Kibana plugin helpers error

Elastic Stack Kibana

Hi,

I developed a kibana plugin for kibana version 7.9.0. I setup the development environment following this.

Now I want to generate the zip of the developed plugin. I tried follow the steps mentioned here but while running the following command yarn add --dev link:../../kibana/packages/kbn-plugin-helpers

I get the following error:
OS: System Linux 5.8.11-1-MANJARO

if I run the same command i.e., yarn add --dev link:../../kibana/packages/kbn-plugin-helpers again it succeeds. But then I get an error in the next step:

command: yarn kbn bootstrap

[user@user kibana]$ yarn kbn bootstrap
yarn run v1.22.5
$ node scripts/kbn bootstrap
ERROR [bootstrap] failed:
ERROR [kibana] depends on [@kbn/plugin-helpers] but should be using a workspace. Update its package.json to the expected value below.

 │      package: kibana (/home/chaitanya/projects/7.9/package.json)
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

if I do the changes to package.json as suggested in the error, bootstrapping succeeds. but plugin-helpers command is still not available.

so I run this node node_modules/@kbn/plugin-helpers/bin/plugin-helpers where I can find the plugin helpers.

After this I get this error:

Task "build" failed:

Hey @K_Chaitanya!

We've made a lot of changes to plugins recently, and things are all fixed up and working great in 7.10. Would you mind checking out the 7.x branch of the Kibana repo, generating a new plugin with node scripts/generate_plugin, and then moving your code over to that new plugin? (it will be located in the plugins directory of the Kibana checkout)

You should be able to create a build of your plugin that is installable in 7.9, and hopefully the APIs your plugin uses will work in 7.9 as well, but you should have better luck moving forward if you adopt the 7.10 way of doing things now rather than waiting for it to be released.

In 7.10, since plugins are developed within the Kibana repo, you don't need to install packages like @kbn/plugin-helpers. Instead you can just import then and they will be available because the Kibana node_modules directory is in a parent directory of your plugin.

Thank you @spalger, it worked like a charm.
