Hi there @panekj I don't have access to your repo to test against. Are you still running into this issue?

If so, can you please provide access to the plugin so that we can test against it to see what might be happening. Thanks.

I had a similar issue.
packer-sdc which was working fine, had stopped working and got stuck every time I did make generate within my plugin template.

I have a packer plugin for UTM and I am adding new builders/post-processors, generating hcl2spec for my new configs depends on proper working of packer-sdc.

packer-plugin-utm %packer-sdc   
^C^Z^D

I was not able to get any trace to report specific error, I can reproduce it in my machine outside of my plugin .
I even tried older release , but same result.

~ %go install github.com/hashicorp/packer-plugin-sdk/cmd/packer-sdc@v0.5.3
go: downloading github.com/hashicorp/packer-plugin-sdk v0.5.3
go: downloading golang.org/x/crypto v0.17.0
~ %packer-sdc --version               
zsh: killed     packer-sdc --version

(this did not happen inside a fresh VM, only in my machine which was working fine before)

I had to continue with the development of my plugin, so I forced it to use the main branch

github.com/hashicorp/packer-plugin-sdk v0.5.5-0.20241218223252-db2a445bf726

Now it is working.
Because nature of the issue (binary gets stuck with no output) I do not have any idea what caused it.
