy as redirecting the publish target in the matrix-client project and the repo in the Minetrix project (in the build.gradle and pom.xml respectively).

Alternatively, you could do what I did, which is clone both projects, make a "fat jar" (jar with dependencies included) of matrix-client, then just plop it in the Minetrix project folder and reroute the dependency to be local instead. It's a bit hacky (and besides, I already did that for you), so don't do this if you plan on developing the project further.

Just a FYI - it does not work with Paper for 1.16.3.
I have no idea why :)

Ok, I just checked the jarfile myself, and for some reason, the maven jar assembler decided to not include local dependencies when it made the all-dependencies version of the jar (this is some real galaxy-brain logic <.<).

I tried my hand at merging it manually, let me know if it works.
Minetrix-0.1.0-SNAPSHOT-jar-with-dependencies.zip

Thank you @ScumbagDog!
This did indeed solve the issue :)
I am however getting this error, and I do not think that it has something to do with the .jar file at all. Maybe the package needs to be updated since stuff has change quite alot in the matrix-ecosystem lately:

I found this repo of matrix-client, maybe it is updated to work with the application_service api:
https://gitlab.com/mextrix/matrix-client
Otherwise, you may be able to specify a legacy version of the api to be used.
But your guess is as good as mine.
