Make plugin compatible with Matomo 4

[Findus23]

Hi, hope you are doing well!

Matomo 4 is progressing steadily and it would be great if this plugin was also available for it.

Migrating the plugin should be pretty simple as there were not many breaking changes.

You can find the migration guide here: https://developer.matomo.org/guides/migrate-matomo-3-to-4

It boils down to:

• update your dev environment to 4.x-dev
• update your plugin.json (new major version of the plugin and require >=4.0.0-b1,<5.0.0-b1)
• check that everything still works fine
• commit this to a new branch (e.g. 4.x-dev) and make this branch the default in the github settings
• tag and push a new release to publish it to the marketplace

If you later fix a bug and also want to backport it to the 3.x plugin, you can cherry-pick the commit to the old branch, release a new version (lower than the one for 4.x) and publish it and 3.x users should get this update.

If you have questions about anything, just ask me!

I have released version 2.0.0, which is compatible with Matomo 4.

@Findus23 I had problems running the tests on Travis, as both the minimum and maximum supported version do not exist yet. Setting PIWIK_TEST_TARGET=4.x-dev in .travis.yml fixed the problem. Maybe you want to mention this in your howtos.

Also, on this documentation page, https://developer.matomo.org/guides/tests-php you propose to use ./console generate:test. However, the verb generate:test seems to have disappeared from the console, in 4.x-dev. Is there an alternative?

Many thanks for the update.

I forwarded this to the team.

Are you sure? For me it seems to work. Make sure you have the development mode enabled as otherwise all development commands are not available. (./console development:enable)

Indeed, enabling developement mode helped. I was confused as e.g. generate:travis-yml is available even when development mode is disabled. Is that one useful for non-developers?
