Errors when plugin is used in a preset

[bodograumann]

When creating a vue project with the following preset:

{
  "plugins": {
    "vue-cli-plugin-component": {
      "prompts": true
    }
  }
}

and answering no to all the questions, there is no new content added to the readme file. Also the asset directory is not deleted.

Could you detail the step bu step scenario please; Thanks

[bodograumann]

Sure. Have vue-cli-3 installed. Create a file called component-preset.json with the content

{
  "plugins": {
    "vue-cli-plugin-component": {
      "prompts": true
    }
  }
}

Then call vue create --preset component-preset.json test-component. Give the component name and answer no to all the questions. (Alternatively you could probably remove "prompts": true in the preset and predefine the name instead, but I did not look up what the name setting is called for your plugin.)

Tried to reproduce today your scenario with last version of the plugin: everything worked.

[bodograumann]

That is weird. Are you certain? This is what I get with the latest version 1.10.5:

[…]
🚀  Invoking generators... 
                   
vue-cli-plugin-component
? Enter the component name (in PascalCase- no hyphen nor dash): TestComponent
? Use componentFixture to build example? No
? Use vue-styleguidist to generate documentation? No
? Use vuedoc.md to automatically generate README API section? No
? Add project badges to README.md? No
? Add license? No
File not found README.md
📦  Installing additional dependencies...

Note the “File not found README.md”.

I’m on node v8.12.0, if that has anything to do with it…

What Os? Linux I guess?

[bodograumann]

Yes: Linux 4.17.19-gentoo

[David-Desmaisons]

Which version of vue-cli? If it is not the last one, could you please update your vue-cli version and try to reproduce?

[bodograumann]

It is the latest version: @vue/cli@3.2.1
I just did do npm update -g.

[bodograumann]

Please try my reproduction: https://github.com/bodograumann/component-plugin-test
It seems to me, that vue-cli is generating the README.md only after the plugin generators have been run.
At least for preset generators I know it is possible to postpone running some modifications with api.onCreateComplete(mycallback). Maybe this is needed here as well.

There are also several differences in comparison to using vue add component afterwards:

• README.md and App.vue are not changed
• No assets and components directories under src
