android - Artifact 组装后如何运行shell脚本？

Question

我想运行任务 wsUpload，在 assembleMinAPI16ProdRelease 完成 Artifact 组装后运行 shell 脚本将 Artifact 上传到公司服务器。

从此开始:

afterEvaluate {
  task wsUpload(type: Exec, dependsOn: assembleMinAPI16ProdRelease) {
    def localPropertiesFile = rootProject.file("local.properties");
    def localProperties = new Properties()
    localProperties.load(new FileInputStream(localPropertiesFile))
    def WORK_EMAIL = localProperties['WORK_EMAIL']
    commandLine '../scripts/ws_upload.sh'
    args = [rootProject.ext.VERSION_CODE, WORK_EMAIL]
    println("wsUpload start ")
    commandLine '../scripts/ws_upload.sh'
    //      args = [rootProject.ext.VERSION_CODE, WORK_EMAIL]
    println("wsUpload end")
  }

  assembleMinAPI16ProdRelease.doLast {
    println("-------------------------------------")
    println("---------------DO LAST---------------")
    println("-------------------------------------")
    crashlyticsUploadDistributionMinAPI16ProdRelease.execute()
  }

}

但它在 assembleRelease 完成之前运行。然后我尝试了这个 answer

task wsUpload(type: Exec) {
  def localPropertiesFile = rootProject.file("local.properties");
  def localProperties = new Properties()
  localProperties.load(new FileInputStream(localPropertiesFile))
  def WORK_EMAIL = localProperties['WORK_EMAIL']
  commandLine '../scripts/ws_upload.sh'
  args = [rootProject.ext.VERSION_CODE, WORK_EMAIL]
  println("wsUpload start ")
  doLast {
    exec {
      commandLine '../scripts/ws_upload.sh'
      args = [rootProject.ext.VERSION_CODE, WORK_EMAIL]
      println("wsUpload end")
    }
  }
}

afterEvaluate {

  assembleMinAPI16ProdRelease.doLast {
    println("-------------------------------------")
    println("---------------DO LAST---------------")
    println("-------------------------------------")
    crashlyticsUploadDistributionMinAPI16ProdRelease.execute()
  }
  assembleMinAPI16ProdRelease.doLast {
    wsUpload.execute()
  }
}

给我留下了 > java.lang.NullPointerException(没有错误信息)
然后我尝试将整个 swUpload 设置为 doLast

task wsUpload(type: Exec) << {
  def localPropertiesFile = rootProject.file("local.properties");
  def localProperties = new Properties()
  localProperties.load(new FileInputStream(localPropertiesFile))
  def WORK_EMAIL = localProperties['WORK_EMAIL']
  commandLine '../scripts/ws_upload.sh'
  args = [rootProject.ext.VERSION_CODE, WORK_EMAIL]
  println("wsUpload start ")
  commandLine '../scripts/ws_upload.sh'
  args = [rootProject.ext.VERSION_CODE, WORK_EMAIL]
  println("wsUpload end")
}

出现错误:

Execution failed for task ':app:wsUpload'.
> execCommand == null!

Answer 1

首先，您需要以正确的方式定义一个任务(阅读关于 配置 与 执行 在 gradle 中)，这将是:

task wsUpload(type: Exec) {
  def localPropertiesFile = rootProject.file("local.properties");
  def localProperties = new Properties()
  localProperties.load(new FileInputStream(localPropertiesFile))
  def WORK_EMAIL = localProperties['WORK_EMAIL']
  commandLine '../scripts/ws_upload.sh'
  args [rootProject.ext.VERSION_CODE, WORK_EMAIL]
}

现在您需要定义任务之间的执行顺序依赖关系 - 切记永远不要直接在任务实例上调用 execute()!

我想 assembleMinAPI16ProdRelease 和 crashlyticsUploadDistributionMinAPI16ProdRelease 都是动态任务(在项目评估后创建)所以在 afterEvaluate 中定义依赖关系是明智的> 阻止:

afterEvaluate {
  crashlyticsUploadDistributionMinAPI16ProdRelease.dependsOn assembleMinAPI16ProdRelease
  crashlyticsUploadDistributionMinAPI16ProdRelease.mustRunAfter assembleMinAPI16ProdRelease
  wsUpload.dependsOn crashlyticsUploadDistributionMinAPI16ProdRelease
  wsUpload.mustRunAfter crashlyticsUploadDistributionMinAPI16ProdRelease
}

为什么 mustRunAfter 和 dependsOn 都有？不仅要定义依赖关系，还要定义正确的执行顺序。现在您应该能够运行 gradle wsUpload 并且一切正常。

如果您想运行 assembleMinAPI16ProdRelease 并上传 Artifact ，则应使用 finalizedBy:

afterEvaluate {
   assembleMinAPI16ProdRelease.finalizedBy crashlyticsUploadDistributionMinAPI16ProdRelease
   crashlyticsUploadDistributionMinAPI16ProdRelease.finalizedBy wsUpload
}

请注意，由于我不是 Android 开发人员，我无法正确测试它 - 所以如果它不起作用，请在投反对票之前告诉我 ;)
