maven配置Tomcat插件 报如下错

path 和 port 属于Tomcat的配置文件,与上面的groupId 和artifactId不同级,你把path和port放在configuration里面就可以了

org.codehaus.mojo
tomcat-maven-plugin
1.1

/wp
8080
UTF-8
http://localhost:8080/manager/html
tomcat6

你配置的有问题，应该还有一个configuration标签。全部的配置如下:

plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <!-- or if you want to use tomcat 6.x
    <artifactId>tomcat6-maven-plugin</artifactId>
    -->
    <version>2.2</version>
    <configuration>
      <!-- http port -->
      <port>9090</port>
      <!-- application path always starts with /-->
      <path>/</path>
      <!-- optional path to a context file -->
      <contextFile>${tomcatContextXml}</contextFile>
      <!-- optional system propoerties you want to add -->
      <systemProperties>
        <appserver.base>${project.build.directory}/appserver-base</appserver.base>
        <appserver.home>${project.build.directory}/appserver-home</appserver.home>
        <derby.system.home>${project.build.directory}/appserver-base/logs</derby.system.home>
        <java.io.tmpdir>${project.build.directory}</java.io.tmpdir>
      </systemProperties>
      <!-- if you want to use test dependencies rather than only runtime -->
      <useTestClasspath>false</useTestClasspath>
      <!-- optional if you want to add some extra directories into the classloader -->
      <additionalClasspathDirs>
        <additionalClasspathDir></additionalClasspathDir>
      </additionalClasspathDirs>
    </configuration>
    <!-- For any extra dependencies needed when running embedded Tomcat (not WAR dependencies) add them below -->
    <dependencies>
      <dependency>
        <groupId>org.apache.derby</groupId>
        <artifactId>derby</artifactId>
        <version>\${derbyVersion}</version>
      </dependency>
      <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4</version>
      </dependency>
    </dependencies>
  </plugin>
