在Intellij中,当我在本地运行Google App Engine时,为什么要清理并构建战争以查看更改？

Question

我正在使用谷歌应用程序引擎来制造战争,我注意到每当我进行本地更改时,我在本地运行时都不会应用它们.我已经发现,看到我所做的更改的唯一方法是运行a mvn clean,然后make,然后构建工件,然后部署.这是显示我的配置的屏幕截图:

如果我错过了上述任何步骤,重新启动服务器不会显示我所做的任何更改.我之前使用intellij制作了许多非谷歌应用引擎的webapps,我通常不必这样做.我该如何避免所有这些步骤？它们大大增加了重启服务器所需的时间.

如果它有帮助,这是我的pom.xml文件:
