如何在build.gradle中声明gradle版本5.0？ [英] How to declare gradle version 5.0 in build.gradle?

问题描述

当Gradle为4.x时，我使用了任务包装器，但是当我将 gradleVersion 更改为5.0时，gradle包装器状态无法添加相同名称的任务。当我将其从4.8更改为4.9时，即使是4.x，也没有发生这种情况。 Gradle是否改变了任务包装器的工作方式？

I used task wrapper when Gradle was 4.x but when I change gradleVersion to 5.0 , gradle wrapper states that it can't add a task with the same name. This didn't happen when it was 4.x when I could just change from 4.8 to 4.9 without issues. Does Gradle changed how task wrapper works?

推荐答案

定义自定义<自Gradle 4.8版本起，构建脚本中的code> wrapper 任务已被弃用，请参见第4.8级折旧（覆盖Gradle的内置任务部分）

Defining a custom wrapper task in your build script has been deprecated since Gradle 4.8 version, see Gradle 4.8 depreciations (section Overwriting Gradle's built-in tasks" section)

在4.8（及5.0之前）中，如果仍然定义自定义包装器任务，则应该显示以下警告消息：

Since version 4.8 (and before 5.0) you should have a warning message as below if you still define a custom wrapper task:

$ ./gradlew clean --warning-mode all

$ ./gradlew clean --warning-mode all

>配置项目：

创建名为包装器的自定义任务已被弃用，并计划在Gradle 5.0中删除。

Creating a custom task named 'wrapper' has been deprecated and is scheduled to be removed in Gradle 5.0.

您可以使用$ b $配置现有任务。 b'wrapper {}'语法或使用其他
名称创建您的自定义任务。'。

You can configure the existing task using the 'wrapper { }' syntax or create your custom task under a different name.'.

ce，自定义 wrapper 任务的支持已在Gradle 5.0中删除，因此您需要使用新的方式来配置包装器：

As announced, the support for custom wrapper task has been removed in Gradle 5.0, so you need to use the new way for configuring the Wrapper:

// Configuring the wrapper, the old way (gradle < 4.8 )
// see https://docs.gradle.org/4.4/userguide/gradle_wrapper.html#sec:wrapper_generation
task wrapper(type: Wrapper) {
    gradleVersion = '4.4'
    distributionType = Wrapper.DistributionType.BIN
}

// Configuring the wrapper, the new way (since Gradle 4.8) 
// see https://docs.gradle.org/current/userguide/gradle_wrapper.html#customizing_wrapper
wrapper{
    gradleVersion = '5.1'
    distributionType = Wrapper.DistributionType.BIN
}
