如何在eclipse中使用ANT使用jcoverage java工具

我想使用ANT和eclipse为我的单元测试准备jcoverage报告。我正在使用

Apache AntTM版本1.8.3于2012年2月26日编译 selenium-server-standalone-2.20.0 junit-4.8.1.jar EclipseSDK3.6.1 我试过了，就像上面提到的

但我不能成功。请提供任何文件，或让我清楚如何准备报告

我的ant文件：

 <?xml version="1.0"?>

请提供一个解决方案。

错误通知您javac编译器找不到junit JAR。尽管您将junit.class.path指定为编译ant目标中的类路径，但该类路径包含对${libs}属性的引用，而该属性未在build.xml中定义

此外，在使用属性定义之前，您应该移动它们，如lib.dir，例如，在引用${lib.dir}的jcoverage.path的定义之前

---

注意：您可以看到使用-verbose选项调用ant或在任务之前调用${junit.class.path}任务所使用的类路径

按照链接页面上的说明操作时遇到了什么问题？您好，Attila，我在这里添加了我的所有内容。请澄清。taskdef说找不到$lib.dir。您在taskdef中使用了错误的paranthesis。它必须是${lib.dir}@ores。我现在更改了所有这些内容，我得到了jcoverage报告。但它总是只显示0%的覆盖率，我无法运行我的单元测试。我在上面添加了我的ant文件和单元测试文件，这可能会帮助您澄清我的问题。感谢您的回复。我纠正了我的错误。现在我能够生成我的jcoverage报告。但是，它始终只显示0%的覆盖率。我的单元测试刚刚编译，但没有运行。请澄清一下。我认为问题是junit任务的元素引用了${src.dir}目录，它没有*.class文件。您提到的链接列出了${build.test classes.dir}。我也尝试过，但没有成功。报告只显示了0%的覆盖率。
