How to use maven plugin tomcat7:run with multiple contexts (WARs)?
提问by mckamey
I've been using mvn tomcat7-maven-plugin:run -am -pl :foosuccessfully to run just a single project at a time in Tomcat like is shown here. Now I'd like to have multiple modules run under the same port but different contexts. For instance, I'd like to have:
我一直在mvn tomcat7-maven-plugin:run -am -pl :foo成功地使用，一次只在Tomcat 中运行一个项目，如下所示。现在我想让多个模块在同一个端口但不同的上下文下运行。例如，我想要：
/ => foo.war
/bar => bar.war
Here's an example pom.xml snippet that I've been working with:
这是我一直在使用的示例 pom.xml 片段：
<project><!-- ... -->
<build><!-- ... -->
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.0-SNAPSHOT</version>
<configuration>
<path>/</path>
<port>8080</port>
<addContextWarDependencies>true</addContextWarDependencies>
<addWarDependenciesInClassloader>true</addWarDependenciesInClassloader>
<warSourceDirectory>${project.build.directory}/${project.build.finalName}/</warSourceDirectory>
</configuration>
<dependencies>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>bar</artifactId>
<version>${project.version}</version>
<type>war</type>
<scope>tomcat</scope>
</dependency>
</dependencies>
</plugin>
</plugins>
</pluginManagement>
</build>
<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>
</project>
Is this possible with the tomcat7-maven-plugin:runplugin? I'm struggling to find the correct syntax to get it to play well. When I run the mavencommand to run it, it only runs the first one it finds in the project hierarchy. And if I run them with the <fork>true</fork>or obviously from different terminals then I get "java.net.BindException: Address already in use :8080".
这可以通过tomcat7-maven-plugin:run插件实现吗？我正在努力寻找正确的语法来让它发挥良好的作用。当我运行maven命令来运行它时，它只运行它在项目层次结构中找到的第一个。如果我使用<fork>true</fork>或显然来自不同的终端运行它们，那么我会得到“java.net.BindException：地址已经在使用：8080”。

As it was already suggested, use <webapps>section of plugin configuration, but add additional parameter <asWebapp>true</asWebapp>for every webapp, i.e:
正如已经建议的那样，使用<webapps>插件配置部分，但<asWebapp>true</asWebapp>为每个 webapp添加额外的参数，即：
<webapps>
<webapp>
<groupId>com.company</groupId>
<artifactId>mywebapp</artifactId>
<version>1.0</version>
<type>war</type>
<asWebapp>true</asWebapp>
</webapp>
<webapp>
<groupId>com.company</groupId>
<artifactId>mywebapp2</artifactId>
<version>2.0</version>
<type>war</type>
<asWebapp>true</asWebapp>
</webapp>
</webapps>
These additional webapps are deployed with ${artifactId}context path by default.
${artifactId}默认情况下，这些额外的 web 应用程序使用上下文路径进行部署。
It looks like without this parameter additional webapps get silently discarded when you run something like mvn tomcat7:run(tried on stable version 2.0). Related Jira issuetells it was done for "backward compatibility".
看起来如果没有这个参数，当您运行类似mvn tomcat7:run（在稳定版本 2.0 上尝试）时，额外的 webapps 会被悄悄丢弃。相关的 Jira 问题表明它是为了“向后兼容性”而完成的。

Use something like
使用类似的东西
<configuration>
<webapps>
<webapp>
<groupId>com.company</groupId>
<artifactId>mywebapp</artifactId>
<version>1.0</version>
<type>war</type>
</webapp>
</webapps>
</configuration>
