experimental_run_shell_command

Run a script in the workspace, with all dependencies packaged/copied into a chroot.

Example BUILD file:

experimental_run_shell_command(
  command="./scripts/my-script.sh --data-files-dir={chroot}",
  dependencies=["src/project/files:data"],
)

The command may use either {chroot} on the command line, or the $CHROOT environment variable to get the root directory for where any dependencies are located.

In contrast to the experimental_shell_command, in addition to workdir you only have the command and dependencies fields as the tools you are going to use are already on the PATH which is inherited from the Pants environment. Also, the outputs does not apply, as any output files produced will end up directly in your project tree.

Backend: pants.backend.shell

command

type: str
required

Shell command to execute.

The command is executed as 'bash -c ' by default.

dependencies

type: Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].

This augments any dependencies inferred by Pants, such as by analyzing your imports. Use ./pants dependencies or ./pants peek on this target to get the final result.

See Targets and BUILD files#target-addresses and Targets and BUILD files#target-generation for more about how addresses are formed, including for generated targets. You can also run ./pants list :: to find all addresses in your project, or ./pants list dir: to find all addresses defined in that directory.

If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description

type: str | None
default: None

A human-readable description of the target.

Use ./pants list --documented :: to see all targets with descriptions.

tags

type: Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.

workdir

type: str | None
default: '.'

Sets the current working directory of the command, relative to the project root.
