Gradle 分发ZIP中的多项目渐变重复依赖项

我有一个gradle多项目设置，我希望将所有相关的JAR和输出JAR收集到顶层的ZIP中。我有一些东西在工作，但是我在ZIP文件中找到了重复的东西。我在这本书里找不到任何有用的东西

• 如何删除重复项
• 我还有别的办法吗

结构

./multi-project
./multi-project/build.gradle
./multi-project/settings.gradle
./multi-project/bar
./multi-project/bar/build.gradle
./multi-project/foo
./multi-project/foo/build.gradle

顶级build.gradle

apply plugin: 'java'

allprojects {
  apply plugin: 'java'

  repositories {
    mavenCentral()
  }
}

task buildDist(type: Zip) {
    from subprojects.configurations.compile into 'jars'
    from subprojects.jar.outputs.files into 'jars'
}

格雷德尔酒店

include ':foo'
include ':bar'

foo和bar的低级build.gradle文件（两者相同）

当我从顶层运行gradle:buildDist时，ZIP中有重复项

unzip -l build/distributions/multi-project.zip 

Archive:  build/distributions/multi-project.zip

这是我想到的最好的

• 将所有依赖项解析为文件实例并放入哈希集中
• 包装在gradle.taskGraph.whenReady闭包中，否则过早解析会导致配置在尝试添加依赖项闭包时被锁定

范例

task buildDist(type: Zip) {
    gradle.taskGraph.whenReady { taskGraph ->
      def uniqueFiles = new HashSet()

      uniqueFiles.addAll(subprojects.configurations.compile.resolvedConfiguration.resolvedArtifacts.file)
      uniqueFiles.addAll(subprojects.jar.outputs.files)

      from uniqueFiles into 'jars'

   }
}

Nice one，非常感谢，我知道您参与了

task buildDist(type: Zip) {
    gradle.taskGraph.whenReady { taskGraph ->
      def uniqueFiles = new HashSet()

      uniqueFiles.addAll(subprojects.configurations.compile.resolvedConfiguration.resolvedArtifacts.file)
      uniqueFiles.addAll(subprojects.jar.outputs.files)

      from uniqueFiles into 'jars'

   }
}

task buildDist(type: Zip) {
    into 'jars'
    from { subprojects.configurations.runtime }
    from { subprojects.jar }
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE
}
