-v | -verbose this runner is chattier
|

-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_default_mem, which is $(get_mem_opts))
|
||||
-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
|

.jvmopts if this file exists in the current directory, its contents

are appended to JAVA_OPTS

SBT_OPTS environment variable, if unset uses "$default_sbt_opts"

.sbtopts if this file exists in the current directory, its contents
|

are 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.
