Question

在IntelliJ中运行Specs2失败。通过SBT任务手动运行相同的测试工作正常，没有任何问题。

消息：＆＃34;测试框架意外退出＆＃34;
IntelliJ ：v.15.0.5或2016.2 EAP（build＃IC-162.426.1）
平台：Scala 2.11.7，SBT 0.13.8，Specs2 2.4.17，播放！ 2.3.10

这是一种常见的错误响应，但看起来很多其他人的根本原因是不同的。我之前已对此问题进行了问题排查，并通过将以下内容添加到build.sbt：

进行了更正

fork in Test := false
parallelExecution in Test := false

现在测试再次失败。我查看了build.sbt文件的修订历史记录，但是我没有注意到会引发这种回归的任何重大事件，而且我没有任何线索。

在步骤调试崩溃后，我找到了以下根本原因：

scalaz.Tree是我项目中许多其他依赖项的传递依赖项，它们请求的版本包括7.1.1，7.1.2，7.1.3，7.0.6 {{1} }}。值得注意的是，在scalaz 7.0.x中有一个特征（Java俗语中的界面），但是scalaz.Tree中的抽象类，所以这可能构成了根本原因。

是否可以解决此问题，因为传递依赖项与scalaz 7.1.x和7.1.x存在明显不兼容的冲突？

Answer 1

Specs2 2.4.17使用Scalaz 7.1.0。构建中的其他依赖项可能会拖动Scalaz 7.2.x依赖项。我建议您将specs2版本更新为3.8.4，这会将更新版本的Scalaz纳入范围。

Specs2测试无法在IntelliJ中本机运行
