[SDK] Could not resolve all dependencies for org.matrix.android:matrix-android-sdk2

[cryptodev100]

Description

Hi,

I tried to integrate the matrix-android-sdk into an existing Android-app by adding the following line to my app-module's build.gradle.kts:

implementation("org.matrix.android:matrix-android-sdk2:1.3.2")

However, my build fails with the following output:

Could not resolve all task dependencies
Could not find com.github.Zhuinden:realm-monarchy:0.7.1.
Searched in the following locations:

Possible solution:

• Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

As we can see, the missing dependencies are com.github.Zhuinden:realm-monarchy:0.7.1 and org.matrix.android:matrix-android-sdk2:1.3.2.
Both of these missing dependencies are declared in the sdk's build.gradle as follows: https://github.com/matrix-org/matrix-android-sdk2/blob/develop/matrix-sdk-android/build.gradle

So my question is: Am I missing to declare some repositories in my top-level build.gradle?
Where are we supposed to find those Maven-dependencies?

I was able to resolve the issue by adding the following to my top-level build.gradle.kts:

allprojects {
    repositories {
        maven {
            url = uri("https://jitpack.io")
            content {
                // Use this repo only for olm library
                includeGroupByRegex ("org\\.matrix\\.gitlab\\.matrix-org")
                // And also for FilePicker
                includeGroupByRegex ("com\\.github\\.jaiselrahman")
                // And monarchy
                includeGroupByRegex ("com\\.github\\.Zhuinden")
                // And ucrop
                includeGroupByRegex ("com\\.github\\.yalantis")
                // JsonViewer
                includeGroupByRegex ("com\\.github\\.BillCarsonFr")
                // PhotoView
                includeGroupByRegex ("com\\.github\\.chrisbanes")
                // PFLockScreen-Android
                includeGroupByRegex ("com\\.github\\.vector-im")
                // DraggableView
                includeGroupByRegex ("com\\.github\\.hyuwah")

                // Chat effects
                includeGroupByRegex ("com\\.github\\.jetradarmobile")
                includeGroupByRegex ("nl\\.dionsegijn")

                // Voice RecordView
                includeGroupByRegex ("com\\.github\\.Armen101")
            }
        }
        // other repositories come here
   }
}

I took this from the top-level build.gradle in this monorepo: https://github.com/vector-im/element-android/blob/develop/build.gradle
Nevertheless, I think that this should be added to the documentation for all sdk-only-consumers.

This should not be necessary, we do not do that for instance in the sample app

Sometimes we have issue to get org.matrix.gitlab.matrix-org:olm, this is maybe the root cause. We are working to get ride of this issue, and this is tracked by https://gitlab.matrix.org/matrix-org/olm/-/issues/5

glad to hear your issue is resolved, it sounds like you were missing the jitpack repository

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
}
