android - Ubuntu 16/Cordova 6.4/Android : Could not resolve com. android.tools.build:gradle

Question

我正在尝试在 Ubuntu 16 操作系统中将 Cordova 6.4 与 Android Studio 结合使用。

我已经正确安装了Android Studio并下载了SDK。

并且 npm 和 cordova 也已安装。

我尝试创建一个项目:

cordova create myapp
cd myapp
cordova platform add android

这会产生以下错误:

Adding android project...

如果我在那之后运行cordova run android，它仍然告诉 block 无法解析com.android.tools.build:gradle:2.2.0.错误。

在 Windows 下似乎没有发生同样的事情。

我在网上搜索过，但没有运气。有人知道怎么做吗？

下面的文章讲述如何将特定站点的ssl证书导入到java环境中。

<小时/>

第 1 步:下载证书

下载此文件。

或者在 Mozilla Firefox 上也是如此:

转到https://repo1.maven.org

• 点击地址栏左侧的绿色挂锁。
• 点击“详细信息”。
• 点击“查看证书”。
• 点击“详细信息”。
• 点击“导出”。
• 将文件导出到“X.509 证书 (PEM) (*.crt; *.pem)”

第 2 步:将证书添加到默认 java keystore

sudo keytool -import -alias MavenRepo -keystore $JAVA_HOME/jre/lib/security/cacerts -file /PATH/TO/YOUR/EXPORTED/FILE.crt

您的 $JAVA_HOME 变量通常在您的 .bashrc 文件中声明，因此您可以使用此命令，只需替换 /PATH/TO/YOUR/EXPORTED/FILE 参数。

PS : The default password of java keystore is : changeit

它使程序向前推进了一点，但仍然没有解决。

最后我通过重装操作系统解决了这个问题。

似乎与ubuntu或linux本身无关，重装操作系统后，codova和android studio在ubuntu中运行良好。
