在Tomcat7插件URL中应该加上/text/
如下所示：

部署命令：tomcat7:deploy for rdeploying：tomcat7:redeploy

配置Tomcat7插件 在 pom.xml

<plugin>
<!-- tomcat deploy plugin -->
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<url>http://localhost:8080/manager/text</url>
<server>TomcatServer</server>
<username>XXXX</username>
<password>XXXX</password>
<path>/XXXX</path>
</configuration>
</plugin>


tomcat-user.xml 配置

<role rolename="tomcat" />
<role rolename="manager-gui" />
<role rolename="manager-script" />
<user username="tomcat" password="tomcatuser"
roles="tomcat,manager-gui,manager-script" />


注意：我也测试了与Tomcat 8相同的设置。所以这个设置可以适用于这两个版本。

已知的限制
tomcat7 mojo还没有一些目标。这些容器目标可以与tomcat6 mojo一起使用，您只需要更新您的pom中的管理器URL。

使用http: //localhost:8080/manager/text而不是默认的tomcat6 url。
