Cordova項目錯誤：生成EACCES

Question

就在一周前，我能夠在同一台Mac機器上運行相同的項目，但是將我的系統android studio升級到3.0穩定版后，此Cordova項目已停止從控制台和通過android studio進行構建。

請檢查以下是控制台運行命令異常日志

Android Studio錯誤日志：

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存儲庫並同步項目Open File

Answer 1

自己找到解決方案，將以下給定的buildscript和依賴項復制/粘貼到android studio Cordova庫'build.gradle'中，也粘貼到項目級別'build.gradle'中：

buildscript {
    repositories {
        mavenCentral()
        google()
    }

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

}

現在我可以再次構建該項目。

Answer 2

更新：事實證明這是此處的已知Cordova / Android Studio 3.0問題。 基本上，Android Studio 3刪除了對Cordova使用的舊的按慣例構建項目目錄結構的支持。 因此，只有更舊的android gradle插件和gradle版本對才起作用（如下所示），直到Cordova修復了該問題。

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

解決問題的步驟：

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）將Cordova“ myApp / platforms / android”項目的Android gradle插件和gradle版本對更改為Cordova gradle構建配置和Android Studio 3.0 IDE支持的對。 舊值在下面注釋掉。

.../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”目錄和所有子目錄上的chmod執行位：

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

不確定是否需要這樣做，請先執行＃1並進行測試。

3）我對Android sdk目錄及其所有子目錄也做了相同的操作。 不確定是否需要這樣做，請先執行＃1並進行測試。
