I doing my annotation processor which generate service file for current mod.

And I doing my mod which looking for such services in all mods in modpack.

Forge can provide location of mod, whether it is an jar or in-dev-folder.

The problem is getting actual location of service file.

For jar is trivially and work fine.

For in-dev-folder it's hard: File provided by Forge is not only one folder with mod files (look screenshot)

It's really problematic and now I'm stumped.

Any ideas?

Also I can consider other ways instead of services.

Some note: for example I made mod which looking for services and mod within services in one bottle, and you can see it on screenshot, but it's irrelevant to the problem.

If I use ServiceLoader, how it will work with multiple jars with identically named service files?

As I know, ServiceLoader resolves existence of multiple same service files by taking first.

It's also can resolve by ClassLoader, but I dont know, is Forge use separeted class loaders for each mod and is it be true it future.

Also, ServiceLoader gives instances of classes which specified in service, but I'm need to instances of Class<?> of these classes.

So, standard utility is not look as appropriate

all of them

Well. How to determine which class does the mod relate to?

make a service interface that provides that Class

Look excessive

Maybe it's a bad idea to call this thing as 'service'. Service is a most similar thing.

Generally thing which I need is a file with list of names of classes which been found(and generated) by my annotation processor and readable by my mod. And multiple mods in one modpack can contain such file

What?

Sorry, it's my wrong understanding of ServiceLoader

I found a pretty thing:

`IModLocator#findPath`

It's look as good solve to get actual location of "service" files for each mod
