在Maven2中使用Sigar的问题

Question

在Maven2中使用Sigar时出现错误。我知道它无法找到本地库（dll或.so），因为我知道我不能将本地库复制到我的WEB-INF/lib目录中......我的问题是“如何将lib文件的目录复制到在我的WAR文件中使用Maven的WEB-INF/lib？

我想复制FROM的目录是：$ {basedir}/lib/ 我想复制到的目录是：$ {webapp.output}/WEB -INF/lib目录（我想？）

以下是错误：

java.lang.UnsatisfiedLinkError: org.hyperic.sigar.Sigar.getLoadAverage() 

这里是我的POM文件：

你可以配置maven war插件来复制附加文件/文件夹，如图所示here。像下面的东西。

<configuration> 
     <webResources> 
     <resource> 
      <directory>lib</directory> 
      <!-- override the destination directory for this resource --> 
      <targetPath>WEB-INF/lib</targetPath> 
     </resource> 
     </webResources> 
    </configuration>
