如何在 Intellij IDEA 中高速运行 scala 项目？

Question

How to run a scala project at high speed in Intellij IDEA? I wrote a scala project that uses Figaro libraries, but when I run it in Intellij IDEA, the execution speed is slow and gives a "OutOfMemoryError: Java heap space" error. I want to know how this problem can be solved?

Answer 1

You should probably look into how are you allocating memory. If you have too many references to objects (specially larger ones) you wil run into this problem.

As a quick fix you can add -Xmx to the run configuration arguments to set the heap size to the max possible given the OS. In windows I believe it's 2GB while the java default is much smaller.

Anyways if you don't follow the first advice, you will run into this problem again.
