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
2020/01/22 10:10:04 Found Elastic Beats dir at D:\go\src\github.com\elastic\beats
Enter the beat name [examplebeat]:
Enter your github name [your-github-name]:
Enter the beat path [github.com/your-github-name/examplebeat]:
Enter your full name [Firstname Lastname]:
Enter the beat type [beat]:
fatal: sent error to the client: git upload-archive: archiver died with error
remote: fatal: 'D:gosrcgithub.comelasticbeats' does not appear to be a git repository
remote: git upload-archive: archiver died with error
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
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.
