Error during sbt execution: java.lang.OutOfMemoryError: PermGen space

请帮忙。

Answer 1

您的项目需要更多内存才能执行（这就是java.lang.OutOfMemoryError: PermGen space告诉您的内容）。我从未使用过类型安全堆栈，因此我不知道是否可以直接配置内存参数。

但是如果你运行Linux，你可以输入

env JAVA_OPTS="-Xms512m -Xmx1024m -Xss1M -XX:MaxPermSize=512" <command>

其中command是执行项目的命令（可能是sbt）。当然，如果需要更多/更少的空间，可以更改参数的大小。
