Push rejected, failed to compile Go app.

go.mod

module repo_name

go 1.15

require (
	github.com/gorilla/mux v1.8.0
	github.com/joho/godotenv v1.3.0
	go.mongodb.org/mongo-driver v1.4.6
)

Could you say me why it doesn't work? Dockerfile, heroku.yml, Makefile and Procfile were copied from https://github.com/heroku/go-getting-started

Thanks for the report.

The getting started app could use an update. I do notice that in the go.mod you shared, there's a go 1.15 line but no corresponding // +heroku goVersion go1.15 line. This means the buildpack will use the default version, which is still 1.12.

Would you be up for trying to add the goVersion line? Something like:

// +heroku goVersion go1.15

module repo_name

go 1.15

require (
	github.com/gorilla/mux v1.8.0
	github.com/joho/godotenv v1.3.0
	go.mongodb.org/mongo-driver v1.4.6
)

The buildpack should not hide the error here, that is something to be improved.

@danp
I did, but it still doesn't want to install it. I tried without getting started app template, just using go mod, but it still doesn't want to deploy. I asked a question on StackOverflow, so let me copy it here:

I tried to deploy a Go app from monorepo with the help of go mod, but it didn't help. Then, I moved subtree to another repo, but even here it shows me the same error. It seems to me that it cannot find packages, but when I clone and run the repo, it runs. The error:

-----> Building on the Heroku-20 stack
-----> Go app detected
-----> Fetching jq... done
-----> Fetching stdlib.sh.v8... done
-----> 
       Detected go modules via go.mod

go.mod:

module repo_name

go 1.15

require (
	github.com/gorilla/mux v1.8.0
	github.com/joho/godotenv v1.3.0
	go.mongodb.org/mongo-driver v1.4.6
)

The steps, that I took:

Move server code to monorepo/backend dir
Run go mod init
Run go mod vendor
Push it to git repo
Push the subtree of prefix backend to Heroku remote
Heroku rejects the push

Thanks. Checking: did you try adding // +heroku goVersion go1.15 to your go.mod? The most recent example you gave did not include it.

Could you also please clarify what you mean by:

Push the subtree of prefix backend to Heroku remote

The git commands you're running would be helpful.

Thanks!

@danp Let me explain briefly.
I have a monorepo with the following structure:

monorepo
└──backend
	├── README.md
	├── go.mod
	├── go.sum
	├── main.go
	├── mongoConnector
	│   └── db.go
	└── vendor
		├── github.com
		├── go.mongodb.org
		├── golang.org
		└── modules.txt

I need to deploy it to Heroku, but then I faced some issues with deploying a monorepo to Heroku. So I pushed backend folder
to another repo using git subtree push --prefix backend remote main --squash and from here I tried to deploy it via Heroku's deploy, but it shows me this:

-----> Building on the Heroku-20 stack
-----> Go app detected
-----> Fetching jq... done
-----> Fetching stdlib.sh.v8... done

Thanks. And I realize now that you are getting go1.15.8 based on the build output.

And double checking: if you run go mod vendor again in the backend directory, does vendor/modules.txt change?

I was able to take https://github.com/heroku/go-getting-started, follow these steps, and then do a successful push:

clone https://github.com/heroku/go-getting-started somewhere and cd into it
mkdir backend
git mv Procfile go* main.go static templates vendor backend
cd backend
replace go 1.12 in go.mod with go 1.15
add // +heroku goVersion go1.15 to go.mod
run go mod vendor
commit results
git subtree push --prefix backend heroku main --squash

@danp do I need to have static folder?

@danp now it shows this:

I am sorry, but could you investigate my repo? I think, I'm doing something wrong. Thank you!

Dan Peterson · Answer 8 · Mon Feb 22 2021 23:47:33 GMT+0800 (China Standard Time)

In go.mod, can you please try changing this:

// +heroku goVersion go 1.15

to this:

// +heroku goVersion go1.15

(note space removed between go and 1.15)

Adil Akhmetov · Answer 9 · Wed Feb 24 2021 00:45:13 GMT+0800 (China Standard Time)

@danp I don't know whether it may be a solution, but I finally deployed it via godep. Followed instructions from the official docs https://devcenter.heroku.com/articles/go-dependencies-via-godep

Adil Akhmetov · Answer 10 · Sat Feb 27 2021 21:49:27 GMT+0800 (China Standard Time)

In go.mod, can you please try changing this:
// +heroku goVersion go 1.15
to this:
// +heroku goVersion go1.15
(note space removed between go and 1.15)

It worked!
