GenerateCustomBeat returns error for missing github.com/elastic/beats/v7

andrew-expanse · March 16, 2020, 3:16pm

Hi all,

I'm attempting to create a new custom beat but am hitting some errors when using the mage GenerateCustomBeat command.

Error: error while getting required beats version: running "go get -d -u github.com/elastic/beats/v7@master" failed with exit code 1

I did some searching but haven't seen any relevant topics yet. My dev environment is fresh after following these guidelines (https://www.elastic.co/guide/en/beats/devguide/current/beats-contributing.html#setting-up-dev-environment).

It seems like go is trying to fetch a too old version of master branch. We need to adjust the default value to make sure Go is not attempting to fetch an incorrect version. Do you mind opening an issue on GH?

You can work around the issue by providing the last commit from master.

andrew-expanse · March 17, 2020, 2:49pm

Created https://github.com/elastic/beats/issues/17033

When you say I could work around this by providing the last commit from master, do you mean I should enter a commit hash/id when asked Enter the github.com/elastic/beats revision?

kvch · March 17, 2020, 6:49pm

Exactly. Sorry for not being clear.

andrew-expanse · March 18, 2020, 4:23pm

This could totally be user error - but I'm still seeing a very similar error when providing the last commit hash.

Probably not, a few parts of the generators are not working at the moment since we adapted go modules. Let me look into it.

kvch · March 18, 2020, 4:50pm

What is your go version?

andrew-expanse · March 18, 2020, 4:50pm

go1.14 darwin/amd64

kvch · March 18, 2020, 5:00pm

The current supported Go version for beats is 1.13.8 as you can see in .go-version. Please use that to generate your new Beat. Also, that migth be broken as well. I am fixing that now.

The adoption of go 1.14 is tracked in this issue: https://github.com/elastic/beats/issues/16566

andrew-expanse · March 18, 2020, 5:33pm

Thanks so much @kvch !

For anyone else who runs into this, if you used brew to install go here's a handy guide for downgrading. https://blog.notmyhostna.me/downgrade-go-installed-with-homebrew/

Johann_Tanzer · March 26, 2020, 8:55am

I have been trying for hours to get this to work and it is frustrating.

go version:

$ go version
go version go1.13.8 linux/amd64

when i try to generate with the last commit from master as revision, as mentioned above:

Did you get this to work @andrew-expanse ???

Mike_Ware · March 29, 2020, 5:28pm

This is also effecting x-pack module builds.
mage
Error determining list of magefiles: failed to list non-mage gofiles: exit status 1: go: inconsistent vendoring in /root/go/src/github.com/elastic/beats:
go.mod requires github.com/elastic/beats/v7 but vendor/modules.txt does not include it.
run 'go mod tidy; go mod vendor' to sync

running provided go sync and tidy does not fix it as there is no v7 module available.

andrew-expanse · March 29, 2020, 6:31pm

I did manage to get it to work after some trial and error, but I've since restarted my machine and lost the command that actually worked - I believe I was just doing what you were doing here though.

Mike_Ware · March 30, 2020, 4:23pm

This is what I'm getting when trying to get the module code. Keep in mind I can build filebeat but not the x-pack modules:

whatgeorgemade · April 15, 2020, 9:00pm

I managed to get it working by using a previous commit SHA. When asked for the revision of beats to use, don't just hit enter; paste in the SHA of the commit previous to the most recent in master, which is currently 52fa26598cef8a90c8981970414c780e4fd31dbf.

You might also have to downgrade to Go 1.13.8.

nabeel_ahmed · April 16, 2020, 6:55am

@ whatgeorgemade Downgrading works for me.

whatgeorgemade · April 16, 2020, 10:06pm

Can you explain what the v7 part of the repository is? I can't find a branch or tag with that name but see it everywhere in the code. Why was this added?

I'm working on a PR that is based on a branch from master but now can't use it in a beat because it pulls beats/v7 into the vendors folder.

EDIT: After reading up on Go modules I figured out that adding a replace to go.mod would suffice. After doing that and running mage vendorUpdate, I can test my branch.

kvch · April 20, 2020, 8:53am

Go modules require us to add the major version to the import path:

By definition, a new major version of a package is not backwards compatible with the previous version. This means a new major version of a module must have a different module path than the previous version. Starting with v2 , the major version must appear at the end of the module path (declared in the module statement in the go.mod file). For example, when the authors of the module github.com/googleapis/gax-go developed v2 , they used the new module path github.com/googleapis/gax-go/v2 . Users who wanted to use v2 had to change their package imports and module requirements to github.com/googleapis/gax-go/v2 .

Ref: Go Modules: v2 and Beyond - The Go Programming Language

Szanik · May 5, 2020, 10:19am

Is there a better fix outhere?

I have the same problem.
Ttried to downgrade my go version to 1.13.8
and tried the commit that "whatgeorgemade" mentioned.
And then again with the master.

nothing worked.
It got suck on some the go: finding
e.g.
go: finding github.com/josephspurrier/goversioninfo latest

The problem is also that, at this point of writing, there are 541 Powershell process because of
that.
