【问题描述】：
我最近开始在一个新地方工作，他们正在使用 scala 并玩这个旧版应用程序。不幸的是，这里没有人熟悉这个错误，我希望一些更有经验的 scala 人可以在这里发光。
在 Mac OS (Catalina) 上，我遇到了这些错误，但是当我将所有内容放入 linux VM 时，我可以让它工作！所以，它是特定于 OS X 的。
Java 8 SBT .13
以下是尝试运行程序时来自 SBT 控制台的几个堆栈跟踪：

【问题讨论】：
-
我已经尝试更改我正在使用的 JVM，甚至擦除我的磁盘并降级回 Mojave，我认为因为本机方法没有签名，所以它们不能执行。我还是迷路了。
-
这使用的是什么版本的 Play？我有一个类似的，如果不是相同的堆栈跟踪，还不能弄清楚问题是什么。我在玩
2.6.20。 -
我现在已经设法通过删除 ~/.ivy2 并重新开始来重新创建您的第二个堆栈跟踪。我很想知道您尝试过哪些 JVM。我一直在使用采用 OpenJDK 1.8.0_242。我遇到了建议尝试 232 的 this post，突然问题对我来说消失了。
-
使用 play 2.5.18
