Jenkins部署项目到Tomcat8，项目名为ROOT出现问题?报错

最近引入了Jenkins自动化部署，前面拉代码、打包都没问题，唯独部署出问题。

为了访问方便（能从根目录访问网站），我们是将项目打包为ROOT.war丢到tomcat的webapps下的。

已经配置好了tomcat的相关用户deploy并给予了权限。

这里是我们的测试服务器以远程部署的方式给自己部署，也就是输入了自己的网址和端口号。

经测试，如果项目名字不是ROOT.war（比如起名abc.war），经过Jenkins构建并通过Deploy to container Plugin插件部署后，再次构建是可以覆盖前面的abc.war

但ROOT.war不能被覆盖，如果webapps下面有ROOT.war，直接构建部署会报错Error writing request body to server：

Build step 'Deploy war/ear to a container' marked build as failure
Finished: FAILURE

目前解决方案是：写一个本地脚本，在部署前将原有的ROOT.war和解压后的ROOT文件夹删掉，这样才能顺利部署。

因为后期打算用测试服务器以远程部署到线上服务器，可这样就没办法通过执行本地脚本清空原有项目，这个疑问还是要解决的。

恳求有Jenkins+Tomcat（+Git+Maven）部署经验的大牛指点
