我正在尝试将我的应用程序从 JDK 6 移植到 JDK 7，当我尝试在 Netbeans IDE 中构建项目时，它给出了这个异常。

在不更改与复杂性相关的库的情况下执行此操作的另一种方法是将 ative2ascii-maven-plugin 升级到更高版本（至少 1.0-beta-1）。除此之外，请确保以下配置正确到位。

  1. 所有包含的内容都应该用 .

  2. 同样，所有排除项都应包含在

例如： 

      
     .....
    <includes>
    <include>
      ApplicationResources_.properties,
      ApplicationResources_.properties
    </include> 
    </includes>

嗨，经过一些研发后，我能够通过在 maven pom 文件中添加以下插件来解决这个问题。

<plugin>
   <groupId>org.codehaus.mojo</groupId>
   <artifactId>native2ascii-maven-plugin</artifactId>
   <dependencies>
        <dependency>
             <groupId>com.sun</groupId>
             <artifactId>tools</artifactId>
             <version>1.7.0</version>
             <scope>system</scope>
             <systemPath>${java.home}/../lib/tools.jar</systemPath>
       </dependency>
   </dependencies>
 </plugin>
