maven常用插件之tomcat
插件作用：在maven项目中，使用tomcat6、tomcat7运行maven项目。
1.声明repository及pluginRepository
< repositories >
< repository >
< id >people.apache.snapshots</ id >
< url >http://repository.apache.org/content/groups/snapshots-group/</ url >
< releases >
< enabled >false</ enabled >
</ releases >
< snapshots >
< enabled >true</ enabled >
</ snapshots >
</ repository >
</ repositories >
< pluginRepositories >
< pluginRepository >
< id >apache.snapshots</ id >
< name >Apache Snapshots</ name >
< url >http://repository.apache.org/content/groups/snapshots-group/</ url >
< releases >
< enabled >false</ enabled >
</ releases >
< snapshots >
< enabled >true</ enabled >
</ snapshots >
</ pluginRepository >
</ pluginRepositories >
2.添加tomcat6、tomcat7插件
< plugins >
...
< plugin >
< groupId >org.apache.tomcat.maven</ groupId >
< artifactId >tomcat6-maven-plugin</ artifactId >
< version >2.0-SNAPSHOT</ version >
< configuration >
<!--
默认访问路径为：http://localhost:8080/${project.name}
下面指定访问路径为： http://localhost:8080
-->
< path >/</ path >
</ configuration >
</ plugin >
< plugin >
< groupId >org.apache.tomcat.maven</ groupId >
< artifactId >tomcat7-maven-plugin</ artifactId >
< version >2.0-SNAPSHOT</ version >
< configuration >
< path >/</ path >
</ configuration >
</ plugin >
...
</plugins
3.在settings.xml文件里添加groupId
< pluginGroups >
....
< pluginGroup >org.apache.tomcat.maven</ pluginGroup >
....
</ pluginGroups >
最后执行下面命令，就可以在tomcat里运行maven项目了
mvn tomcat6:run
mvn tomcat7:run
