Eclipse/Maven：“无法找到主类”错误虽然构建可执行文件JAR

Question

更新：“找不到主类”原来是一个红鲱鱼：在public static void main(String[] args)之前，我的班级尝试从未包含在JAR中的文件加载资源束。未能加载此资源所产生的报告，导致我错了方向：

Caused by: java.util.MissingResourceException: Can't find bundle for base name propFile, locale en_US 
     at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1427) 
     at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1250) 
     at java.util.ResourceBundle.getBundle(ResourceBundle.java:705) 
     at com.foo.bar.MyApp(MyApp.java:103) 
Could not find the main class: com.foo.bar.MyApp. Program will exit. 

我在Win 7开发与Eclipse朱诺和JDK 1.6_45，32位64位。我使用mvn clean install调用生成可执行JAR。

当我尝试启动我收到应用程序“找不到主类”或“无法加载主类清单属性” 类似的地面已经覆盖here和here。我已经阅读了这些答案和basic maven examples，但我仍然没有通过可执行JAR结束 。

我试图既java -jar MyApp-jar-with-dependencies和java -cp MyApp-jar-with-dependencies com.foo.bar.MyApp调用执行应用程序

我觉得特别困惑的MANIFEST.MF（在JAR中的META-INF内contined）专门列出我的目标主类，和MyApp.class文件存在于目录树中正确的位置（com \ foo \ bar \ MyApp.class）。

在开发过程中，我重构了几次包名和类名。这个动作可能导致了一些引用/类路径呃逆？主要班级查找失败的地方还有哪些地方？

我不知道为什么你不工作，这里是一个cut-从我工作的maven项目中粘贴n贴。您应该只需更换com.pictureu.mains.MainGui与您的主要类别进行测试

 <plugin> 
      <artifactId>maven-assembly-plugin</artifactId> 
      <configuration> 
      <archive> 
       <manifest> 
       <mainClass>com.pictureu.mains.MainGui</mainClass> 
       </manifest> 
      </archive> 
      <descriptorRefs> 
       <descriptorRef>jar-with-dependencies</descriptorRef>
