Usage: $script_name [options]
Note that options which are passed along to sbt begin with -- whereas
options to this runner use a single dash. Any sbt command can be scheduled
to run first by prefixing the command with --, so --warn, --error and so on
are not special.
-h | -help print this message
-v verbose operation (this runner is chattier)
-d, -w, -q aliases for --debug, --warn, --error (q means quiet)
-x debug this script
-trace <level> display stack traces with a max of <level> frames (default: -1, traces suppressed)
-debug-inc enable debugging log for the incremental compiler
-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)
-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
-script <file> Run the specified file as a scala script
# sbt version (default: sbt.version from $buildProps if present, otherwise $sbt_release_version)
-sbt-version <version> use the specified version of sbt (default: $sbt_release_version)
-sbt-force-latest force the use of the latest release of sbt: $sbt_release_version
-sbt-dev use the latest pre-release version of sbt: $sbt_unreleased_version
-sbt-jar <path> use the specified jar as the sbt launcher
-sbt-launch-dir <path> directory to hold sbt launchers (default: $sbt_launch_dir)
-sbt-launch-repo <url> repo url for downloading sbt launcher jar (default: $(url_base "$sbt_version"))
# scala version (default: as chosen by sbt)
-28 use $latest_28
-29 use $latest_29
-210 use $latest_210
-211 use $latest_211
-212 use $latest_212
-213 use $latest_213
-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 2>&1 | grep version))
-java-home <path> alternate JAVA_HOME
# passing options to the jvm - note it does NOT use JAVA_OPTS due to pollution
# The default set is used if JVM_OPTS is unset and no -jvm-opts file is found
<default> $(default_jvm_opts)
JVM_OPTS environment variable holding either the jvm args directly, or
the reference to a file containing jvm args if given path is prepended by '@' (e.g. '@/etc/jvmopts')
Note: "@"-file is overridden by local '.jvmopts' or '-jvm-opts' argument.
-jvm-opts <path> file containing jvm args (if not given, .jvmopts in project root is used if present)
-Dkey=val pass -Dkey=val directly to the jvm
-J-X pass option -X directly to the jvm (-J is stripped)
# passing options to sbt, OR to this runner
SBT_OPTS environment variable holding either the sbt args directly, or
the reference to a file containing sbt args if given path is prepended by '@' (e.g. '@/etc/sbtopts')
Note: "@"-file is overridden by local '.sbtopts' or '-sbt-opts' argument.
-sbt-opts <path> file containing sbt args (if not given, .sbtopts in project root is used if present)
-S-X add -X to sbt's scalacOptions (-S is stripped)
# passing options exclusively to this runner
SBTX_OPTS environment variable holding either the sbt-extras args directly, or
the reference to a file containing sbt-extras args if given path is prepended by '@' (e.g. '@/etc/sbtxopts')
Note: "@"-file is overridden by local '.sbtxopts' or '-sbtx-opts' argument.
-sbtx-opts <path> file containing sbt-extras args (if not given, .sbtxopts in project root is used if present)
