fbjni: Could not find a package configuration file provided by "fbjni"

very simple go to build.gradle of project and change enablHermes true -> false…

Adding jcenter() under allprojects in build.gradle worked for me

Adding jcenter() under allprojects in build.gradle worked for me

This works for me too! But, isn’t jcenter supposed to be shutting down by February 2022? What’s the root cause of this? Is there a better solution?

I think I got this working by adding

configurations {
	all*.exclude module: 'fbjni-java-only'
}

I’m not sure yet whether this is a perfect approach, but it builds after cleaning as well as afterward. Changes on my repo.

Just extend android/grafle.properties by adding:

android.prefabVersion=2.0.0

I got this building(I pushed the commit to my repo) more or less doing the same as you, that does not mean I got this fully working as I don’t have a code using fbjni but I’ll try to push something like that, thx anyway. I for sure will leave the repo with the commits ‘before’ and ‘after’ for anyone having similar problems 🙌

Also please, don’t close this issue for now, I’d like to make sure this works and write down some thoughts etc(I know we overcame this particular problem and we could close this and open a new one, but I see you guys don’t have a lot of issues here so maybe we can deal with anything on the way in this one?).

This still gives me errors about duplicate classes(I’m referring to the code from the commit I pasted above).

The latter is I find the documentation about the installation a little bit incomplete(?) 🤔 maybe not the best word, I mean it could be better - those things regarding building as well as, for instance, the flow of registering a hybrid class and all that stuff to make a JNI connection in fbjni(in jni it’s pretty clear).

I’m definitely open to suggestions here. Sadly the universe of potential Gradle errors is nearly infinite and depends so much on what you are trying to build. If you just google for “duplicate classes gradle” you’ll find an endless stream of cases. We can’t really anticipate every one of them here, but if there’s a particular advice we can give, I’d love to add that to the docs.

@passy, I create a pure native project https://github.com/psionic12/fbjni_demo, it has nothing to do with React Native, just trying to use fbjni. In this case, when using prefab=true, as long as the implementation ‘com.facebook.fbjni:fbjni:0.1.0’ is added, executing external native build for cmake occurs. It seems that fbjni use some Cmake files which is not in 0.1.0 package.

The error message isn’t great but by telling you

User is using a static STL but library requires a shared STL

it’s saying that you need to target a shared C++ runtime. If you add this to your project, it builds:
