与Gradle相关的任务不会将命令行选项传递给父任务 [英] Gradle dependent task doesn't pass command line options to parent task

问题描述

我正在编写一个自定义Gradle任务，该任务接受命令行中的选项。该部分按预期工作。导致我出现问题的是，调用依赖任务时，命令行选项被拒绝，因为它与依赖任务无关。以下是一个演示问题的示例：

I'm writing a custom Gradle task that accepts an option from the command line. That part works as expected. What's causing me issues is that calling a dependent task, the command line option is rejected because it's not relevant to the dependent task. Here's a sample that demonstrates the issue:

class CustomTask extends DefaultTask {
    @Option(option = "stuff", description = "Custom task stuff")
    String stuff

    @TaskAction
    void action() {
        if (this.stuff?.trim()) {
            println this.stuff
        }
        else {
            throw new InvalidUserDataException("No stuff!")
        }
    }
}

task custom(type: CustomTask)

task depends(dependsOn: 'custom')

以下是路径：

1. 渐​​变自定义正确引发异常


2. gradle自定义--stuff = mystuff 发出 mystuff 当任务运行时。


3. 等级取决于正确引发相同的异常


4. 等级取决于--stuff = mystuff 失败，并显示未知命令行选项'--stuff'

1. gradle custom correctly throws an exception
2. gradle custom --stuff=mystuff emits mystuff when the task runs.
3. gradle depends correctly throws the same exception
4. gradle depends --stuff=mystuff fails with Unknown command-line option '--stuff'

如何使命令行选项-东西传递给自定义任务，何时调用 depends 任务？

How do I make the command line option --stuff pass through to the custom task when calling the depends task?

推荐答案

不幸的是，这是选项 https：// docs的已记录限制之一。 gradle.org/current/userguide/custom_tasks.html#limitations

您可以改用build属性，并使用传递它们-Pstuff =某物

You could use build properties instead, and pass them in with -Pstuff=something
