gradle - gradle副本包括关闭不起作用

Question

Gradle copySpec包含闭包不起作用:

def fileList = ["hello/world.xml"]

task foo(type: Copy) {
  from (zipTree("/path/a.zip")) {
     include { elem ->
         fileList.contains(elem.path)
     }
  }

}

a.zip包含“hello / world.xml”。

信息:

Skipping task 'foo' as it has no source files and no previous output files.

copySpec闭包需要与复制任务一起使用。
您的代码只是复制任务，需要将目标复制到其中。

您的代码应更像这样:

def fileList = ["hello/world.xml"]

def filesToCopy = copySpec {
    from (zipTree("/path/a.zip")) {
        include { elem ->
            fileList.contains(elem.path)
        }
    }
}

task foo(type: Copy) {
    into 'build/target/docs'

    with filesToCopy
}
