Frequently asked questions.
1 . I have an existing Java project and I wish to add Scala files. How do I convince Eclipse to work with Scala?
Right click on the project in the Package Explorer view, and in the popup menu select
Configure -> Add Scala Nature.
2 . I am running out of stack space in Eclipse. How do I increase the stack size?
If you are starting Eclipse from the command line, you can supply vm args, including stack size, like this:
eclipse [normal arguments] -vmargs -Xss8M [more VM args]
You can also edit eclipse.ini in the Eclipse installation/application. There, lines that look like
-vmargs -Xms40m -Xmx256m
can be replaced with something like (for an 8 megabyte stack, 700MB initial heap, 2GB maximum heap)
-vmargs -Xss8m -Xms700m -Xmx2048m
3 . I am using m2eclipse and Scala IDE complains about 'no scala library...' or 'More than one scala library...'
In Scala IDE 2.0, a classpath validator has been added and it reports problem with project imported using m2eclipse. The m2eclipse-scala project was created to, among other things, fix these classpath problems. It is available here.
