Solved paper equivalent to spigot BuildTools

[senneb]

Until now I have always used spigot, but paper has a beter performance. I need to know how to install and use the paper equivalent to BuildTools, I would prefer mojang mappings if this is an option.

Take a look at https://github.com/PaperMC/paperweight-test-plugin. Its a Gradle plugin you use to use mojang-mapped nms in your plugin at development time, and then reobf your plugin to obfuscated mappings at build.

Note that this is the only supported way of using minecraft internals with paper in a plugin.

Is there no way to use maven?

We don't support using maven with nms internals. You can use maven with the paper api just fine. There is a 3rd party maven plugin that adds this functionality, but its not supported here or in other paper support channels.

Trying to run a mojang mapped plugin on a spigot mapped server, you need to make sure that you remap the jar using the reobfJar task if using userdev, and grab the correct jar

 

[senneb]

how do i fix it?

 

[electronicboy]

assuming that you're using the gradle userdev stuff, make sure that you run the reobfJar task, and use the correct jar (the none -dev one)

 

[senneb]

No i am ussing the maven thing

 

[electronicboy]

I can't provide support for that thing, you'd need to work out how to get it to produce a remapped jar

 

[senneb]

do i need to run the maven remap?

 

[senneb]

do you know how i can change it to gradle?

 

[senneb]

I did change to gradle, and I ussed the example plugin, but how do I add dependencies?
