蚂蚁1.9.2+JUnit..类未找到错误

Question

我使用的是JDK 1.7，eclipse 4.2.2、JUnit 4.8.1、ant 1.9.2、windows8 64位**。当我运行build.xml时，所有目标都运行良好，但名称为run的目标运行不佳。

必须将编译后的类添加到junit任务的类路径中。

    <junit fork="yes" haltonfailure="no" printsummary="yes" >
    <classpath>
      <path refid="testcase.path">
      <pathelement location="${test.dest}"/>
    </classpath>
    <batchtest todir="${test.reportsDir}" fork="true">
      <fileset dir="${test.dest}">
        <include name="anttestcase/Login.class"/>
      </fileset>
    </batchtest>
    <formatter type="xml"/>
  </junit>

在Github上有一个示例ant项目，它使用JUnit:https://Github.com/mplacona/java-junit-template-project查看它的build.xml。
