build-helper-maven-plugin add-test-resource error

我有这个项目的结构：

/src
    /main
        /java
        /resources
    /test 
        /java
        /resources
    /it
        /java
        /resources

test用于单元测试和集成测试。我正在使用build-helper-maven-plugin将其他测试源/资源添加到类路径中，以便以后使用maven-surfire-plugin进行运行，maven-failafe-plugin用于。itunit testsintegration tests

插件配置如下：

         </goals>                                                
         <configuration>                                         
            <resources>                                          
               <directory>/src/it/resources</directory>
            </resources>                                         
         </configuration>                                        
      </execution>                                               
   </executions>                                                 
</plugin>       

这适用于（它们被正确地复制到 /target/test-classes），但不会复制 test 资源。我尝试过不同的组合：使用代替，使用特定的文件而不是目录...但两者都不起作用。test-sources<configuration><resource><directory>

堆栈跟踪，出现错误：

Caused by: org.apache.maven.plugin.PluginConfigurationException: Unable to parse configuration of mojo org.codehaus.mojo:build-helper-maven-plugin:1.9.1:add-test-resource for parameter directory: Cannot configure instance of org.apache.maven.model.Resource from src/it/resources

        at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209)

暂时，我已经修复了将集成测试资源添加到maven配置的问题：<build>

<build>
...
    <testResources>                               
       <testResource>                             
          <directory>src/it/resources</directory> 
       </testResource>                            
    </testResources>    
</build>

但是我宁愿将所有类路径修改集中在 .任何人都可以发布具有正确配置的示例吗？build-helper-maven-plugin

提前致谢。
