jenkins 启动slave，出现com.sun.deploy.net.FailedDownloadException: Unable to load resource: http://127.0.0.1:8080/jnlpJars/remoting.jar
master: linux
slave: win7 64位系统
在配置好系统后，采用jnlp的方式启动slave节点，报错如下：
com.sun.deploy.net.FailedDownloadException: Unable to load resource: http://127.0.0.1:8080/jnlpJars/remoting.jar

修改办法：
到jenkins面板： http://127.0.0.1:8080， 进入Manage Jenkins ，选择Configure System， 修改Jenkins Location选项下面的Jenkins URL为master机器的http://IP:port, 然后重新生成jnlp文件发送到slvae节点，然后右键选择Launch。
如果，不想修改Jenkins的 URL，那么用notepad++打开slave-agent.jnlp文件，将其中的127.0.0.1修改为master机器的IP或者域名，也可以。
