Gradle could not resolve dependency from artifactory

Question

I'm trying to build an android-library (MyLib1), which depends on another android-library (MyLib2) in gradle and jenkins. I'm a little bit desperated, because I think my gradle files and settings are ok.

I successfully published the first android-library to artifactory. In artifactory, I can see the following dependency declaration:

compile(group: 'MyGroup', name: 'MyLib1', version: '1.0', ext: 'aar')

I pasted this dependency declaration into my secound build.gradle:

buildscript {
  repositories {
    maven { url "http://localhost:8081/artifactory/myvirtualrepository" }
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:0.6.+'
    classpath(group: 'org.jfrog.buildinfo', name: 'build-info-extractor-gradle', version: '2.2.0')
  }
}
(...)
dependencies {
  compile (group: 'MyGroup', name: 'MyLib1', version: '1.0', ext: 'aar')
  (...)
}

But gradle cannot find the android-library (MyLib1)? I get the following error:

 * What went wrong:
 15:50:50.110 [ERROR] [org.gradle.BuildExceptionReporter] A problem occurred configuring root project 'workspace'.
 15:50:50.111 [ERROR] [org.gradle.BuildExceptionReporter] > Failed to notify project evaluation listener.
 15:50:50.111 [ERROR] [org.gradle.BuildExceptionReporter]    > Could not resolve all dependencies for configuration ':_DebugCompile'.
 15:50:50.112 [ERROR] [org.gradle.BuildExceptionReporter]       > Could not find MyGroup:MyLib1:1.0.
 15:50:50.113 [ERROR] [org.gradle.BuildExceptionReporter]         Required by:
 15:50:50.113 [ERROR] [org.gradle.BuildExceptionReporter]             MyGroup:workspace:1.0

How can I manage to resolve my android-library? Is there a way to "debug" dependencies?

Note: "MyGroup" is a part from "myvirtualrepository"

Answer 1

There is an easy way to debug Artifactory resolution - the trace command.

In your case you should run http://localhost:8081/artifactory/myvirtualrepository/MyGroup/MyLib1/1.0/MyLib1-1.0.jar?trace

The output is straighforward, but if you need additional help, you can add the output to the question and we'll figure that out.

So, regarding your trace - it shows that the artifact was found and successfully downloaded. Can you download the artifact from the virtual repo using your browser? Browsing to http://localhost:8081/artifactory/myvirtualrepository/MyGroup/MyLib1/1.0/MyLib1-1.0.aar?

And what about the local repo (http://localhost:8081/artifactory/mylocalrepository/MyGroup/MyLib1/1.0/MyLib1-1.0.aar)?
