在jdk 1.7中使用javah maven-antrun-plugin，classes.jar变成了tools.jar

Question

在针对Mac的JDK1.7中，com.sun.tools.javah.main的位置从classes.jar移到了tools.jar。因此,Maven的maven-antrun-plugin找不到run the javah任务,并抛出ClassNotFound异常：

Caused by: java.lang.ClassNotFoundException: com.sun.tools.javah.Main
at org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy.loadClass(SelfFirstStrategy.java :50)

1.7位置：/library/java/javavirtualmachines/1.7.0.jdk/contents/home/lib/Tools.jar

这似乎是maven 3.0.4版的一个bug或失败。我曾考虑过让tools.jar成为一个插件依赖项，但这似乎不太对。我尝试了这些解决方案，但我无法让它们奏效：

JDK tools.jar作为maven依赖项

Maven：如何以独立于操作系统的方式加载tools.jar/classes.jar？

答案是添加tools.jar作为插件的依赖项。包含 ... 中的以下部分

 <build>   
 <plugins>
   <plugin>
     <artifactId>maven-antrun-plugin</artifactId>
     <version>1.7</version>
     <executions>
       <execution>
         <phase>compile</phase>
         <configuration>
           <target>
             <property name="runtime_classpath" refid="maven.runtime.classpath"/>
             <property name="test_classpath" refid="maven.test.classpath"/>
             <property name="plugin_classpath" refid="maven.plugin.classpath"/>

             <echo message="runtime classpath: ${runtime_classpath}"/>
             <echo message="test classpath:    ${test_classpath}"/>
             <echo message="plugin classpath:  ${plugin_classpath}"/>

           </target>
         </configuration>
         <goals>
           <goal>run</goal>
         </goals>
