Gradle distributionUrl与“Ionic cordova run Android”更改到旧版本，构建失败

Question

我已经将gradle-4.1-all.zip中的Gradle distributionUrl更新为https://services.Gradle.org/distributions/gradle-6.1.1-all.zip，但是当我运行Ionic cordova run Android时，它会恢复到4.1-all.zip文件。这发生在终端到达的时候：

ANDROID_HOME=C:\Users\me\AppData\Local\Android\SDK
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_181
studio
Subproject Path: CordovaLib

Subproject Path: app

然后导致

FAILURE: Build failed with an exception.

*Where:
Build file 'C:\Users\me\Desktop\....\platforms\android\CordovaLib\build.gradle' line 40

* What went wrong:
A problem occurred evaluating project':CordovaLib'.
> Failed to apply plugin [id 'com.android.internal.version-check']
 > Minimum supported Gradle version is 6.1.1. Current version is 4.1...

本例中的第40行是apply plugin:'com.android.library'

classpath 'com.andorid.tools.build:gradle:4.0.1'
classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'

Answer 1

事实证明，Gradle版本位于几个位置。

为了解决这个问题，我在以下位置找到了distributionUrl作为变量:Platforms\Android\Cordova\lib\builders\studioBuilder.js和Platforms\Android\Cordova\lib\builders\gradleBuilder.js

这两个文件都包括

var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-4.1-all.zip';
