Add --ignore-missing option to nx run to run non-existent targets as noop without failing

[akwodkiewicz]

I'd like to be able to run

nx run --ignore-missing foobar:some-target 

so that Nx will not fail when some-target does not exist on foobar, but just do nothing.

Why?

Obviously I don't want to run foobar:some-target verbatim.

In my Dockerfile, I have the project parametrized ($NX_PROJECT_NAME) and I am reusing the same Dockerfile with multiple projects.

I want to add an additional target that needs to be run during the image build process, but the target will only be specified for some of the projects that use that Dockerfile.

I'd like to add the following line and call it a day:

RUN nx run --ignore-missing $NX_PROJECT_NAME:some-target

However, since there is no flag like this one, I need to parse project configuration which feels very roundabout:

RUN [[ $(nx show project --json $NX_PROJECT_NAME | jq  '.targets | has("some-target")') == 'true' ]] \
  && nx run $NX_PROJECT_NAME:some-target

[akwodkiewicz]

Any combination of composing targets differently with dependsOn does not work for me, because I want this command to be run at a particular point of time.

As a workaround, run-many automatically ignores projects for which the target is not defined, and you can pass just one project to -p:

RUN nx run-many -t some-target -p $NX_PROJECT_NAME
