找不到类。.java.lang.ClassNotFoundException：

Question

我看过很多帖子，但是没有一个帮助！在为测试类运行JUnit测试时出现以下错误：

java.lang.ClassNotFoundException: com.company.project.abc.pqr.AbcTest
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338)
at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:460)
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:206)

它通过控制台运行测试，但是由于我想调试测试，因此我需要通过Eclipse进行测试。你能建议我该怎么办？

我尝试过：

  

再次构建

     

禁用Maven Nature，然后启用Maven Nature

     

Maven更新项目

     

mvn eclipse：eclipse

     

mvn eclipse：clean

     

将此添加到.project文件

 <buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
 </buildSpec>
 <natures>
    <nature>org.eclipse.jdt.core.javanature</nature>
 </natures>

编辑： 为测试类添加了运行配置：

.classpath文件：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" output="target/classes" path="src/main/java">
    <attributes>
        <attribute name="optional" value="true"/>

    </attributes>
</classpathentry>

我想在我的pom罐子中添加包装。     罐子
