gradle - 分布ZIP中的多项目Gradle重复依赖项

Question

我有一个gradle多项目设置，我希望将其所有依赖项和输出JAR收集到顶层的ZIP中。我有一些工作，但是最终在ZIP文件中出现了重复项。我在official documentation on multi project setups中找不到任何有用的东西

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的较低级别的build.gradle文件(两者相同)

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

当我从顶层运行gradle:buildDist时，ZIP有重复项

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
}
