Android : resolve external dependencies over Artif

So we are currently working on the migration of ant building/publishing scripts for Android projects to the new Android Gradle build system.

Our projects generally relies on both internal and third-party libraries. The internal libraries have been published on Artifactory repositories and now I'm struggling to resolve the dependencies over them.

buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }

        maven{
            url 'http://dl.bintray.com/jfrog/jfrog-jars'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
        classpath(group: 'org.jfrog.buildinfo', name: 'build-info-extractor-gradle', version: '2.1.0')
    }
}
apply plugin: 'android'
apply plugin: 'artifactory'

artifactory {
    contextUrl = 'my_artifactory_url'

    resolve {
        repository {
            repoKey = 'libs-snapshot'
            maven = true
        }
    }
}

dependencies {
    compile files('libs/android-support-v4.jar')
    compile(group: 'groupId', name: 'artifact1Id', version: 'artifact1Version')
    compile(group: 'groupId', name: 'artifact2Id', version: 'artifact2Version')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

I basically used built-in options in Artifactory to generate the artifactory{} section and the two compile() lines. But I'm having this error when trying to build (and I keep having it whatever minor changes I tried) :

I'm probably missing something big, but as a newcomer to Gradle, Maven & Artifactory, I feel kinda lost for the moment. Can someone enlighten me or perhaps tell me how can I get more precise informations on the problem (I tried the --debug and --info, --s and --S options and it was not very helpful). The initial exception is always :

Caused by: org.gradle.api.internal.artifacts.ivyservice.ModuleVersionNotFoundException: Could not find groupId:artifact1Id:artifact1Version.

The 'gradle refresh-dependencies --info' command didn't give more useful information. What is very troubling though is that the debug traces never mentionned the contextUrl I provided. Instead I got the following (which, I suppose, is not what I should have) :

回答1:

you have double checked that "groupId:artifact2Id:artifact2Version" is in your artifactory repository? or do you accidently rely on a variable here instead of the string?

cheers, René

回答2:

As @noamt said the only thing wrong was the fact I was not declaring a repositories {} section that actually allows the connection with Artifactory. I am still a bit confused why this is not directly handled by the artifactory {} section but at least it is working now.

回答3:

I've found that gradle by default picks up the android sdk repository:

C:\Users\YOUR_USER\android-sdks\extras\android\m2repository

Instead of:

C:\Users\YOUR_USER\.m2\repository

When looking for artifacts but the later when downloading them. Do a comparison and check if they are being downloaded in the second one.
