Apache Tomcat Maven插件的日志配置仅执行警告目标？

Question

我想通过描述为@http://tomcat.apache.org/maven-plugin-2.1/tomcat7-maven-plugin/exec-war-only-mojo.html#extraResources的extraResources标记指定一个日志配置文件，并得到以下maven错误

Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:exec-war-only (tomcat-run) on project iot-service-embedded-tomcat: Unable to parse configuration of mojo org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:exec-war-only for parameter extraResource: Cannot configure instance of org.apache.tomcat.maven.plugin.tomcat7.run.ExtraResource from log4j.properties

下面是maven插件条目：

<plugin>
   <groupId>org.apache.tomcat.maven</groupId>
   <artifactId>tomcat7-maven-plugin</artifactId>
   <version>2.1</version>
   <executions>
      <execution>
         <id>tomcat-run</id>
         <goals>
            <goal>exec-war-only</goal>
         </goals>
         <phase>package</phase>
         <configuration>
            ...
            <extraResources>
               <extraResource>
                  log4j.properties
               </extraResource>
            </extraResources>
            <extraDependencies>
               ...
               <extraDependency>
                  <groupId>log4j</groupId>
                  <artifactId>log4j</artifactId>
                  <version>1.2.17</version>
                  <scope>compile</scope>
               </extraDependency>
            </extraDependencies>
            ...
         </configuration>
      </execution>
   </executions>
</plugin>

Answer 1

通过查看Maven模型资源类中的getter/setter，我找到了答案。正确的语法是：

<extraResources>
   <extraResource>
      <directory>path/to/resource/</directory>
      <includes>
         <include>resource.file.name</include>
      </includes>
   </extraResource>
</extraResources>
