在引用他人的tomcat项目初次运行时出现的错误
详细错误信息如下:

解决方法:
在 pom.xml 中，如果您包含了像 tomcat-catalina tomcat7-maven-plugin maven-compiler-plugin 这样的依赖项，请指定其依赖范围为provided。
<dependency><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.1</version><scope>provided</scope> <!----></dependency><dependency><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version><scope>provided</scope> <!----></dependency>
小知识：
1.test范围是指测试范围有效,在编译和打包时都不会使用这个依赖
2.compile范围是指编译范围内有效,在编译和打包时都会将依赖存储进去
3.provided依赖,在编译和测试过程中有效,最后生成的war包时不会加入
4.runtime在运行时候依赖,在编译时候不依赖
默认依赖范围是compile
