An alternative script for running [sbt 0.10](https://github.com/harrah/xsbt).

|
|
|
There's also a template project sbt coming together, but it's unfinished.
|
|
|
|
|
However the runner is quite useful already.

|
|
Here's a sample first run, which uses a shared boot directory and a local scala.
|
|
|
|
|
|
|
|
|
|
% ./sbt -shared /tmp/bippy -local /scala/inst/3 run
|
|
|
|
|
Downloading sbt launcher, this should only take a moment...

Adding -debug to the same command line reveals the command line arguments:

# passing options to jvm
|
|
|
|
|
JAVA_OPTS environment variable # default: "-Dfile.encoding=UTF8"
|
|
|
|
|
SBT_OPTS environment variable # default: "-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=512m -Xmx2g -Xss2m"
|
|
|
|
|
-Dkey=val pass -Dkey=val directly to the jvm
|
|
|
|
|
-J-X pass option -X directly to the jvm (-J is stripped)
|
|
|
|
|
|
|
|
|
|
The defaults given for JAVA_OPTS and SBT_OPTS are only used if the
|
|
|
|
|
corresponding variable is unset. In the case of a duplicated option,
|
|
|
|
|
SBT_OPTS takes precedence over JAVA_OPTS, and command line options
|
|
|
|
|
take precedence over both.
