I'm developing an Android Bluetooth plugin for Unity using Kotlin. I included the .aar
file of my Kotlin library (which works perfectly in an app running in Android Studio), and since I was getting some dependency errors in runtime, I started using the Android Dependency Resolver plugin.
I started by adding the dependencies that my library had on its .gradle
file:
dependencies {
implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'com.google.android.material:material:1.4.0'
// For Kotlin Coroutines
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.5.2'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
To my library's *Dependencies.xml
, as instructed here by the Dependency Resolver:
<dependencies>
<androidPackages>
<repositories>
<repository>https://repo.maven.apache.org/maven2</repository>
</repositories>
<androidPackage spec="androidx.appcompat:appcompat:1.4.0">
<androidSdkPackageIds>
<androidSdkPackageId>extra-google-m2repository</androidSdkPackageId>
</androidSdkPackageIds>
<repositories>
<repository>https://maven.google.com</repository>
</repositories>
</androidPackage>
<androidPackage spec="androidx.core:core-ktx:1.7.0">
<androidSdkPackageIds>
<androidSdkPackageId>extra-google-m2repository</androidSdkPackageId>
</androidSdkPackageIds>
<repositories>
<repository>https://maven.google.com</repository>
</repositories>
</androidPackage>
<androidPackage spec="org.jetbrains.kotlinx:kotlinx-coroutines-android:1.5.2">
<androidSdkPackageIds>
<androidSdkPackageId>extra-google-m2repository</androidSdkPackageId>
</androidSdkPackageIds>
<repositories>
<repository>https://maven.google.com</repository>
</repositories>
</androidPackage>
</androidPackages>
</dependencies>
The Dependency Resolver works and does it's job, but then when I try to compile the project I get the error:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':launcher:processReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

There was a bug with the Dependency Resolver, you can track down the related issue here, as well as a workaround I found in the mean time. Remember to switch off Enable Resolution On Build
under Assets -> External Dependency Manager -> Android Resolver -> Settings
.
