最近遇到了通过 Jenkins agent 无法上传 artifacts 到 Artifactory 的情况，具体错误如下：

这个问题产生的原因是通过 HTTPS 来上传文件的时候没有通过 Java 的安全认证。解决这个问题的办法就是重新生成认证文件，然后导入即可，具体的步骤如下。
生成安全认证（Security Certificate）文件#
步骤如下：
- 首先生成通过浏览器打开的你的 Artifactory 网址
- 在网址的左侧应该有一个锁的图标，点击 Connection is secure -》Certificate is valid -》Details -》 Export
- 选择 DER-encoded binary, single certificate (*.der) 生成认证文件
比如我生成的安全认证文件的名字叫：artifactory.mycompany.der（名字可以任意起，只要后缀名不变即可）
通过命令行导入安全认证#
登录到那台有问题的 Solaris agent，上传 artifactory.mycompany.der 到指定目录下，然后找到 cacerts 的路径，执行如下命令：
root@mysolaris:/# keytool -import -alias example -keystore /usr/java/jre/lib/security/cacerts -file /tmp/artifactory.mycompany.der
# 然后选择 yes
这时候会提示你输入密码，默认密码为 changeit，输入即可。然后重启你的 JVM 或是 VM。等再次通过该 Agent 上传 artifacts，一切恢复正常。
