当尝试在build.xml中使用runtestsreport任务从ANT运行我的JUnit测试时，我遇到java.lang.NoClassDefFoundError问题；我知道其他任务有效，这只是测试的实际运行是问题所在。
我已根据此处发布的问题尝试了许多调整，但无法解决。我真正需要的是一个与之配对的开发人员，但他们今天都忙着回家。
有人可以帮忙吗？
build.xml文件是

我收到此错误（以及每个测试类的此类错误）

我已经在-verbose模式下运行过ant来检查类路径，但是我看不到问题（即使我知道它在盯着我）

任何帮助我使测试运行的人将不胜感激。

更新资料
我观察到，如果我编辑tests.classpath删除以下两行，那么我看到的错误将切换到ClassNotFound，这很有意义，因为它没有对包含类的.jar文件的引用。
<fileset dir="${testsbuild}/jar" includes="**/*.jar"/>
<fileset dir="${frameworkbuild}/jar" includes="**/*.jar"/>
上面的2行出现在tests.classpath中，可以很高兴地找到它们，但是名称错误，并且是那个错误，我不知道如何解决。
最佳答案
以下jar命令引起的问题：
<jar destfile="${testsbuild}/jar/tests.jar" basedir="${testsbuild}" />
testsbuild属性应设置为
<property name="testsbuild" location="C:\<path on my machine>\workspace\ESS\build"/>
说明
文件Credentials.class被编译为类esstestapp.tests.Credentials。需要在类路径中找到它作为文件：
esstestapp / tests / Credentials.class
