Unable to GenerateCustomBeat with Git Bash on Windows

Mint-M · January 22, 2020, 3:05am

I have followed all steps of the official guide bellow to generate a custom beat.
https://www.elastic.co/guide/en/beats/devguide/current/newbeat-generate.html#newbeat-generate

It works on CentOS8 ,however I met a few problems on Windows.

Git 2.25.0 ,Python 2.7.17 ,go 1.13.5 and virtualenv 16.7.9 were installed on this Windows laptop.

I fixed the first problem of the wrong directory format myself by editing beats\generator\common\beatgen\setup\setup.go.

Line 100: "git archive --remote "+beatPath+" HEAD | tar -x --exclude=x-pack -C "+vendorPath) should be replaced with "git archive --remote '"+beatPath+"' HEAD | tar -x --exclude=x-pack -C "+vendorPath).

$ mage GenerateCustomBeat

Error: error running git archive: running "sh -c git archive --remote D:\go\src\github.com\elastic\beats HEAD | tar -x --exclude=x-pack -C vendor\github.com\elastic\beats" failed with exit code 2

Nevertheless, it caused some loops after running 'mage GenerateCustomBeat' again.
The output kept showing "Found Elastic Beats dir at C:\Users\beats\go\src\github.com\your-github-name\examplebeat\vendor\github.com\elastic\beats".
Unfortunately, I didn't find any useful message which could help resolve this problem.
It can also be reproduced on a fresh installed Windows computer.

Hey @Mint-M, welcome to discuss

 remote: fatal: 'D:gosrcgithub.comelasticbeats' does not appear to be a git repository

This looks like a string where the backslashes are not being correctly escaped, it actually looks like a bug. Could you please open a new issue?

Thanks!

Hi @jsoriano, we encountered the exact same issue.
Is there a bug opened?
In addition, is there a known work around we could use?

Mint-M · February 24, 2020, 11:23am

Thanks for your reply.
It can be fixed by editting 'beats\generator\common\beatgen\setup\setup.go' as I mentioned above. However,I was stucked at ' "Found Elastic Beats dir at C:\Users\beats\go\src[github.com](http://github.com/)\your-github-name\examplebeat\vendor[github.com](http://github.com/)\elastic\beats"' which kept showing after that fix.
The documentation of beats doesn't mention whether it is officially supported to generate custom beats on Beats and I haven't seen successful examples of generating beats on windows.
Is it possible for you to confirm if it can be reproduced by the elastic team and generating beats on windows will be supported?
