如何设置依赖gradle任务的属性

我想设置一个“通用”任务，它将为多个平台构建应用程序包（它使用 javafxpackager）。该任务的机制适用于创建所有平台捆绑包，但区别在于任务使用的各种属性。

我原以为我会为每个平台创建单独的更高级别的任务，在其中设置平台特定的属性，然后调用/执行/（此处替换正确的 gradle 术语）通用任务。例如。，

task buildMacBundle(dependsOn: ['macBundleConfig', 'buildAppBundle']) << {
  // set Mac-specific properties (project.ext properties?)
  // call/invoke/execute or whatever the mechanism is called, buildAppBundle task
    buildAppBundle.mustRunAfter macBundleConfig
    println "building a Mac app bundle"
}

task macBundleConfig << {
    println "executing macBundleConfig"
    ext {
        nativeType = "dmg"
        bundleAppName = 'My App'
    }
    delete ("${buildDir.name}/dist/${bundleAppName}.dmg")
}


task buildWindowsBundle << {
  // omitted for brevity, but just like buildMacBundle except for property values
}

task buildAppBundle << {

    println "nativeType: ${project.ext.nativeType}" // it stumbles here!

    def cmd = [
        "${javapackager}",
        "-deploy",
        "-native", "${project.ext.nativeType}",
        "-name",
        "${project.bundleAppName}",
        "-outdir",
        "${buildDir.name}${File.separator}dist",
        "-outfile",
        "MyApp",
        "-srcdir",
        "${buildDir.name}${File.separator}${libsDir.name}",
        "-appclass",
        "org.pf.app.MyApp"
    ]

    println cmd.join(" ")

    def javapackager = exec {
        workingDir "${project.projectDir.absolutePath}"
        commandLine cmd
    }
}

但是当我运行“buildMacBundle”时，我得到

* What went wrong:
Execution failed for task ':buildAppBundle'.
> cannot get property 'nativeType' on extra properties extension as it does not exist

如何定义特定任务中的属性，然后调用通用任务？

我遇到了类似的问题，我发现如果你切换

ext {
    nativeType = "dmg"
    bundleAppName = 'My App'
}

with

project.ext {
    nativeType = "dmg"
    bundleAppName = 'My App'
}

它应该有效。 据我所知，这是一个范围问题 - 在第一种情况下，您设置了属性Task，在第二种情况下，对于Project.

顺便说一句，我认为buildAppBundle.mustRunAfter macBundleConfig对你来说太晚了，因为它是buildMacBundle任务，因此运行顺序为：

1. mac 捆绑配置
2. 构建AppBundle
3. 构建MacBundle

并且只有在 3 期间才会进行配置mustRunAfter of buildAppBundle将被改变。
