我有一个使用 1.1 版 tomcat maven 插件的完整项目。我试图切换到最后一个 maven tomcat 插件版本，在pom.xml：
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<configuration>
<contextFile>src/main/webapp/META-INF/context.xml</contextFile>
</configuration>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.9</version>
</dependency>
</dependencies>
</plugin>
但是，使用tomcat7:run而不是tomcat:run我启动项目会收到以下错误：
