构建Cordova Android项目时出错
嗨我正在尝试使用以下环境在Windows 7中使用android插件构建一个cordova项目
ANDROID_HOME=D:\DevTools\Android\Android_SDK_NDK\android-sdk JAVA_HOME=C:\Program Files\Java\jdk1.7.0_45 我生成了一个cordova项目
>cordova create CordovaProject io.xyz.hellocordova CordovaApp
并添加了android插件
>cordova platform add android
在做完之后我试着构建android项目
>cordova build android
这个尝试下载gradle-2.2.1-all.zip导致exception

可能是因为我的办公室防火墙/代理不允许下载zip文件。 但是我提取了zip文件并将路径变量设置为
GRADLE_HOME = C：\ gradle-2.2.1
即便如此，我也无法解决这个问题。 我明白了这个环境。 构建脚本中不接受路径变量，但我不确定在何处更改或绕过此步骤。
正如您所提到的，它看起来更像是一个网络问题。 如果您使用受限代理网络，则gradle下载将失败。 如果出现网络限制，您可以按照以下步骤解决此问题：
1) Download the required gradle version zip file from gradle distribution link and save it in local folder.
2) Navigate to PROJECT_ROOT_FOLDER/platforms/android/cordova/lib/builders folder and edit GradleBuilder.js file
3) Change the line from var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip'; to 'var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'file:///local/path/to/folder/where/gradle/zip/is/saved/gradle-2.2.1-all.zip'; and save the file
4) Try rebuilding android build.
您也可以尝试以下快速修复，
1) In command prompt execute the following command: export CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=file:///local/path/to/folder/where/gradle/zip/is/saved/gradle-2.2.1-all.zip
2) Execute the following command: cordova run android
您需要通过将这些行添加到~/.gradle/gradle.properties来设置gradle代理（如果文件不存在，则创建该文件）：
systemProp.http.proxyHost=myproxy.com systemProp.http.proxyPort=123 systemProp.https.proxyHost=myproxy.com systemProp.https.proxyPort=123
当然，替换你的代理和端口。
当我通过此错误执行命令cordova build android时，我遇到了同样的问题。 我被试了更多1小时终于我禁用了我的防病毒软件 （Avast）并再次执行命令，现在它已成功执行。
我使用浏览器从https://services.gradle.org/distributions下载了证书，并将其添加到我的Java安装cacert文件中，之后它对我有用..
例：
C：\ Program Files \ Java \ jdk1.8.0_40 \ jre \ lib \ security> keytool -import -alias gradle -keystore cacerts -trustcacerts -fi le D：\ Configurations \ certificates \ gradle.cer
