java - 构建 Cordova Android 项目时出错

Question

您好，我正在尝试在 Windows 7 中使用 android 插件构建一个 cordova 项目以下环境

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

现在在这样做之后我尝试构建 android 项目

>cordova build android

尝试下载 gradle-2.2.1-all.zip 会导致异常

可能是因为我办公室的防火墙/代理不允许下载 zip 文件。但我提取了 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。我知道环境。构建脚本不接受路径变量，但我不确定在哪里更改或绕过此步骤。

Answer 1

如您所述，它看起来更像是网络问题。如果您使用受限代理网络，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) 从 gradle 分发链接下载所需的 gradle 版本 zip 文件并将其保存在本地文件夹中。

2) 导航到 PROJECT_ROOT_FOLDER/platforms/android/cordova/lib/builders 文件夹并编辑 GradleBuilder.js 文件

3) 从 var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 更改行'http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip';
到
'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';并保存文件

4) 尝试重建 android 构建。

您也可以尝试以下方法作为快速修复，

1) 在命令提示符下执行以下命令:export CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=file:///local/path/to/folder/where/gradle/zip/is/saved/gradle-2.2.1-all。 zip

2) 执行以下命令:cordova run android
