Question

我有一个gradle多项目设置，我希望将所有依赖和输出JAR收集到顶层的ZIP中。我有一些工作，但我最终在ZIP文件中重复。我在official documentation on multi project setups

中找不到任何有用的内容

如何删除重复项？
我应该采取另一种方法吗？

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'
}

Settings.gradle

include ':foo'
include ':bar'

foo和bar的低级build.gradle文件（两者都相同）

dependencies {
   compile 'org.springframework:spring-beans:4.1.0.RELEASE'
}

当我运行gradle：来自顶层的buildDist时，ZIP有重复

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

Answer 1

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

要查看特定Gradle任务类型的所有配置选项，请参阅Gradle Build Language Reference。

Answer 2

我最好提出

解析所有依赖项到File实例并放入HashSet。
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关闭时被锁定。

实施例

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'

   }
}

多项目在分发ZIP中重复依赖关系
