下载Gradle时发生java Ionic构建Android错误

Question

我对离子框架非常陌生：）

>npm install -g cordova
>npm install -g ionic
>ionic start test blank
>cd test
>ionic platform add 安卓

当我使用“>ionic build 安卓”时，开始下载gradle，但我无法下载并得到一个错误

是什么导致了这个错误？我如何修复它

我下载Gradle并将其安装在PC上，但它想再次下载。 我可以将Gradle添加到脱机项目中吗

Answer 1

我使用的是Ionic版本1.7.14和以下文件中的distributionUrlmyApp/platforms/android/cordova/lib/builders/GradleBuilder.js.

我必须指出这个答案中指定的本地下载的gradle

我也有同样的问题。我离线将gradle添加到我的项目中

从发布的链接（这里是http://services.gradle.org/distributions/gradle-2.2.1-all.zip）下载gradle后，将其粘贴到myApp\platforms\android\gradle\gradle-2.2.1-all.zip之类的地方，并在构建中进行粘贴。来自myApp\platforms\android\cordova\lib\build.js的js找到以下内容：

var distributionUrl = 'distributionUrl=http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip';

并将其替换为您自己的文件位置：

var distributionUrl = 'distributionUrl=../gradle-2.2.1-all.zip';

Answer 2

Cordova 6.0.0/Visual Studio代码0.10.6

TL；博士

手动下载http://services.gradle.org/distributions/gradle-2.2.1-all.zip

把它放在appName\platforms\android\gradle\

set CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=..\gradle-2.2.1-all.zip

启动代码并编译

说明：

格雷德堡。js将distributionUrl设置如下：

var distributionUrl=进程。env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL']| | http\://服务。格拉德尔。org/distributions/gradle-2.2.1-all。拉链

脚本在appName\platforms\android\gradle\wrapper中运行

输出为：

下载file://appname/platforms/android/gradle/gradle-2.2.1-all.zip

Answer 3

如果需要在网络上使用代理，请在%USER_HOME%/.gradle中添加一个gradle.properties文件，如下所示，但用代理详细信息替换这些值。这对我有用

gradlePropertiesProp=gradlePropertiesValue
sysProp=shouldBeOverWrittenBySysProp   
envProjectProp=shouldBeOverWrittenByEnvProp  
systemProp.system=systemValue    
systemProp.http.proxyHost=myproxy.com    
systemProp.http.proxyPort=8080    
systemProp.http.nonProxyHosts=\*.mydomain.com|localhost   
systemProp.https.proxyHost=myproxy.com    
systemProp.https.proxyPort=8080    
systemProp.https.nonProxyHosts=\*.mydomain.com|localhost

Answer 4

因为上面发布的解决方案需要包括。压缩到大约55MB的文件夹中

还可以使用以下命令强制CLI在生成过程中使用Ant而不是gradle：

cordova build android -- --ant

Answer 5

我遇到了这个问题，因为我们的网络代理阻止了zip文件的下载。以下是我的发现：

NOTE: this differs from the "accepted" answer in that we aren't modifying Cordova's library directly. This is far less prone to "error" or being overwritten when you run ionic state restore

1. 下载gradle-http://services.gradle.org/distributions/gradle-2.2.1-all.zip

2. 将此文件放入platforms/android/gradle。但是，如果要将其集成到构建过程中，您可能希望将其粘贴到不太易受影响的位置，并添加一个步骤将文件复制到该位置

3. 将环境变量CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL设置为../gradle-2.2.1-all.zip

   • linux/osx：将export CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL="../gradle-2.2.1-all.zip"添加到~/。bashrc文件
   • windows:setx CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL ../gradle-2.2.1-all.zip

4. 运行ionic build android

Answer 6

命令行中的另一个选项是在cordova build命令之前运行$ export JAVA_OPTS="-Dhttp.proxyHost=proxy-url.com -Dhttp.proxyPort=911 -Dhttps.proxyHost=secure-proxy-url.com -Dhttps.proxyPort=911"
