Pom file is missing transitive dependencies such as Google support libraries

[johnjohndoe]

I maintain an Android library project where the dcendents.android-maven plugin is used to deploy to mavenLocal while developing and the gradle-nexus-plugin is used to publish to an internal Nexus repository.

The following Gradle configuration is used:

Top level build.gradle

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:2.1.3"
        classpath "com.neenbedankt.gradle.plugins:android-apt:1.8"
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

Library build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "com.github.dcendents:android-maven-gradle-plugin:1.4.1"
        classpath "com.bmuschko:gradle-nexus-plugin:2.3.1"
    }
}

apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'
apply plugin: 'com.bmuschko.nexus'


group = project.groupId
version = project.versionName

android {
    compileSdkVersion Integer.parseInt(project.compileSdkVersion)
    buildToolsVersion project.buildToolsVersion

    defaultConfig {
        minSdkVersion Integer.parseInt(project.minSdkVersion)
        targetSdkVersion Integer.parseInt(project.targetSdkVersion)
        versionCode Integer.parseInt(project.versionCode)
        versionName project.versionName
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile "com.android.support:design:$project.supportVersion"
    compile "com.android.support:cardview-v7:$project.supportVersion"
}

modifyPom {
    project {
        name 'AndroidLibrary'
        description 'An Android library'
        url 'https://stash.company.lan/projects/repos/androidlibrary'
        inceptionYear '2016'

        scm {
            url 'https://stash.company.lan/projects/repos/androidlibrary'
            connection 'scm:https://stash.company.lan/scm/androidlibrary.git'
            developerConnection 'scm:ssh://git@stash.company.lan/androidlibrary.git'
        }
    }
}

extraArchive {
    sources = true
    tests = true
    javadoc = true
}

nexus {
    sign = true
    repositoryUrl = "http://internal/repository/company-internal-releases/"
    snapshotRepositoryUrl = "http://internal/repository/company-internal-snapshots/"
}

As you can see from the configuration the library itself depends on Google support libraries.

The problem

When integrating the library in an application project I noticed that the transitive dependencies of the library (speaking of the Google support libraries) can not be found by Gradle. This only happens when I reference mavenLocal(). When I reference the Nexus repository everything is fine.

When I compare the pom files from mavenLocal() and Nexus it can be seen that the one deployed to mavenLocal() is missing the transitive dependencies.

@dcendents Any comment?

[dcendents]

Hi,

Sorry I lack personal time right now to work on this project and I'm not currently working on Android projects at work either at the moment so it's a bit hard to test all the different issues that are reported.

I need to build some test project(s) to cover all the different scenarios and I plan to work on that next.

Otherwise concerning your particular issue I will need to review the gradle-nexus-plugin to understand what it is doing differently.

I hope to come back to you soon.

Cheers

[johnjohndoe]

Thank you for taking time to respond. I respect this and appreciate your work. If I have time myself I will try to digg into the plugin(s) myself.

[Onlinedispatcher]

Did you find any solution for that? Having the same issue...

[johnjohndoe]

@Onlinedispatcher Sorry, but I did not investigate further.
