【问题描述】：

我刚刚从 2.3 迁移到 2.4。应用程序本身似乎正在运行，但没有任何测试将运行。它们都失败并出现以下错误：

我正在使用 InjectedRoutesGenerator 和 webjars-play 的 2.4.0-M3-1 版本。如果还有其他可能有帮助的细节，请告诉我！

有人知道会发生什么吗？

编辑：

挖出来：https://github.com/sbt/sbt-web/issues/104

所以似乎是一个已知问题。我想我会在此期间尝试找到一个创造性的解决方法......

【参考方案1】：

失败的近因是：下有超过5级子目录：

/home/jlei/workspace/ebor-play/target/web/classes/main/META-INF/resources/webjars

See this source file for the source of the error.

【讨论】：

我确实有一些深度超过 5 层的 javascript 文件......我想我只是不明白为什么这是非法的事情？

【参考方案2】：

这是 sbt-web 中的一个问题。他们提高了限制：https://github.com/sbt/sbt-web/issues/104

【参考方案3】：

我通过模拟WebJarAssets 类在测试中解决了这个问题。扩展OneAppPerSuite 或OneAppPerTest 的测试类中的基本虚假应用程序创建代码如下所示：

implicit override lazy val app: Application = new GuiceApplicationBuilder()
    .in(Environment(new File("."), this.getClass.getClassLoader, Mode.Test))
    .bindings(bind[WebJarAssets].toInstance(mock[WebJarAssets]))
    .build

在这里，我还混合了 org.scalatest.mock.MockitoSugar 特征，以便使用 mock 方法。 我不确定功能测试的情况是否需要完全构建的应用程序，其中WebJarAssets 可以使用。
