我正在使用 SBT 0.12.3 测试一些代码，并且经常在使用~test命令进行交互测试时收到此错误消息。

错误很明显，我增加了堆大小，它可能会停止抛出该错误，但问题是它在进行了一些（我不知道有多少）测试交互后关闭，代码的变化很小，如果简单地增加堆就可以解决问题，或者我是否必须做额外的工作才能避免内存不足。

提前致谢。

如果还没有，请尝试在 sbt.bat 中提供更多 PermGen 空间。我不在 Windows 上运行 sbt，但我提供java -Xmx1512M -XX:MaxPermSize=512M.

另一件要尝试的事情可能是在测试期间分叉：https ://www.scala-sbt.org/1.x/docs/Testing.html#Forking+tests

Test / fork := true

指定所有测试都将在单个外部 JVM 中执行。
