我们首先在maven中包装我们的ant构建，开始转向maven .
我们可以让maven构建项目，但不能运行测试 . 我们正在尝试从maven在build.xml中执行ant测试目标 . 当然，当我们从ant运行测试目标时，一切都很好 .
以下是为一个测试类显示的错误（对于其他测试类相同） . 这个类中有几个测试方法，但没有一个正在运行 . 这似乎是一个JUnit版本的问题;测试是JUnit 4测试，如果我们更改测试类以扩展TestCase（JUnit 3样式），它会找到测试 .

UPDATE:
那么，当我们告诉它使用JUnit 4时，为什么maven会运行JUnit 3？我运行了mvn -X测试，看到JUnit 3.8.1 jar因某种原因被拉入，但我不知道如何找出原因 .
UPDATE:
我发现maven antrun插件取决于junit 3.8.1 http://maven.apache.org/plugins/maven-antrun-plugin/dependencies.html
这就解释了Junit 3如何被吸引进来 .
那我现在该怎么办？有没有办法使用maven antrun插件通过build.xml中的ant任务运行我的JUnit 4测试？

这不是问题的直接答案，而是我处理问题的建议（因此我首先将其作为评论）：
不应该通过包装 Ant 目标来移动到maven . 尝试（至少）采用maven standard directory layout . 如果您不能这样做，请尝试通过配置更改标准maven测试源directoy（覆盖Supor POM设置） . 最后使用maven build lifecycle进行编译和测试 .
不确定您是否仍需要解决此问题，但我们遇到了类似的问题 .
您可以使用
junit.framework.JUnit4TestAdapter类在Junit 3测试运行器中运行Junit 4测试 .因此，使用您的测试类作为示例，您只需将以下方法定义添加到类中：
然后测试应该在maven中运行 .
此解决方案的缺点是您需要将
suite()方法添加到所有测试类中 .
