Tool Time-Android Studio发布项目到Maven仓库

Tools 2017-02

新建Android Studio项目

新建Studio项目，一般我们需要发布到Maven仓库的Module都带有如下性质：

apply plugin: 'com.android.library'

目前新建的Android项目都是规整的目录结构如下：

而对应生成的build.gradle一般如下：

apply plugin: 'com.android.library'
android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"
    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.1.0'
}

如果项目是直接从Eclipse转为Studio的话会多出如下部分

sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            jniLibs.srcDirs = ['libs']
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')
        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }

上面会指定将原先不规则的目录结构转换为规则的Studio结构，下面上传Maven配置的时候会用到。

配置Gradle

无论是上面哪一种build.gradle文件，我们需要将下面的配置添加到该文件中

apply plugin: 'maven'
android {
    task sourcesJar(type: Jar) {
        classifier = 'sources'
        from android.sourceSets.main.java.srcDirs
    }
    artifacts {
        archives sourcesJar
    }
    uploadArchives {
        repositories {
            mavenDeployer {
                repository(url: "http://127.0.0.1:8081/nexus/content/repositories/releases/") {
                    authentication(userName: 'admin', password: 'admin123')
                }
                snapshotRepository(url: "http://127.0.0.1:8081/nexus/content/repositories/snapshots/") {
                    authentication(userName: 'admin', password: 'admin123')
                }
                pom.groupId = 'com.aspect.plugin'
                pom.artifactId = 'deploy'
                pom.version = '1.0.0'
                pom.project {
                    name 'Android Library'
                    packaging 'aar'
                }
            }
        }
    }
}

gradlew uploadArchives

接下来运行./gradlew uploadArchives即可，运行成功以后，检查maven仓库中已经出现了aar文件

其对外的访问地址

使用

上面maven上传的aar如何使用？

在项目级别的build.gradle配置

buildscript {
    repositories {
        jcenter()
        maven { url "http://127.0.0.1:8081/nexus/content/groups/public/" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        maven { url "http://127.0.0.1:8081/nexus/content/groups/public/" }
        jcenter()
    }
}

然后再具体的module级别的gradle中需要引用的地方配置即可

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.aspect.plugin:deploy:1.0.0'
}

sync 一下即可。
