Maven Repository on Github not downloading transitive dependencies

Question

I have created a maven repository and uploaded it to Github. When I add it as a dependency to a sample project, the gradle sync completes successfully. But when I try to run the app, it crashes with a java.lang.NoClassDefFoundError.

Link to repository: https://github.com/rjain90/sdk

Sample project code:

Project build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext{
        kotlin_version = '1.3.20'
        realm_version = '5.8.0'
    }
    repositories {
        google()
        jcenter()
        maven { url "https://raw.githubusercontent.com/rjain90/sdk/master/" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "io.realm:realm-gradle-plugin:$realm_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://raw.githubusercontent.com/rjain90/sdk/master/" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

ext{
    lifecycle_version = '2.0.0'
    android_support_version = '1.1.0-alpha01'
    legacy_support_version = '1.0.0'
    constraint_version = '1.1.3'

Why do you adding your "repository" (even, maybe not a repository) at the `repository` section? What you need may be a https://jitpack.io/. — Geno Chen, Mar 11 '19 at 09:56
@GenoChen I tried using Jitpack but ran into the same problem — Rishabh Jain, Mar 11 '19 at 17:53
What is the `NoClassDefError` generated for? For your library? — Geno Chen, Mar 11 '19 at 17:55
Besides, "the same problem" may even not precise: Maybe throwing for different place. — Geno Chen, Mar 12 '19 at 03:26
The error is the same in all cases: NoClassDefFoundError: Failed resolution of: Lokhttp3/internal/Platform — Rishabh Jain, Mar 12 '19 at 08:03
Is adding `implementation com.squareup.okhttp3:logging-interceptor:3.10.0` in your module `build.gradle`'s `dependencies` solve the issue? — Geno Chen, Mar 12 '19 at 08:13
After adding this, I get the same error but for the next dependency and so on — Rishabh Jain, Mar 12 '19 at 11:45

For GitHub hosted, you can use https://jitpack.io as a Maven repository.

Add maven { url 'https://jitpack.io' } into the project build.gradle's allprojects -> repositories block, then in your module build.gradle, add a dependency implementation 'com.github.rjain90:sdk:0.0.17', for example.

However, your two releases are both containing build errors. Solve them first.

I've removed the errors and tried again with Jitpack but it still doesn't work. – Rishabh Jain Mar 13 '19 at 10:08
@RishabhJain Did you "doesn't work" with `ERROR: Failed to resolve: Android-SDK-Core-Source:coresdk:unspecified`? – Geno Chen Mar 13 '19 at 10:53
Yes and I tried to resolve it by using implementation 'com.github.rjain90:sdk:0.0.17@aar' but ran into the NoClassDefFoundError again – Rishabh Jain Mar 14 '19 at 08:27
Yes. You can use `implementation 'com.github.rjain90:sdk:1.0'`, then you will found your SDK has the dependency `com.estimote:sdk:1.0.3` which depends on `Android-SDK-Core-Source:coresdk:unspecified` which throws the error. After you found where the `Android-SDK-Core-Source:coresdk:unspecified` is, the question is solved. – Geno Chen Mar 14 '19 at 15:29
As of [my search](https://github.com/Estimote/Android-SDK#introduction), "All the proximity monitoring features of this SDK have been deprecated and are no longer supported. Instead, we strongly recommend [Estimote Proximity SDK](https://github.com/Estimote/Android-Proximity-SDK) for Android powered by Estimote Monitoring. ", which have no dependency problems as of the [Maven said](https://mvnrepository.com/artifact/com.estimote/proximity-sdk/1.0.4). – Geno Chen Mar 14 '19 at 16:01
Conclusion: At the `pom.xml` of your SDK, modify `com.estimote`'s `artifactId` from `sdk` to `proximity-sdk`, and use the newest version `1.0.4`, then let Jitpack rebuild your SDK, then you will probably successfully use your SDK in your project. – Geno Chen Mar 14 '19 at 16:04
@RishabhJain The same error with what kind of detail? :-( – Geno Chen Mar 19 '19 at 12:23
