sbt temporary directories

[Nikolay Botev]

I started using sbt recently, and I see tons of directories under my
USERHOME directory, like this:

c:/users/nikolay/sbt_xxxx

also there are all these sbt_XXXXXXXXXX.log files there.

None of these appears to be needed and I have been removing them.
After actively using sbt for a day or so though, I had 150+ sbt
directories in my home.

Is there a way to configure sbt to use a different (%TEMP%) directory
for its logging/transient data?

I googled a bit but could not find anything online. I also did read
through the entire getting started guide but I did not find any
mention of sbt temp directories and configuring them.

Thanks,

sbt uses the standard temporary directory given by the java.io.tmpdir system property. I don't know why Java has your home directory as the temporary directory, but the java.io.tmpdir property is what you should look into.

Mark,

Thanks for the reply. I nailed the problem down to running sbt without
the TEMP or TMP environment variables set.

I run sbt on Windows from a cygwin bash shell and, for some reason,
neither TMP nor TEMP is set in cygwin. When neither TMP nor TEMP is
set, Java defaults java.io.tmpdir to my home directory.

The problem happens whether I use a bash script or batch file
launcher, as long as I am inside a cygwin bash shell.

I use a bash script, so I simply added the following to the java sbt
command:

-Djava.io.tmpdir="$LOCALAPPDATA\\Temp\\"

and life is good (the LOCALAPPDATA directory is present in cygwin).

While at it, another customization I had to do to get sbt running
within cygwin was to set the jline terminal to Unix explicitly as
described here http://stackoverflow.com/questions/8123949/sbt-cant-run-interactively-from-mintty-on-cygwin

Thanks,

In the spirit of "everything is a Setting", shouldn't this be a Setting ?

I found that in learning SBT, once I started to systematically translate questions like  :

  "How can I do X"

into

  "What is the sbt.Key of the setting that I need to override to achieve X"

things have become more pleasant.
