Android: Could not resolve project :unityLibrary. ... / No matching configuration of project :unityLibrary was found.

Dear all,

I try to build an existent React_Native project with your library :

• I obtain the build failure described below :

- Would you have already met this problem ?

Thank's a lot.

same error!

[psbdgr8]

@PandaNut did you follow the steps ? because it looks like the module is not able to find the Android Exported files. go through the steps once again.

[Luluno01]

I have the same issue. I am using Expo in managed mode, and I got the same error after installing this package even before I import it in my code or updating the Gradle files. After updating the Gradle files the error persists.

Hi @Luluno01 , @uasad1099 , @PandaNut did you solve this issue ?

[Luluno01]

Hi @Luluno01 , @uasad1099 , @PandaNut did you solve this issue ?

Cause

Yes. Sorry I forgot there is such an issue. In my case, it is caused by:

1. The project was auto-linked by Expo, and this behavior was not able to be disabled (I followed the docs to disable but somehow it was still auto-linked)
2. There is no Unity project I exported and registered to Gradle build files at that time.

My Solution

So, my solution was to vendor this package, in order to forcibly exclude it from auto-linking, and then manually link it through custom config plugins modifying the Gradle build files (as instructed in the README, with an extra dependency entry that points to the vendored source code of this package, and an extra line of code in MainApplication.java that registers the native view) when the feature is enabled explicitly in app config.

Alternatively, I assume you can simply install this package and make sure there is a Unity project (a real one or a placeholder that makes Gradle and the native binding happy) and register it to Gradle (as instructed by step 2). One more thing to notice is that when you use EAS Build, make sure the Unity project is included in the project archive, i.e., the Unity project is not in your .gitignore if .easignore does not exist, or not in your .easignore if .easignore exists. Otherwise, Gradle will complain again when building with EAS Build because the Unity project is excluded from its working copy of your Expo project.

I've added directly in the included project

android/settings.gradle

include ':unityLibrary'
project(':unityLibrary').projectDir=new File('..(path to)....\\unityLibrary')

android/app/build.gradle (dependencies)

    implementation project(':unityLibrary')
    implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: "*.jar")

and building works fine now.

And?

[GangaBS99]

after adding implementation the error changed to could not find implementation()

[Luluno01]

It sounds like either the path of the implementation is wrong, or the pointed-to unity Android project folder does not exist in your build environment. If you are using EAS, you need to make sure the unity Android project folder is not ignored.

It seems your Unity project export has failed and the arcore_client.aar file is not generated under the folder unityLibrary/libs. You can verify this by checking that folder. In my case, there are 5 files under unityLibrary/libs, namely ARPresto.aar, UnityARCore.aar, arcore_client.aar, unity-classes.jar, and unityandroidpermissions.aar. After exporting, you can "build" from Unity Editor to verify if the exported project itself can build without an error. Alternatively, you can build the exported project via Gradle build command (gradle build or something similar, can't remember).

Okay. So it sounds like some Gradle debugging/hacking to do. As I'm not much a Gradle user, I'm not sure what the root cause is and what the "correct" way is to solve this. What I can suggest is, since it complains about a missing dependency, you can try manually declaring it (by copy-pasting/altering some lines from unityLibrary/build.gradle) before referencing the project :unityLibrary. Not sure if this would work, though.

2: Could not find :arcore_client:. Required by: project :unityLibrary

The error message might indicate the first error is caused by the second error. In summary, the issue you are facing is, you have declared the project :unityLibrary, and Gradle is able to include unityLibrary/build.gradle, but Gradle is not able to find the artifacts required by the project :unityLibrary. According to the Gradle troubleshooting document Declaring repositories you attached, this should be solved by following the instructions in README:

Add into android/build.gradle

allprojects {
  repositories {
    // this
    flatDir {
        dirs "${project(':unityLibrary').projectDir}/libs"
    }
// ...

Given that those artifacts are indeed generated under unityLibrary/libs, I suspect the directive implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: "*.jar") you added may be problematic. You can verify this by adding some debugging output to build.gradle (see https://stackoverflow.com/questions/40878923/in-gradle-how-to-print-out-a-message-in-the-console-event-log).

(Sorry I'm not an Gradle expert. All I can help is to provide some generic debugging suggestions.)

---

Edit:

The directive implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: "*.jar") is indeed problematic. Note that it includes .jar files only (include: "*.jar"). The missing artifacts, however, are .aar files.
