gradle命令:

• gradle -v //版本号
• gradle clean //清除build文件夹
• gradle build //检查依赖并打包
• gradle assembleDebug //编译打包Debug包
• gradle assembleRelease //编译打包Release包
• gradle installRelease //打包并安装Release包
• gradle unstallRelease //卸载Release包
• gradle dependencies //查看依赖图表
• gradle clean build -x test //跳过测试编译
• gradle –profile build //分析构建任务
• gradle build –dry-run //编译并不执行任务
• gradle install //安置项目jar包到本地Maven仓库
• gradle tasks //查看Gradle任务
• gradle tasks –all //查看所有Gradle任务
• gradle build –daemon //使用Gradle守护程序(Daemon)
• gradle build –offline //用离线模式运行
• gradle clean build –refresh-dependencies //刷新Gradle依赖缓存

项目中存在的多个module，或者依赖的Library中引用了相同的库，但库的版本不一致。例如主项目中引用的是Glide4.2，但依赖的第三方库中使用的却是Glide3.8。此时需要统一项目中Glide的版本。

在build.gradle中添加如下配置：
configurations.all {
    resolutionStrategy {
        force 'com.github.bumptech.glide:glide:4.2.0'
        force 'com.github.bumptech.glide:compiler:4.2.0'
    }
}

从命令行解析buildType

project.getGradle().addListener(new DependencyResolutionListener() {
  @Override
  void beforeResolve(ResolvableDependencies dependencies) {
  }

  @Override
  void afterResolve(ResolvableDependencies dependencies) {
    def projectPath = dependencies.path.toLowerCase()
    println("projectPath : ")
    dependencies.resolutionResult.allDependencies.each { dependecy ->
      println("depaaaaa: " + dependentComponents.toString())
    }
  }
})

//1. 从命令行中解析出buildType
def currentBuildType = "debug" //debug
gradle.startParameter.taskNames.each({
  String taskNameL = it.toLowerCase();
  if(taskNameL.contains("assemble") || taskNameL.contains("install")) {
    if(taskNameL.contains("debug")) {
      currentBuildType = "debug"
      return;
    } else if(taskNameL.contains("release")) {
      currentBuildType = "release"
      return;
    }else{
      currentBuildType = "debug"
    }
  }
})

applicationVariants.all { variant ->
    variant.packageApplication.outputDirectory =
        new File(project.buildDir.absolutePath + "/outputs/apk")

    variant.outputs.all {
      outputFileName = "linkim.jar"
    }
    variant.getCompileConfiguration().resolutionStrategy {
      // Use Gradle's ResolutionStrategy API
      // to customize how this variant resolves dependencies.
      println("resolutionStrategy : " + variant.buildType.name + ";project name : " + variant)
    }
  }

compile project(':libim',{ pj ->
    //2. 将解析出的buildType设置给library
    pj.ext.buildType = currentBuildType
  })

库中

roject.getGradle().addListener(new DependencyResolutionListener() {
  @Override
  void beforeResolve(ResolvableDependencies dependencies) {
  }

  @Override
  void afterResolve(ResolvableDependencies dependencies) {
    def projectPath = dependencies.path.toLowerCase()
    println("libim projectPath : " + projectPath)
  }
})

def currentBuildType = extensions.extraProperties.has("buildType") ? "${ext.buildType}" : "debug"



if(currentBuildType == "debug"){
    provided rootProject.ext.depsLibs.ljim
  }else{
    provided("com.lianjia.sdk:chatui:2.32.0@aar")
  }
