My application does large data arrays processing and needs more memory than JVM gives by default. I know in Java it's specified by "-Xmx" option. How do I set SBT up to use particular "-Xmx" value to run an application with "run" action?
How to specify JVM maximum heap size "-Xmx" for running an application with "run" action in SBT?

sbt lets you list the JVM options you need to run your project on a file named
.jvmopts
in the root of your project. then add the java options that you want
cat .jvmopts
-Xms512M
-Xmx4096M
-Xss2M
-XX:MaxMetaspaceSize=1024M
it is tested and works in windows 10 https://www.lagomframework.com/documentation/1.4.x/scala/JVMMemoryOnDev.html
