jbuilder-build man page
jbuilder-build — Build the given targets, or all installable targets if none are given.
jbuilder build [OPTION]... [TARGET]...
Targets starting with a @ are interpreted as aliases.
- -f, --force
Force actions associated to aliases to be re-executed even if their dependencies haven't changed.
- --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.
Show version information.
These options are common to all commands.
Automatically promote files. This is similar to running jbuilder promote after the build.
Load this configuration file instead of the default one.
Always print exception backtraces.
In case of error, print the dependency path from the targets on the command line to the rule that failed.
Debug the findlib sub-system.
Use stricter compilation flags by default.
Shell command to use to diff files
Control the display mode of Jbuilder. See dune-config(5) for more details.
Ignore rules with (mode promote)
- -j JOBS
Run no more than JOBS commands simultaneously.
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.
Do not load the configuration file
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 --promote ignore --no-config. 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.
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.
Same as --display verbose
Use this specific workspace file instead of looking it up.
- -x VAL
Cross-compile using this toolchain.
Use `jbuilder COMMAND --help' for help on a single command.
