我在Eclipse里建立一個Maven Project, Project Facets是 Dynamic Web Module是3.1， Java是1.8。然後我嘗試run maven tomcat7:deploy的時候出現以下錯誤

pom加上service-api试试

<dependency>
		    <groupId>javax.servlet</groupId>
		    <artifactId>servlet-api</artifactId>
		    <version>2.5</version>
		</dependency>

对于采用 http://localhost:8080/manager/ 来部署war包的情况，应该配置用户名和口令，并跟<tomcat>/conf/tomcat-users.xml中保持一致。注意tomcat-users.xml中的角色应当包括manager：

<user username='admin' password='...' roles='tomcat,manager'/>

在maven的pom.xml类似于：

<build><plugins>
<plugin>
  <groupId>...</groupId>
  <artificialId>...</artificialId>
  <version>...</version>
  <!-- 请查阅相应手册 确认phase和goal -->
  <phase>deploy</phase>
  <goals><goal>deploy</goal></goals>
  <configuration>
    <!-- 具体是不是这个请查阅maven-plugin手册 -->
    <tomcat-user>...</tomcat-user>
  </configuration>
</plugin>
</plugins></build>
