maven出错

Compilation error
org.eclipse.jdt.internal.compiler.classfmt.ClassFormatException

Tomcat默认版本和JDK不比配，可以指定JDK

<plugin>
          <groupId>org.apache.tomcat.maven</groupId>
          <artifactId>tomcat7-maven-plugin</artifactId>
          <version>2.2</version>
          <configuration>
            <port>8888</port>
          </configuration>

<port>8888</port>

为了检验是我们指定的tomcat起作用

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project travel: Compilation failure: Compilation failure: 在报错下面有说哪个类出错，目前知道有用处理办法将类删除，重写
