我的环境的设置是 SBT 1.3.0-RC1、Scala 2.12.8 和 Java 1.8.0_212。SBT 在 期间抛出异常compile，

运行命令行 SBT 时发生相同的错误。我该如何解决？谢谢

更新 #1

TL;DR增加 SBT 线程堆栈大小，即 SBT_OPTS="-Xss2m" sbt clean compile

我的项目使用PureConfig并且编译器很重。增加内存占用会清除编译器溢出异常。举个例子，我的案例类在其参数中有一个List或Option嵌套的案例类。巧合的是，嵌套案例类在其构造函数中有一个List或，Option

case class Foo(bars: List[Bar])
case class Bar(name: String, url: Option[URL])

这将导致编译器抛出 StackOverflowException。但是随着 SBT 的额外内存，编译将通过。

sbt使用 -mem 标志运行。

sbt -mem 2048 compile

当我几个月前遇到同样的错误时，这样做解决了我的问题。

如果运行时-mem flag没有帮助，您还可以尝试增加 JVM 堆栈大小。

-Xss256m -Xmx4096m

更新

有时，项目中缺少 build.properties 也会产生stackoverflow错误。如果缺少，请添加：

  build.properties with your sbt-version

更新 2

如果您使用的是 PureConfig

PureConfig 是一个“编译器繁重”的库所以，Scala 编译器缺乏资源来进行如此复杂的推导。所以，试试这个

SBT_OPTS="-Xms512m -Xmx1536m -Xss2m"
