gradle整理

1. gradlew 常用命令整理

• gradlew -v 版本号
• gradlew clean 清除工程目录下的build文件夹
• gradlew build 检查依赖并编译打包

这里注意的是 gradlew build 命令把debug、release环境的包都打出来，如果正式发布只需要打Release的包，该怎么办呢，下面介绍一个很有用的命令 assemble, 如

• gradlew assembleDebug(缩写： gradlew aD) 编译并打Debug包
• gradlew assembleRelease(缩写： gradlew aR) 编译并打Release的包

还有打渠道包，如百度 gradlew assembleBaiduRelease 编译并打Release的百度包

除此之外，assemble还可以和productFlavors结合使用,比如定义了 installRelease ，uninstallRelease 两个productFlavors，则可以如下命令：

• gradlew installRelease(缩写： gradlew iR) Release 模式打包并安装
• gradlew uninstallRelease 卸载Release模式包

2. gradlew compile优化

1. gradlew aR –daemon –parallel(交叉依赖不能用这个) -x lint -x test(去掉lint test任务) –offline(使用本地缓存)

2. 减少module的直接依赖，改用引用aar

3. uploadArchives

   1. 发布所有module: gradlew uploadArchives

   2. 发布单个module: gradlew :module_name:uploadArchives

   3. 上传配置：

      //1. 在项目根目录创建maven_push.gradle文件
      apply plugin: 'maven'
      apply plugin: 'signing'
            
      configurations {
          deployerJars
      }
            
      repositories {
          mavenCentral()
      }
            
      // 判断版本是Release or Snapshots
      def isReleaseBuild() {
          return !VERSION.contains("SNAPSHOT");
      }
            
      // 获取仓库url
      def getRepositoryUrl() {
          return isReleaseBuild() ? RELEASE_URL : SNAPSHOT_URL;
      }
            
      uploadArchives {
          repositories {
              mavenDeployer {
                  beforeDeployment {
                      MavenDeployment deployment -> signing.signPom(deployment)
                  }
            
                  pom.version = VERSION
                  pom.artifactId = ARTIFACT_ID
                  pom.groupId = GROUP_ID
                  pom.packaging = 'aar'
            
                  repository(url: getRepositoryUrl()) {
                      authentication(userName: NAME, password: PASSWORD) // maven授权信息
                  }
              }
          }
      }
            
      // 进行数字签名
      signing {
          // 当 发布版本 & 存在"uploadArchives"任务时，才执行
          required { isReleaseBuild() && gradle.taskGraph.hasTask("uploadArchives") }
          sign configurations.archives
      }
            
      //2. 在gradle.properties中配置常量：
      RELEASE_URL=http://www.example.com/
      NAME=admin
      PASSWORD=admin123
            
      //3. 在对应的module中的build.gradle中加入
      apply from: '../maven_push.gradle'
      

3. gradle 常用配置模板
