Question

仅仅一周后我就可以在同一台Mac机器上运行相同的项目，但升级后我的系统android studio升级到3.0稳定发布时，这个Cordova项目已停止从控制台构建并通过android studio。

请在下面查看控制台运行命令例外日志

Android Studio错误日志：

找不到com.android.tools.build:gradle:2.3.3。在以下位置进行了搜索：https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.3.3/gradle-2.3.3.pom https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.3.3/gradle-2.3.3.jar要求：项目：CordovaLib添加Google Maven存储库和同步项目打开文件

Answer 1

自己找到解决方案，将下面给出的buildscript和依赖项复制/粘贴到android studio Cordova库＆＃39; build.gradle＆＃39;而且在项目层面＆＃39; build.gradle＆＃39; ：

buildscript {
    repositories {
        mavenCentral()
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }

}

现在我能够再次构建项目。

Answer 2

更新：结果证明这是一个已知的Cordova / Android Studio 3.0问题here。基本上Android Studio 3删除了对Cordova正在使用的旧的按会议项目目录结构的支持。所以只有较旧的android gradle插件和gradle版本对才能工作（如下所示），直到Cordova解决了这个问题。

MacOS X version -> 10.12.6
node --version -> 8.0.0
npm --version -> 5.5.1
cordova --version -> 7.1.0
Android Studio IDE -> 3.0

解决问题的步骤：

myApp > cordova run android

ANDROID_HOME=/Users/Luckyjohn/Library/Android/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home
Subproject Path: CordovaLib
Error: spawn EACCES

1）将Cordova“myApp / platforms / android”项目的Android gradle插件和gradle版本对更改为Cordova gradle构建配置和Android Studio 3.0 IDE支持的一对。旧值在下面注释掉了。

.../android build.gradle:
dependencies {
    classpath 'com.android.tools.build:gradle:2.3.0'
    //classpath 'com.android.tools.build:gradle:2.2.3'
}
.../android/CordovaLib build.gradle:
dependencies {
    classpath 'com.android.tools.build:gradle:2.3.0'
    //classpath 'com.android.tools.build:gradle:2.2.3'
.../gradle/wrapper/gradle-wrapper.properties:
distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
#distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

2）Cordova平台上的chmod执行位“android”目录和所有子目录：

cd to .../myApp/platforms
chmod -R 755 android

不确定这是必需的，先做＃1然后测试。

3）我为我的Android sdk目录及其所有子目录做了同样的事情。不确定这是必需的，先做＃1并测试。
