Java 无法在fat/uber jar中找到或加载主类

我有一个java项目，它有spring依赖项。我正在通过ANT构建一个jar文件，如下所示

<jar jarfile="Test.jar">
    <manifest>
        <attribute name="Main-Class" value="com.karthik.EntryPoint"/>
    </manifest> 
    <fileset dir="${build.classes.dir}" includes="**" />
</jar>

Error: Could not find or load main class com.karthik.EntryPoint

为了解决这个问题，我创建了一个fat/uber jar，它具有所有spring依赖项，如下所示：

<jar jarfile="Test.jar">    
     <zipgroupfileset dir="${build.dir}/lib" includes="spring*.jar" />  

     <manifest>
         <attribute name="Main-Class" value="com.karthik.EntryPoint"/>
     </manifest>    

     <fileset dir="${build.classes.dir}" includes="**" />
     <fileset dir="${src.java.dir}" includes="**/*.java" />
</jar>

为什么我只在uber/fat jar中收到此错误，我们如何解决它？

请任何人帮助我解决此错误。请任何人帮助我解决此错误。
