Motivation for or Use Case

It should be possible to use generate-sample devBlueprint to generate samples.

Reproduce the error

Create a blueprint for jdl and try running the command
jhipster-<blueprintName> generate-sample sample.jdl

Related issues

None.

Suggest a Fix

Change this to

await this.composeWithBlueprints('jdl', { generatorArgs: (this.options as any).jdlFiles });

similar to language generator

jdl generator can be composed as follows,

await this.composeWithJHipster('jdl', {
          generatorArgs: [this.sampleName],
          generatorOptions: {
            skipJhipsterDependencies: true,
            skipInstall: true,
            jdlFiles: [ this.sampleName ],
          },
        });

[mshima]

The languages implementation was old when args and options were defined in constructor.
#25497 should be a more generic solution.

@dwarakaprasad let me know if the solution is ok.

@dwarakaprasad let me know if the solution is ok.

@mshima this is much better than what I had suggested. I was a little hesitant to use _agrs (although it was used in parseJHipsterArguments) from yeoman. Your solution has fixed the problem for all blueprint generators. This is great and thank you so much.

I tested both cli & generate-sample, both works like a charm. Once again thank you so much...
