Question

运行项目时总是在Resolving dependencies...报错，百度之后按教程将google()jcenter() 替换为阿里的之后也无济于事，错误信息为

添加证书之后还是不行，请问这是我Java版本的问题吗？我安装的是jdk1.8.0_31.
谢谢！

Answer 1

同问，遇到相同的问题，公司可以，在自己家连的wifi笔记本上就老是报这个错，导入证书也还是一样

Answer 2

添加阿里源之前，要看看你设置过代理没有。如果设置过代理，换成阿里源也是没用的

看问题2

Answer 3

怎么处理的？同样遇到了

Answer 4

Answer 5

问一下解决了吗？这边也遇到了，就挺坑的，iOS没有问题，只有android有问题。很烦
