Cordova项目错误：生成EACCES

Question

就在一周前，我能够在同一台Mac机器上运行相同的项目，但是将我的系统android studio升级到3.0稳定版后，此Cordova项目已停止从控制台和通过android studio进行构建。

请检查以下是控制台运行命令异常日志

Android Studio错误日志：

找不到com.android.tools.build:gradle:2.3.3。 在以下位置搜索： 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必需：project：CordovaLib添加Google Maven存储库并同步项目Open File

Answer 1

自己找到解决方案，将以下给定的buildscript和依赖项复制/粘贴到android studio Cordova库'build.gradle'中，也粘贴到项目级别'build.gradle'中：

buildscript {
    repositories {
        mavenCentral()
        google()
    }

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

}

现在我可以再次构建该项目。

Answer 2

更新：事实证明这是此处的已知Cordova / Android Studio 3.0问题。 基本上，Android Studio 3删除了对Cordova使用的旧的按惯例构建项目目录结构的支持。 因此，只有更旧的android gradle插件和gradle版本对才起作用（如下所示），直到Cordova修复了该问题。

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支持的对。 旧值在下面注释掉。

.../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“ android”目录和所有子目录上的chmod执行位：

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

不确定是否需要这样做，请先执行＃1并进行测试。

3）我对Android sdk目录及其所有子目录也做了相同的操作。 不确定是否需要这样做，请先执行＃1并进行测试。
