NAME

       jbuilder-build - Build the given targets, or all installable targets if none are given.

SYNOPSIS

       jbuilder build [OPTION]... [TARGET]...

DESCRIPTION

       Targets starting with a @ are interpreted as aliases.

OPTIONS

       --help[=FMT] (default=auto)
           Show this help in format FMT. The value FMT must be one of `auto', `pager', `groff' or
           `plain'. With `auto', the format is `pager` or `plain' whenever the TERM env var is
           `dumb' or undefined.

       --version
           Show version information.

COMMON OPTIONS

       These options are common to all commands.

       --debug-backtraces
           Always print exception backtraces.

       --debug-dependency-path
           In case of error, print the dependency path from the targets on the command line to
           the rule that failed.

       --debug-findlib
           Debug the findlib sub-system.

       --dev
           Use stricter compilation flags by default.

       -j JOBS (absent=4)
           Run no more than JOBS commands simultaneously.

       --no-buffer
           Do not buffer the output of commands executed by jbuilder. By default jbuilder buffers
           the output of subcommands, in order to prevent interleaving when multiple commands are
           executed in parallel. However, this can be an issue when debugging long running tests.
           With --no-buffer, commands have direct access to the terminal. Note that as a result
           their output won't be captured in the log file. You should use this option in
           conjunction with -j 1, to avoid interleaving. Additionally you should use --verbose as
           well, to make sure that commands are printed before they are being executed.

       --only-packages=PACKAGES
           Ignore stanzas referring to a package that is not in PACKAGES. PACKAGES is a
           comma-separated list of package names. Note that this has the same effect as deleting
           the relevant stanzas from jbuild files. It is mostly meant for releases. During
           development, it is likely that what you want instead is to build a particular
           <package>.install target.

       -p PACKAGES, --for-release-of-packages=PACKAGES
           Shorthand for --root . --only-packages PACKAGE. You must use this option in your
           <package>.opam files, in order to build only what's necessary when your project
           contains multiple packages as well as getting reproducible builds.

       --root=DIR
           Use this directory as workspace root instead of guessing it. Note that this option
           doesn't change the interpretation of targets given on the command line. It is only
           intended for scripts.

       --verbose
           Print detailed information about commands being run

       --workspace=FILE
           Use this specific workspace file instead of looking it up.

MORE HELP

       Use `jbuilder COMMAND --help' for help on a single command.
