为ubuntu jvm/java 添加证书 。

Ⅰ. 能不能为ubuntu jvm/java 添加证书 。

2. 最近使用devsidecar时碰到一个问题，java script 连接github时，出现连接错误，有迹象表明是jvm证书问题。错误信息如下：

###WARN: Cannot read project manifest -- Cause: PKIX path building failed:
  sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
  Cannot find `nextflow-io/hello` -- Make sure exists a GitHub repository at this address `https://github.com/nextflow-io/hello`

到底是用 java 连接还是 java script 连接 github ？

java的话，看看这个。

谢谢，按照你的指导为java安装了证书，但依旧连接不了github，可能是所用的软件包有问题。

无论如何，谢谢了！
