Question

我在从maven centeral存储库加载依赖项时遇到问题我有一个图书馆项目，我的不同客户使用我的图书馆。我的库依赖于GoolgePlayService以及appcompat-v7。最近我开始使用Gradle而不是ant。所以我使用了andoird-library插件，并将我的library.aar文件推送到我的本地依赖项。现在在我的TestApp中，我从本地maven加载了aar文件，但它没有从maven中央存储库加载depenecy文件。

以下是我的build.gradle文件

申请插件：'android-library'

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.0'
    }
}

apply plugin: 'maven'

version = "1.0.0_Build-1"
group = "com.sflibrary"

 repositories {
    mavenCentral()
 }

dependencies {
     compile ('com.google.android.gms:play-services:4.0.30') {
        exclude module: 'support-v4'
     }
     compile 'com.android.support:appcompat-v7:+'
     compile files('libs/android-support-v4.jar')
     compile files('libs/libGoogleAnalyticsServices.jar')
}


android {
    buildToolsVersion "17.0.0"
    compileSdkVersion 17
    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 17
    }

    lintOptions {
        abortOnError false
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']

            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']

            renderscript.srcDirs = ['src']

            res.srcDirs = ['res']
            assets.srcDirs = ['assets']

        }


        instrumentTest.setRoot('tests')
    }

}

uploadArchives {
  repositories {
    mavenDeployer {
      repository(url: "file://${System.env.HOME}/.m2/repository/")
    }
  }
}

当我运行“gradle uploadArchives”时，它可以上传到我的本地mavel存储库，其pom文件如下所示

<?xml version="1.0" encoding="UTF-8"?>

      <version>+</version>  
      <scope>compile</scope>  
    </dependency>  
  </dependencies>  
</project>

以下是我的TestApp build.gradle文件 apply plugin: 'android' apply plugin: 'maven'



buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {

    compile('com.snapfish:library:1.0.0_Build-1@aar')
    compile files('libs/httpmime-4.2.1.jar')
}


android {
    buildToolsVersion "17.0.0"
    compileSdkVersion 17
    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 17
    }

    lintOptions {
        abortOnError false
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']

            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']

            renderscript.srcDirs = ['src']

            res.srcDirs = ['res']
            assets.srcDirs = ['assets']

        }
        instrumentTest.setRoot('tests')
    }

}


I am getting below error

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}

repositories {
    mavenCentral()
    mavenLocal()
}

dependencies {

    compile('com.snapfish:library:1.0.0_Build-1@aar')
    compile files('libs/httpmime-4.2.1.jar')
}


android {
    buildToolsVersion "17.0.0"
    compileSdkVersion 17
    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 17
    }

    lintOptions {
        abortOnError false
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']

            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']

            renderscript.srcDirs = ['src']

            res.srcDirs = ['res']
            assets.srcDirs = ['assets']

        }
        instrumentTest.setRoot('tests')
    }

}

然而，如果我再次在TestApp build.gradle文件依赖项部分中指定我的库依赖项，它工作正常。这意味着它从本地maven存储库加载我的library.aar文件，但是没有从maven中央存储库加载appcompat-v7。

我不知道我在这里做了什么错误。

Answer 1

就我而言，我能够通过以下方式让它工作：

将aar文件上传到我的Nexus
将我的Nexus添加到所有项目：存储库：maven：url

在依赖项上指定transitive = true，如：

compile('com.snapfish:library:1.0.0_Build-1@aar'){
    transitive=true
}

如果我正在使用SNAPSHOT Maven版本，我还必须设置：

configurations.all {
    // check for updates every build (If a version number ends in -SNAPSHOT it is implicitly changing when looking for it in a maven repository)
    resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}

Answer 2

目前，gradle不处理传递依赖

有关详细信息，请参阅此答案：https://stackoverflow.com/a/20530181/115145

“仅限配置为的项目的存储库声明目前解决的问题也被考虑在内，即使在传递时也是如此涉及依赖性。“

Android aar文件所需的依赖项未加载
