Failed to create a temp file - Jenkins 无法创建任务

近日，突然发现任务集群的jenkins异常退出了，没有任何的迹象。后来排查到jenkins的job的日志后，找到了以下错误日志。

经过一番查找后，才发现是jenkins的一个bug引起，且可以通过增加Java Opts的一个文件编码的命令行参数解决：

-Dfile.encoding=UTF8

如

nohup java $SERVICE_OPTS -Dfile.encoding=UTF8  -jar $HOME/work/jenkins2/jenkins.war --httpPort=8080 > jenkins.log 2>&1 &
