构建Cordova Android项目时出错

Question

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

现在我这样做后,我试图建立Android项目

>cordova build android

这试图下载gradle-2.2.1-all.zip,这导致例外

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.构建脚本中不接受路径变量,但我不确定在哪里更改或绕过此步骤.

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
