Scala [2.11.6]编译Stackoverflow错误（似乎对目前发现的建议不敏感）

Question

scalaVersion：=＆＃34; 2.11.6＆＃34;

我当然多次尝试clean以及update - 不确定是否有clean-deeper来刷新jar（库）。

真正奇怪的是，这种情况同时发生在两台机器上，一台机器没有做任何特殊的事情就恢复了，而另一台机器却没有。我在第二台机器上提升了代码（大约2周的努力），认为这只是抽奖类型异常的一些奇怪的运气，但遗憾的是没有。

如果我无法解决这个问题，我感到害怕！当事情无法编译时，你如何完成工作？

这是野兽的头 - 似乎有时是随机的 - 我需要记录多个快照以确定。尾巴似乎一直都很相似，但是头部开始似乎有点徘徊。

另一个编译尝试的野兽的头 - 所以它似乎有些不确定，表明它可能实际上与记忆有关。 （大多数堆栈溢出可能与逻辑无关，实际上是内存......）

尝试过记忆技巧。

How to prevent java.lang.OutOfMemoryError: PermGen space at Scala compilation?

我的文件在这里：/ Users / garyhewett / Applications / conf / sbtopts

在这里尝试：/.sbtopts按照：

How to set heap size for sbt?

看过这样的事情：https://github.com/lihaoyi/fastparse/issues/8（表示它＆＃34; s＆＃34;不是我的问题＆＃34;然而它实际上现在......）

以下是当前.sbtopt（在项目根目录中）内容

-J-Xmx2G
-J-Xss2G
-J-XX:MaxMetaspaceSize=1G
-J-XX:MaxPermSize=1G
-J-XX:+CMSClassUnloadingEnabled

看来即使是2GB的Stack Space似乎也不能帮助解决这个问题（虽然我想用某种方法来确认这个文件是否被读取）

好帮忙！ （请...）
