android - 无法将任务 'wrapper' 添加为具有该名称的任务已存在

Question

安装 'react-native init AwesomeProject' 运行 react-native run-android 时出现此错误:

Could not determine java version from '11.0.1'.

快速谷歌建议我需要更新 Gradle-wrapper 中的 distributionUrl。完成此操作后，我面临一个新错误:

Cannot add task 'wrapper' as a task with that name already exists.

这表明问题出在文件中:

/AwesomeProject/android/build.gradle' line: 36

看起来像这样

task wrapper(type: Wrapper) {
    gradleVersion = '4.4'
    distributionUrl = distributionUrl.replace("bin", "all")
}

我一直在试图弄清楚这是做什么的。有些东西不能直接开箱即用，这似乎很奇怪。有人遇到类似问题吗？

Answer 1

你也可以更新

task wrapper(type: Wrapper) {
    gradleVersion = '4.4'    
    distributionUrl = distributionUrl.replace("bin", "all")
}

到

wrapper {
    gradleVersion = '4.4'
    distributionUrl = distributionUrl.replace("bin", "all")
}

作为

Overriding built-in tasks deprecated in 4.8 now produces an error.

Attempting to replace a built-in task will produce an error similar to the following:

Cannot add task 'wrapper' as a task with that name already exists.

参见任务和属性的最后一段: https://docs.gradle.org/5.2.1/userguide/upgrading_version_4.html
