<!--provided 被依赖包理论上可以参与编译、测试、运行等阶段，相当于compile，但是在打包阶段做了exclude的动作。适用场景：例如， 如果我们在开发一个web 应用，在编译时我们需要依赖 servlet-api.jar，但是在运行时我们不需要该 jar包，因为这个jar包已由应用服务器提供，此时我们需要使用 provided 进行范围修饰。-->

<!-- 添加Tomcat依赖 -->

<!-- 添加JSTL依赖 -->

<artifactId>jstl</artifactId>
<!-- 如果没有指定 scope值，该元素的默认值为 compile。被依赖包需要参与到当前项目的编译，测试，打包，运行等阶段。打包的时候通常会包含被依赖包。-->
