Question

我正在使用scalaxb从XSD生成Scala代码。（特别是我正在使用maven scalaxb插件。）代码生成阶段顺利运行，并且眼睛注视它们，生成的scala文件看起来很好。但是当我尝试编译时，我得到了堆栈溢出：

我正在使用的xsd已经过测试并可以使用jaxb。

Scala版本为2.9.0-1，scalaxb为0.6.2。

Answer 1

因此，根据OP，通过将-Xss2048k放入jvmArg来解决问题。

Answer 2

对于sbt和复杂的xsd，我必须在sbt compile期间使用以下命令将堆栈大小增加到4M：

sbt -J-Xss4M compile

scalaxb生成的代码在编译期间导致堆栈溢出
