Usage: $script_name [options]
-h | -help print this message
-v | -verbose this runner is chattier
-d | -debug set sbt log level to debug
-no-colors disable ANSI color codes
-sbt-create start sbt even if current directory contains no sbt project
-sbt-dir <path> path to global settings/plugins directory (default: ~/.sbt)
-sbt-boot <path> path to shared boot directory (default: ~/.sbt/boot in 0.11 series)
-ivy <path> path to local Ivy repository (default: ~/.ivy2)
-mem <integer> set memory options (default: $sbt_mem, which is $(get_mem_opts $sbt_mem))
-no-share use all local caches; no sharing
-no-global uses global caches, but does not use global ~/.sbt directory.
-jvm-debug <port> Turn on JVM debugging, open at the given port.
-batch Disable interactive mode
# sbt version (default: from project/build.properties if present, else latest release)
-sbt-version <version> use the specified version of sbt
-sbt-jar <path> use the specified jar as the sbt launcher
-sbt-rc use an RC version of sbt
-sbt-snapshot use a snapshot version of sbt
# java version (default: java from PATH, currently $(java -version 2>&1 | grep version))
-java-home <path> alternate JAVA_HOME
# jvm options and output control
JAVA_OPTS environment variable, if unset uses "$java_opts"
SBT_OPTS environment variable, if unset uses "$default_sbt_opts"
.sbtopts if this file exists in the current directory, it is
prepended to the runner args
/etc/sbt/sbtopts if this file exists, it is prepended to the runner args
-Dkey=val pass -Dkey=val directly to the java runtime
-J-X pass option -X directly to the java runtime
(-J is stripped)
-S-X add -X to sbt's scalacOptions (-S is stripped)
In the case of duplicated or conflicting options, the order above
shows precedence: JAVA_OPTS lowest, command line options highest.
