tomcat7-maven-plugin：运行多个webapps但端口8080已经在使用中
我正在尝试使用tomcat7-maven-plugin来设置嵌入式tomcat容器，在pre-integration-test阶段运行webapps，运行集成测试，然后在post-integration-test阶段关闭tomcat。 该项目是一个多模块maven项目（包含app1 ， app2等）。 父pom.xml如下所示，
org.apache.tomcat.maven tomcat7-maven-plugin 2.1 path/to/context.xml path/to/tomcat-users.xml true tomcat-run run pre-integration-test tomcat-shutdown shutdown post-integration-test
然后我就运行mvn clean integration-test --projects=app1,app2 。 当第二个应用程序启动时 ，我得到java.net.BindException ，

那么tomcat7-maven-plugin是否有配置在嵌入式tomcat中运行多个webapps？
请参阅tomcat7：运行 mojo参数：您可以配置插件执行以使用其他端口，类似于此配置：
tomcat-run run pre-integration-test 9090
当然，为第二个项目使用另一个端口。
它应该得到支持。 您应该在配置中配置webapps元素，Tomcat将部署所有应用程序： http ： //tomcat.apache.org/maven-plugin-2.0/tomcat7-maven-plugin/run-mojo.html
看看如何使用maven插件tomcat7：运行多个上下文（WAR）？
