gradle检测依赖的脚本

打正式包的时候，一般不允许sdk使用snapshot版本来封板，打封板包的时候如果检测到有snapshot依赖，直接退出打包。下面是依赖检测的脚本，免费贡献给大家参考。

gradle.projectsEvaluated{
  //收集项目的直接依赖信息
  def extension_dep_check = project.extensions.getByName("android")
  extension_dep_check.applicationVariants.all { variant ->
    println(variant.name) //debug、release

    def task = project.tasks.create("checkSnapshot" + variant.name.capitalize())
    task.doFirst{
      Set deps = new HashSet<>()
      project.rootProject.buildscript.configurations.classpath.dependencies.each { dep ->
        if (dep.version != null && dep.group != null && (dep.version.endsWith('-SNAPSHOT') || dep.version.endsWith('+'))) {
           deps.add("${dep.group}:${dep.name}:${dep.version}" + '\r\n')
         }
      }
     //这里检测的是Compile的依赖，要想检测runtime依赖，可以改成RuntimeClasspath
      def configuration = project.configurations."${variant.name}CompileClasspath"
      configuration.resolvedConfiguration.lenientConfiguration.allModuleDependencies.each {
        parse_snapshot_dep(it,deps)
      }
   
     //kapt依赖检测
      def kapt_configuration = project.configurations."kapt${variant.name.capitalize()}"
      kapt_configuration.resolvedConfiguration.lenientConfiguration.allModuleDependencies.each {
        parse_snapshot_dep(it,deps)
      }

      File dir = new File(project.projectDir.absolutePath + "/dependencies")
      if(!dir.exists()){
        dir.mkdir()
      }
      def inputFile = new File(dir.absolutePath, "dependencies-snapshot.txt")
      if(inputFile.exists()){
        inputFile.delete()
      }
      inputFile.createNewFile()
      deps.each {
        inputFile.append(it)
      }
    }
    task.group = "check"
    task.dependsOn variant.getPreBuildProvider().get()
  }
}


  def void parse_snapshot_dep(dependency, deps){
    def identifier = dependency.module.id

      if (identifier.version != "null" && identifier.version != "unspecified"
          && (identifier.version.endsWith('-SNAPSHOT') || identifier.version.endsWith('+'))) {
        deps.add("${identifier.group}:${identifier.name}:${identifier.version}" + '\r\n')
      }

    if(dependency.children != null && dependency.children.size() > 0){
      dependency.children.each{
        parse_snapshot_dep(it, deps)
      }
    }
  }
