Repro steps

1. Create a new schematics project using schematics schematic --name=test-schematic.
2. cd test-schematic
3. npm i
4. npm run build
5. schematics .:my-full-schematic --name=test

The log given by the failure

schematics .:my-full-schematic --name=test
    My Full Schematic: {"name":"test","index":1}
            My Other Schematic: {"option":true}
                        My Schematic: {"option":true}
CREATE /hola (5 bytes)
CREATE /allo (5 bytes)
CREATE /test2 (34 bytes)
CREATE /test1 (18 bytes)

You can see above that is at least outputs the --dryRun results, but since I didn't specify --dryRun, it should commit them to disk. I also tried with --dryRun=false but the behavior was the same.

You can see above that there are no files named hola, allo, etc.

Desired functionality

I should be able to run a schematic locally when authoring/testing a schematic and see the output get committed to disk if there are no errors.

Mention any other details that might be useful

I also saw this with @angular-devkit/schematics-cli@0.9.0-rc.2.

@Splaktar I have looked into this, and since the you are running the schematic locally, by default it will be running in a dry run To disable this you need to use --dry-run=false.

I noticed that at the moment only kebab case args are available, I'll do a PR to address this.
