我有以下if(!any(dplyr::between(A,7.8,8.2))) A <- c(A,8.01)
if(!any(dplyr::between(B,7.8,8.2))) B <- c(B,8.01)
build.xml但是，当我运行构建时，我的覆盖率为0％。

目标，我相信一切都很好。但是当构建运行instrument目标时，测试失败。不知道为什么会这样。如果我在Test之外运行测试，那么它就会成功。
有什么建议我可以解决这个问题？
运行ant目标
test答案 0 :(得分：0)
最后我找到了一个解决方案（不回答）
在跟踪Junit报告后，我发现它与Junit依赖关系有关。
我刚刚从构建路径中删除了Junit-4库，并将Junit-4.7.jar添加到Build路径中，你知道它的工作原理..
如果有人解释我为什么会这样，我会非常感激。
如果我再次使用Junit-4.11.jar失败。报告中的Junit错误显示error message="org/hamcrest/SelfDescribing" type="java.lang.NoClassDefFoundError">java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing
