I created a new Micronaut from the CLI and tinkered around a bit then realized that I could add features from the cli but it seems to only be an option when calling create-app.
Is there a way to add features from the command line after the app has been created?
Unfortunately no, the CLI is limited to project-generation commands (create-app, create-federation) and code-generation (commands like create-controller and create-client). It does not have the ability to modify existing projects at this time.
Micronaut CLI has a new command: feature-diff that produces the diff of an original project with an original project with additional features specified as a parameter.
Example of a command with reactor feature:
mn feature-diff --features=reactor
Which generates something like this:
You can store the differences in a file and apply it to your project:
mn feature-diff --features=reactor > reactor-features.diff
patch -i reactor-features.diff
Note Micronout CLI provides -f, --force option to override existing files, however, that option didn't work for me, hence patch option as a workaround.
