为什么任务包装函数不起作用

Question

关于如何修复gradle版本，有很多很好的建议，但有些已经过时了，或者我只是找不到建议的路径。对我来说，一个解决方案是Project>Project Structure>Project>Gradle Version。

在这里我可以把它改成支持的版本，并且成功地构建项目。

从这个链接，它暗示这是设置你的gradle包装的方式。

因此，我希望Project/Platforms/Android/Gradle/Wrapper/Gradle-Wrapper.properties中有DistributionURL=http\://services.gradle.org/Distributions/Gradle-2.14.1-all.zip，而这正是它的DistributionURL=http\:/services.gradle.org/Distributions/Gradle-2.13-all.zip。

无法直接更改此文件project/platforms/android/gradle/wrapper/gradle-wrapper.properties，因为在每次构建之后，它将恢复到gradle-2.13-all.zip。

这是怎么回事？找不到任何东西来解释它为什么不断更改distributionurl=http\:/services.gradle.org/distributions/gradle-2.13-all.zip。有人能解释一下吗？也许是我错过的很愚蠢的东西。谢谢你。

'gradlew包装器抛出错误，因为某些包装器在maven下不存在，子build.gradle使用它下载2.14.1.prom和2.14.1.jar。本链接将对其进行解释。

发现问题

为什么它不停地改回2.13-all.zip的问题是因为这一行，var distributionUrl=process.env['cordova_android_gradle_distribution_url']'http\\\:/services.gradle.org/distributions/gradle-2.13-all.zip'；中的[project name]/platforms/android/cordova/lib/builders/gradlebuilder.js而不是~/android/lib/gradlebuilder.js。（第164行）

Answer 1

这里有一个修复：：在Gradle文件中添加这个

task wrapper(type: Wrapper){
   gradleVersion = '2.14.1'
}
