在添加tomcat嵌入jasper依赖项后，我遇到以下错误。

我在每一个IDE中都尝试过，但我在任何地方都会遇到同样的错误。请帮我理解原因。Maven会自动更新依赖项，但当我运行应用程序时，会出现上述错误。

我添加下面的代码在pom.xml

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>

这可能是罐子损坏的迹象。尝试从maven缓存中删除工件，或者简单地删除整个缓存（C:/Users/Vishal/.m2/repository/），以便从头开始重新创建。

Spring Boot项目中报告的类似问题也通过这种方式得到了解决。
