Usage: $script_name [options]
-h | -help print this message
-v | -verbose this runner is chattier
-d | -debug set sbt log level to Debug
-q | -quiet set sbt log level to Error
-trace <level> display stack traces with a max of <level> frames (default: $default_trace_level)
-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/<version>)
-sbt-boot <path> path to shared boot directory (default: ~/.sbt/boot in 0.11+)
-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
-offline put sbt in offline mode
-jvm-debug <port> Turn on JVM debugging, open at the given port.
-batch Disable interactive mode
-prompt <expr> Set the sbt prompt; in expr, 's' is the State and 'e' is Extracted
# sbt version (default: from project/build.properties if present, else latest release)
!!! The only way to accomplish this pre-0.12.0 if there is a build.properties file which
!!! contains an sbt.version property is to update the file on disk. That's what this does.
-sbt-version <version> use the specified version of sbt
-sbt-jar <path> use the specified jar as the sbt launcher
-sbt-snapshot use a snapshot version of sbt
-sbt-launch-dir <path> directory to hold sbt launchers (default: $sbt_launch_dir)
# scala version (default: as chosen by sbt)
-28 use $latest_28
-29 use $latest_29
-210 use $latest_210
-scala-home <path> use the scala build at the specified directory
-scala-version <version> use the specified version of scala
-binary-version <version> use the specified scala version when searching for dependencies
# java version (default: java from PATH, currently $(java -version |& grep version))
-java-home <path> alternate JAVA_HOME
# jvm options and output control
JAVA_OPTS environment variable holding jvm args, if unset uses "$default_jvm_opts"
SBT_OPTS environment variable holding jvm args, if unset uses "$default_sbt_opts"
.jvmopts if file is in sbt root, it is prepended to the args given to the jvm
.sbtopts if file is in sbt root, it is prepended to the args given to **sbt**
-Dkey=val pass -Dkey=val directly to the jvm
-J-X pass option -X directly to the jvm (-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.
