尝试从ANT运行JUnit测试时出现noclassdeffoundererror错误

Question

当尝试使用以下build.xml中的runtestsreport任务从ANT运行我的JUnit测试时，我遇到了java.lang.NoClassDefFoundError问题;我知道其他任务可以正常工作，问题在于测试的实际运行。

我已经尝试了很多调整基于问题张贴在这里，但我不能解决它;我真正需要的是一个可以搭档的开发人员，但他们都回家了。

有人能帮忙吗?

我得到这个错误(每个测试类都有这种类型的错误)

Credentials (wrong name: esstestapp/tests/Credentials)
java.lang.NoClassDefFoundError: Credentials (wrong name: esstestapp/tests/Credentials)

我已经在-verbose模式下运行了ant来检查类路径，但我看不到问题(即使我知道它就在我面前)

任何能帮助我运行测试的人都将非常感激。

我观察到如果我编辑测试。然后我看到的错误切换到ClassNotFound，这是有意义的，因为它没有引用包含类的.jar文件。

<fileset dir="${testsbuild}/jar" includes="**/*.jar"/>
<fileset dir="${frameworkbuild}/jar" includes="**/*.jar"/>

在测试中出现上述2行。classpath是高兴地发现他们，但错误的名称，这是错误，我不知道如何修复。

Answer 1

由以下jar命令引起的问题:

<jar destfile="${testsbuild}/jar/tests.jar" basedir="${testsbuild}" />

testsbuild属性应该设置为

<property name="testsbuild" location="C:<path on my machine>workspaceESSbuild"/>

文件Credentials.class被编译为类esstestapp.tests.Credentials。它需要在类路径中找到，如文件:

esstestapp/测试/Credentials.class
