如何使uploadArchives依赖于另一个任务？

Question

我的build.gradle有以下build.gradle ：

afterEvaluate { project ->
  uploadArchives {
    repositories {
      mavenDeployer {
        configuration = configurations.deployerJars
        pom.packaging = "aar"
        pom.groupId = project.CORE_GROUP
        pom.version = project.CORE_VERSION_NAME

        repository(url: "scp://" + project.CORE_MAVEN_URL) {
          authentication(userName: project.uploadUsername, privateKey: project.uploadKeyFile)
        }
      }
    }
  }
}

我希望它取决于以下任务：

task checkProperties << {
  if (!project.hasProperty('uploadUsername')) {
   throw new RuntimeException("Couldn't find uploadUsername property. Did you forget to specify it in ~/.gradle/gradle.properties?")
  } else if (!project.hasProperty('uploadKeyFile')) {
    throw new RuntimeException("Couldn't find uploadKeyFile property. Did you forget to specify it in ~/.gradle/gradle.properties?")
  }
}

我该如何实现？ 如果我写以下内容：

afterEvaluate { project ->
  uploadArchives(dependsOn: checkProperties) {
    repositories {
      mavenDeployer {
        configuration = configurations.deployerJars
        pom.packaging = "aar"
        pom.groupId = project.CORE_GROUP
        pom.version = project.CORE_VERSION_NAME

        repository(url: "scp://" + project.CORE_MAVEN_URL) {
          authentication(userName: project.uploadUsername, privateKey: project.uploadKeyFile)
        }
      }
    }
  }
}

然后我得到以下错误：

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/scottjohnson/Source/core-android/core/build.gradle' line: 61

* What went wrong:
A problem occurred configuring project ':core'.

BUILD FAILED

Total time: 7.68 secs

顺便说一句，我现在要这样做的原因是，如果我只是将检查属性的代码放入uploadArchives任务中，那么即使我运行./gradlew clean build ，它./gradlew clean build检查属性（我不会想要在我的构建服务器上进行，因为它没有实际上传档案的权限。 因此，仅在执行uploadArchives任务时才检查属性的方法也是可以接受的。

Answer 1

也许您可以尝试以下方法：

apply plugin: 'java'

def uploadUsername = project.hasProperty('uploadUsername') ? project['uploadUsername'] : ''
def uploadKeyFile = project.hasProperty('uploadKeyFile') ? project['uploadKeyFile'] : ''

uploadArchives { }

task checkProperties << {
   if (!uploadUsername) {
      throw new RuntimeException("Couldn't find uploadUsername property. Did you forget to specify it in ~/.gradle/gradle.properties?")
   } else if (!uploadKeyFile) {
      throw new RuntimeException("Couldn't find uploadKeyFile property. Did you forget to specify it in ~/.gradle/gradle.properties?")
   }
}

uploadArchives.dependsOn(checkProperties)

在开始时，将读取两个属性并将其分配给两个变量。 如果其中任何一个不存在，则将分配简单的空值。 它不会干扰构建流程。 然后声明uploadArchives依赖于checkProperties 。 如果调用它，则checkProperties将运行并在任何声明的变量为空的情况下引发异常。

关于您的错误消息，您可能会错过将Maven插件应用于build.gradle文件（应用插件：“ maven”）。

我能够部分基于@Opal的评论来弄清楚：

def checkProperties() {                                                         
  if (!project.hasProperty('uploadUsername')) {                                 
   throw new RuntimeException("Couldn't find uploadUsername property. Did you forget to specify it in ~/.gradle/gradle.properties?")
  } else if (!project.hasProperty('uploadKeyFile')) {                           
    throw new RuntimeException("Couldn't find uploadKeyFile property. Did you forget to specify it in ~/.gradle/gradle.properties?")
  }                                                                             
}                                                                               

uploadArchives {                                                                
  repositories {                                                                
    mavenDeployer {                                                             
      configuration = configurations.deployerJars                               
      pom.packaging = "aar"                                                     
      pom.groupId = project.CORE_GROUP                                          
      pom.version = project.CORE_VERSION_NAME                                   
      repository(url: "scp://" + project.CORE_MAVEN_URL) {                      
      }                                                                         
    }                                                                           
  }
