@ThePsina - I'd suggest to please give clear repro steps and mention clearly what you have done, what you expect, and what did you see. Thanks.

[ThePsina]

step: try to compile app with "github.com/mattermost/mattermost-plugin-apps/apps" lib
in go.mod i have this:

	github.com/mattermost/go-i18n v1.11.1-0.20211013152124-5c415071e404 // indirect
	github.com/mattermost/ldap v3.0.4+incompatible // indirect
	github.com/mattermost/logr/v2 v2.0.21 // indirect
	github.com/mattermost/mattermost-plugin-api v0.1.1 // indirect
	github.com/mattermost/mattermost-server/v6 v6.7.2 // indirect

step: run with goland
after this i receive compile error:

expect: compilation without errors from non-write files (files like github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go)

I'm sorry, I don't understand "step: try to compile app with "github.com/mattermost/mattermost-plugin-apps/apps" lib". Please mention clear steps, without any screenshots, how should one reproduce this.

@agnivade
i use goland, because it's comfort for me. All code are written in this ide
go version: 1.22

step 1: write code with using library github.com/mattermost/mattermost-plugin-apps/apps (i write bot-app for mattermost)
step 2: install all dependencies in your go.mod - after go mod tidy you will see in go.mod something like this:

module <your module>

go 1.22

require (
...

	github.com/mattermost/ldap v3.0.4+incompatible // indirect
	github.com/mattermost/logr/v2 v2.0.21 // indirect
	github.com/mattermost/mattermost-plugin-api v0.1.1 // indirect
	github.com/mattermost/mattermost-server/v6 v6.7.2 // indirect
...
)

...

step 3: write all creds/envs/configs in your app to prepare for run
step 4: run your code by run-button in goland
step 5: receive compile error:

go/pkg/mod/github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go:87:11: cannot use generic function logr.Int without instantiation
go/pkg/mod/github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go:96:12: cannot use generic function logr.Uint without instantiation
go/pkg/mod/github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go:105:14: cannot use generic function logr.String without instantiation
go/pkg/mod/github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go:130:12: cannot use generic function logr.Bool without instantiation
go/pkg/mod/github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go:143:13: cannot use generic function logr.Array without instantiation
go/pkg/mod/github.com/mattermost/mattermost-server/[email protected]/shared/mlog/mlog.go:146:11: cannot use generic function logr.Map without instantiation

i expected:
run without compile error from library github.com/mattermost/mattermost-server/v6

[ThePsina]

i found that https://github.com/mattermost/mattermost/blob/v6.7.2 on go1.16 and library that is exported here is on go1.18

[ThePsina]

i used libraries from example

Unfortunately, I still don't understand what you are trying to do. I will leave it to someone else.
