我有一个春天的 Maven 项目。我们也有很多 JUnit 测试类。我们正在使用 Eclipse。时不时地 - 实际上经常 - eclipse 将一些（不是全部）测试类显示为红色......声称它无法找到导入。查看 Eclipse 错误日志，我可以看到很多这些错误消息（但对于不同的测试类 ofc）。

怎么了？我在同一个项目中工作的同事没有收到此错误。我们正在使用 Eclipse Juno SR2。

问题可能出在 jars 依赖项中（特别是如果您使用的是模拟）。您需要执行两个步骤来找出问题所在：

1.使用maven运行单元测试（如果它工作你可以去step2）；2. 在 Eclipse 中查看 jars 顺序（项目设置-> java 构建路径-> 顺序和设置）。

如果您说它适用于您的同事，您需要将您的罐子的顺序与您同事的罐子的顺序进行比较
