我正在尝试使用Cobertura插件为Jenkins获取代码覆盖率，因此我在build.xml中运行测试然后覆盖报告，如下所示

问题在于，当它试图运行单元测试时（我可以使用ant test运行），它一直在说
module-test:
Running test cases...
Running coberturaandjenkins.CoberturaAndJenkinsTest
Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec
Test coberturaandjenkins.CoberturaAndJenkinsTest FAILED
我已经更改，重新更改，重新更改build.xml几天没有任何运气。我无法让它发挥作用。拜托，我很感激这里的任何帮助。这是我第一次使用ant（和Cobertura）
答案 0 :(得分：2)
感谢你们的所有答案。经过进一步调查，我想出了如何使其发挥作用。我不得不完全重写build.xml。这是：
<property file="build.properties" />
