java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.classes.views.index

  本来好好地项目，今天删除了一下pom.xml 重新更新了一下就出现了 ：

java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.classes.views.index_jsp

修改前 pom.xml

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>

修改后pom.xml

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <!--<scope>provided</scope>-->
</dependency>
<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.1</version> <!--<scope>provided</scope>-->
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
