How can I make uploadArchives dependent on another task?

问题

I have the following in my 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)
        }
      }
    }
  }
}

And I want it to be dependent on the following task:

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?")
  }
}

How can I achieve this? If I write the following:

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)
        }
      }
    }
  }
}

Then I get the following error:

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

BTW, the reason I want to do this is that right now, if I just put the code that checks the properties into the uploadArchives task, then even if I run ./gradlew clean build, it checks the properties (which I don't want to happen on my build server, since it doesn't have permission to actually upload the archives). Thus, a method that would check the properties only when the uploadArchives task is executed would also be acceptable.

回答1:

Maybe You can try something like:

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)

At the beginning both properties are read and assigned to two variables. If any of them not exists, simple empty value will be assigned. It doesn't interfere with build flow. Then uploadArchives is declared to depend on checkProperties. If it's invoked checkProperties will be run and throw exception if any of declared variables is empty.

回答2:

Regarding to your error message you might miss to apply the maven plugin to your build.gradle file (apply plugin: 'maven').

See: https://discuss.gradle.org/t/configure-mavendeployer-programmatically/16956/2

I was able to figure it out based in part on @Opal's comment:

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 {

    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) {                      
      }                                                                         
    }

gradle.taskGraph.beforeTask { Task aTask ->

}
