playframework - 如何将 Play 2.4.x 与 scalaz 7.2.0 一起使用

Question

似乎是specs2的版本问题。

下面是我编译测试时的错误:

[error] Uncaught exception when running ServiceSpec: java.lang.IncompatibleClassChangeError: Found class scalaz.Memo, but interface was expected
[trace] Stack trace suppressed: run last test:test for the full output.
[error] Uncaught exception when running ApplicationSpec: java.lang.NoClassDefFoundError: Could not initialize class org.specs2.main.Arguments$
[trace] Stack trace suppressed: run last test:test for the full output.
[error] Uncaught exception when running IntegrationSpec: java.lang.NoClassDefFoundError: Could not initialize class org.specs2.main.Arguments$
[trace] Stack trace suppressed: run last test:test for the full output.
[error] Uncaught exception when running FileImportSpec: java.lang.NoClassDefFoundError: Could not initialize class org.specs2.main.Arguments$
[trace] Stack trace suppressed: run last test:test for the full output.

有解决办法吗？

Answer 1

TLDR；找不到解决方法，所以我将其降级

问题不在于 Play，而在于 specs2。我的 specs2 版本使用:scalaz-core 版本 7.1.1。您可以使用 sbt dependency graph plugin 找到您自己的(该插件似乎隐藏了测试范围的依赖项:从 specs2 依赖项中删除 test 范围)

我不得不将 scalaz-core 版本降级到 7.1.1

  "org.scalaz" %% "scalaz-core" % "7.1.1"
