前言：在jenkins添加ubuntu节点，发现启动代理报错
以下是报错：
[SSH] Checking java version of /usr/java/latest/bin/java
Couldn't figure out the Java version of /usr/java/latest/bin/java
bash: /usr/java/latest/bin/java: No such file or directory
。。。。。。
Could not find any known supported java version
Unable to install JDK unless a valid Oracle account username/password is provided in the system configuration.
以下是解决方法：
1.在添加节点界面，选择高级
2.在java路径下面，添加节点的jdk位置，并保存
效果：点击启动代理，成功连接
