android - 用cordova构建android

Question

我有一个 ionic 移动应用程序，我一直在为 IOS 和 android 构建它。
但我不得不从我的电脑中删除 android studio，然后我重新安装它。
而现在，我无法构建 android!我收到了这个错误:

What went wrong: A problem occurred evaluating root project 'android'.

Failed to apply plugin [id 'com.android.application'] Minimum supported Gradle version is 4.1. Current version is 3.3. If using the gradle wrapper, try editing the distributionUrl in /Users/lamatatwany/Downloads/wesalApp/gradle/wrapper/gradle-wrapper.properties to gradle-4.1-all.zip

我试图将 gradle 版本更改为最新版本并得到另一个错误...

有人可以帮我解决这个问题。

Cordova 要求输出:

Requirements check results for android: Java JDK: installed 1.8.0 Android SDK: installed true Android target: installed android-27,android-26,android-24,android-23 Gradle: installed /Applications/Android Studio.app/Contents/gradle/gradle-4.4/bin/gradle

Requirements check results for ios: Apple OS X: installed darwin Xcode: installed 9.2 ios-deploy: not installed ios-deploy was not found. Please download, build and install version 1.9.0 or greater from https://github.com/phonegap/ios-deploy into your path, or do 'npm install -g ios-deploy' CocoaPods: installed (node:39026) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Some of requirements check failed (node:39026) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

当我在 GradleBuilder.js 中更新这一行时:

var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'https\://services.gradle.org/distributions/gradle-3.3-all.zip';

到 gradle-4.4-all.zip，出现以下错误:

BUILD FAILED in 1m 13s (node:39180) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: /Users/lamatatwany/downloads/wesalapp/platforms/android/gradlew: Command failed with exit code 1 Error output: FAILURE: Build failed with an exception.

• What went wrong: Could not determine the dependencies of task ':compileDebugJavaWithJavac'.

  Could not resolve all task dependencies for configuration ':debugCompileClasspath'. Could not resolve project :CordovaLib. Required by: project : Project : declares a dependency from configuration 'debugCompile' to configuration 'debug' which is not declared in the descriptor for project :CordovaLib.

你的cordova-android版本很旧。当前版本是 7.0.0 .
这经历了许多变化来处理 android 项目结构和 gradle 的变化。

尝试:

ionic cordova platform update android

否则删除平台，然后添加:

ionic cordova platform add android@latest

或者

ionic cordova platform add android@7.0.0
