使用 Nexus 的 Android Gradle 库依赖与库依赖 [英] Android Gradle library dependency with library dependency using Nexus

问题描述

我正在将我的项目切换到使用 Gradle 和内部 SonaType Nexus 来托管我的依赖项.我的核心项目依赖于库项目 A，库项目 A 依赖于库项目 B.

I'm switching my project over to using Gradle and an internal SonaType Nexus for hosting my dependencies. My core project depends on library project A and library project A has a dependency on library project B.

我的问题是，一旦我将 LibA 添加到我的主项目中，我就会收到此错误:模块版本 com.example:LibA:1.1 依赖于库，但本身不是库"

My issue is that as soon as I add LibA to my main project I get this error: "Module version com.example:LibA:1.1 depends on libraries but is not a library itself"

使用相同的构建脚本添加具有 jar 依赖项的库项目没有问题.我已经看到人们使用 LOCAL(在项目中)android 库成功地做到了这一点，但没有人使用 maven repos 做到这一点.

I have no issues adding library projects with jar dependencies with the same build script. I have seen people doing this successfully with LOCAL (in the project) android libraries but no one doing it with maven repos.

这是 gradle 中的错误还是我错误地配置了库构建?

Is this a bug in gradle or did I misconfigure the library builds?

核心项目构建

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    maven {
        url "http://localhost:8081/nexus/content/repositories/releases/"
    }

    maven {
        url "http://localhost:8081/nexus/content/repositories/central/"
    }
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19
    }
}

dependencies {
    compile 'com.android.support:support-v4:+'
    compile('com.example:LibA:1.+')
}

LibA 构建

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android-library'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 17

        versionCode = "3"
        versionName = "1.2"
    }

    android {
        sourceSets {
            main {
                manifest.srcFile 'AndroidManifest.xml'
                java.srcDirs = ['src']
                resources.srcDirs = ['src']
                aild.srcDirs = ['src']
                renderscript.srcDirs = ['src']
                res.srcDirs = ['res']
                assets.srcDirs = ['assets']
            }

        }
    }

    repositories {
        mavenCentral()
    }

    dependencies {
        compile ('com.example:LibB:1.+')
    } ...

LibB 构建

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android-library'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 17

        versionCode = "1"
        versionName = "1.0"
    }

    android {
        sourceSets {
            main {
                manifest.srcFile 'AndroidManifest.xml'
                java.srcDirs = ['src']
                resources.srcDirs = ['src']
                aild.srcDirs = ['src']
                renderscript.srcDirs = ['src']
                res.srcDirs = ['res']
                assets.srcDirs = ['assets']
            }

        }
    }

    repositories {
        mavenCentral()
    }

    dependencies {
    } ...

为错误添加 -info 输出.

Adding -info output for the error.

* What went wrong:
A problem occurred configuring project ':GradleTest'.
> Failed to notify project evaluation listener.
   > Module version com.example:LibA:1.+ depends on libraries but is not a library itself

编辑 2:为 LibA 添加我的本地 Maven 上传脚本

Edit 2: Adding my local maven upload script for LibA

apply plugin: 'maven'
apply plugin: 'signing'

group = "com.example"
version = defaultConfig.versionName

configurations {
    archives {
        extendsFrom configurations.default
    }
}

signing {
    required { has("release") && gradle.taskGraph.hasTask("uploadArchives") }
    sign configurations.archives
}


uploadArchives {
    configuration = configurations.archives
    repositories.mavenDeployer {
        beforeDeployment { MavenDeployment deployment -> signing.signPom(deployment) }
        repository(url: sonatypeRepo) {
            authentication(userName: sonatypeUsername,
                    password: sonatypePassword)
        }

        pom.project {
            name 'com-example'
            packaging 'aar'
            description 'none'
            url 'https://internal github link'

            scm {
                url 'scm:git@https://internal github link'
                connection 'git@https://internal github link'
                developerConnection 'git@https://internal github link'
            }

            licenses {
                license {
                    name 'example'
                    url 'example'
                    distribution 'example'
                }
            }

            developers {
                developer {
                    id 'example'
                    name 'example'
                    email 'example'
                }
            }

            groupId "com.example"
            artifactId rootProject.name //LibA
            version defaultConfig.versionName
        }
    }
}

推荐答案

此问题在更高版本的 Gradle 和 Android Gradle 插件中消失了.似乎只是一个早期发布的错误.

This issue has gone away with the later versions of Gradle and the Android Gradle Plugin. Seems to have just been an early release bug.
