跳过任务，因为它没有源文件，也没有以前的输出文件

Question

这是我的 build.gradle，它有三个任务（一个用于下载 zip，一个用于解压缩，另一个用于执行 sh 文件）。这些任务相互依赖。我正在使用 Gradle 6。因为这些是依赖任务，所以我使用了以下命令：

gradlew C

我收到错误：

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

build.gradle:

task A {
    description = 'Rolls out new changes'
    doLast {
        def url = "https://${serverName}/xxx/try.zip"
        def copiedZip = 'build/newdeploy/try.zip'
        logger.lifecycle("Downloading $url...")
        file('build/newdeploy').mkdirs()
        ant.get(src: url, dest: copiedZip, verbose: true)
    }
}
          
task B (type: Copy, dependsOn: 'A') {
    doLast {
        def zipFile = file('build/newdeploy/try.zip') 
        def outputDir = file("build/newdeploy")
        from zipTree(zipFile)
        into outputDir
    }
}

task C (type: Exec, dependsOn: 'B') {
    doLast {
       workingDir 'build/newdeploy/try/bin'
       executable 'sh'
       args arguments, url
       ext.output = { return standardOutput.toString() }                        
    }
}

我试过跟随并且成功了。而不是添加一个单独的任务来复制，而是在任务A本身中添加了复制功能

task A {
    description = 'Rolls out new changes'
    doLast {
        def url = "https://${serverName}/xxx/try.zip"
        def copiedZip = 'build/newdeploy/try.zip'
        logger.lifecycle("Downloading $url...")
        file('build/newdeploy').mkdirs()
        ant.get(src: url, dest: copiedZip, verbose: true)
        def outputDir = file("build/newdeploy")
        copy {
          from zipTree(zipFile)
          into outputDir
        }
    }
}

task C (type: Exec, dependsOn: 'A') {
    doLast {
       workingDir 'build/newdeploy/try/bin'
       executable 'sh'
       args arguments, url
       ext.output = { return standardOutput.toString() }                        
    }
}

跳过任务，因为它没有源文件，也没有以前的输出文件

Skipping task as it has no source files and no previous output files
