It took me a while to figure out how to put multiple entries into an
environment variable (that is, settings for both min and max heap sizes,
to wit, "export JVM_OPTS=\ -Xms4G\ -Xmx4G") but, once I did, Phil's and
Luc's suggestions have worked well and things have gone swimmingly. They
work for
The bash example is
export JVM_OPTS=-Xms4G ...

If you are running in a unix shell, something like
JVM_OPTS=-Xms4G ...
Followed by
export JVM_OPTS
Bash allows you to combine the two as in:
export JVM_OPTS-Xms4G ...
In a windows Cmd shell, something like this should work:
set JVM_OPTS=Xms4G ...
before running lein from the command line.
I should be switching over to Leiningen 2 shortly in any case, but I am
curious. How does one "set JVM_OPTS as an environment variable"?

Also there is an environment variable _JAVA_OPTIONS (note the leading
underscore) which is handled by the HotSpot JVM (OpenJDK or Oracle
JDK) and can be used with any java application.

You could add the following evinroment variable to your OS:
LEIN_JVM_OPTS=-Xms4G -Xmx4G
On Windows for example, you could add at the top of "lein.bat" file the
following line (under "@echo off"):
SET LEIN_JVM_OPTS=-Xms4G -Xmx4G
This should be enough to do the trick.

That blog post is pretty outdated. When using leiningen, you can pass
arbitrary jvm opts via project.clj[1]:
:jvm-opts ["-Xmx1g"]

Oh, sorry, misunderstood your question. I found this blog post, maybe
this still works, although it's from 2010:

Check the sample project.clj on Github:
https://github.com/technomancy/leiningen/blob/master/sample.project.clj
There's an entry for JVM options:
;; You can set JVM-level options here.
:jvm-opts ["-Xmx1g"]
In a quick test, that worked for me when lein repl was executed.
