[ilovejs]

How to reproduce

mockery version: v2.10.0
env: go 1.18
demo repo: https://github.com/sgreben/testing-with-gomock

Other bugs

in a larger private repo, internal error
2022/03/16 10:50:38 internal error: package "net/http" without types was imported from "xxx"

Possible reason

when downgrade to go1.16.15 it works for my larger scale project but failed on that demo repo up there
so it's a positive feedback

Having the same issue with 1.18 internal error: package "fmt" without types was imported from ...

Having similar issue with the error message
invalid operation: ctx.Value(some_key) (value with invalid type) is not an interface" dry-run=false version=v2.9.4

update to mockery version: v2.10.0 is ok

Having a similar issue with Go 1.18: Unexpected package creation during export data loading

Adding packages.NeedDeps flag to packages config in parse.go fixes the problem. Similar fix has been applied to gqlgen (see 99designs/gqlgen#1961).

Has similar issue with system version overriding user version of mockery

which mockery
/usr/local/bin/mockery

rm /usr/local/bin/mockery

go install github.com/vektra/mockery/v2@latest

which mockery
/Users/{username}/go/bin/mockery

mockery worked again after running this

This is a bit confusing... The binary downloaded from https://github.com/vektra/mockery/releases/tag/v2.10.0 (darwin_arm64) reports an error:

➜  ~/Downloads/mockery_2.10.0_Darwin_arm64/mockery --name Client
23 Mar 22 09:35 CET INF Starting mockery dry-run=false version=v2.10.0

2022/03/23 09:35:59 internal error: package "net/http" without types was imported from "<snip>"

But running go install manually works:

➜ go install github.com/vektra/mockery/v2@v2.10.0

➜ $GOBIN/mockery --name Client
23 Mar 22 09:37 CET INF Starting mockery dry-run=false version=v2.10.0

23 Mar 22 09:37 CET INF Generating mock dry-run=false interface=Client qualified-name=<snip> version=v2.10.0

Both report the same version, was the release built from the wrong tag?

[atombender]

The release is presumably built with Go 1.17, while go install builds it using your local Go 1.18.

Sadly 1.10.1 does not fix this issue. The release 2.10.1 seems to be built with go 1.16.14:

➜ go version -m ~/Downloads/mockery_2.10.1_Darwin_arm64/mockery
/Users/claus/Downloads/mockery_2.10.1_Darwin_arm64/mockery: go1.16.14
...

Running mockery in a folder with this simple test file does not work:

package tmp
import "sync"
func stuff() {
	var m sync.Map
	m.Range(func(key interface{}, value interface{}) bool {
		return false
	})
}

While running a version manually built with go1.18 works:

➜ go version -m ../mockery
../mockery: go1.18
