Google App Engine本地服务器不起作用

Question

这样我就可以使用ant来构建我的应用程序，但是当我去运行服务器时会显示此消息

 [echo] GAE started locally. You can go to http://localhost:8080/_ah/admin

 BUILD SUCCESSFUL

当我转到http://localhost:8080/_ah/admin它抛出404页面未找到错误。 我在这里做错了什么？ 似乎服务器一启动就关闭，没有给我时间在浏览器中进行测试。

我试过在/buildtools/appengine-java-sdk-1.8.8/bin/dev_appserver.sh中添加“ sleep 5”命令，但似乎没有延迟服务器关闭的时间。

由于有人问到这里是蚂蚁脚本

#!/bin/sh

# This file is designed to be includable in other scripts to encapsulate
# the code that finds build tools. Both release.sh and ant.sh need to
# use the same buildtools.
