gradle - 如何在包装器任务中设置分发类型

Question

这看起来应该很简单，但我就是无法让它工作。我正在尝试设置包装器任务的 distributionType 属性，但它不起作用:

task wrapper(type: Wrapper) {
    gradleVersion = '4.1'
    distributionType = DistributionType.ALL
}

当我尝试运行包装器任务时，出现以下错误:

$ gradle wrapper

FAILURE: Build failed with an exception.

* Where:
Build file '.../build.gradle' line: 6

* What went wrong:
A problem occurred evaluating root project 'project'.
> Could not get unknown property 'DistributionType' for task ':wrapper' of type org.gradle.api.tasks.wrapper.Wrapper.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 0.613 secs

请注意，我已经下载了最新的 Gradle 版本 (4.1) 并将其添加到我的 bash 路径中:

$ gradle -version

Groovy:       2.4.11
Ant:          Apache Ant(TM) version 1.9.6 compiled on June 29 2015
JVM:          1.8.0_144 (Oracle Corporation 25.144-b01)
OS:           Mac OS X 10.12.6 x86_64

我尝试设置它的方式似乎是合理的，因为它与我设置 gradleVersion 的方式相同，并且考虑到 Wrapper.java 的实现:

public class Wrapper extends DefaultTask {

    public enum DistributionType {
        /**
         * binary-only Gradle distribution without sources and documentation
         */
        BIN,
        /**
         * complete Gradle distribution with binaries, sources and documentation
         */
        ALL
    }

    //...

    public void setGradleVersion(String gradleVersion) {
        this.gradleVersion = GradleVersion.version(gradleVersion);
    }

    // ...

    public void setDistributionType(DistributionType distributionType) {
        this.distributionType = distributionType;
    }

    // ...

}

我已经看到了这个解决方法(如 this StackOverflow 答案中所述)，它有效，但感觉有点太老套了......

task wrapper(type: Wrapper) {
    gradleVersion = '2.13'
    distributionUrl = distributionUrl.replace("bin", "all")
}

我做错了什么？

我还使用 --stacktrace --debug 重新运行。我不会发布整个输出(相当大)，而是发布看起来最相关的部分:

> Could not get unknown property 'DistributionType' for task ':wrapper' of type org.gradle.api.tasks.wrapper.Wrapper.

最终，这表明我们失败了 here .

我的猜测是:

ConfigureUtil helper 将解析策略设置为 Closure.OWNER_ONLY。在 build.gradle 中，您无权访问 DistributionType 枚举。如果您在执行任务之前导入此枚举:

import org.gradle.api.tasks.wrapper.Wrapper.DistributionType

一切都会好起来的。另一种解决方案是分配

distributionType = Wrapper.DistributionType.ALL
