Have you tested it with bare g8? I'm asking just to understand if it is sbt or g8 related

No, only with sbt

[TonioGela]

Okay, can you test it with the g8 version of this branch?
The first comment should contain the instructions to build it locally, but I can help you out if you need it. It should fix authentication errors by simply reading the .ssh/conf file and using it to pick the correct ssh key.

[TonioGela]

Just in case, the instructions are these:

checkout repo and publish local dependency

git clone https://github.com/TonioGela/giter8.git
cd giter8
git checkout SSH_FIX
sbt publishLocal

install Coursier

curl -fLo cs https://git.io/coursier-cli-"$(uname | tr LD ld)"
chmod +x cs
./cs install cs
rm cs

or install Coursier on Windows (using cmd.exe, not PowerShell)

bitsadmin /transfer cs-cli https://git.io/coursier-cli-windows-exe "%cd%\cs.exe"
.\cs --help

and then install locally the fixed version of giter8

cs bootstrap org.foundweekends.giter8:giter8-launcher_2.12:0.13.1-SNAPSHOT --main giter8.LauncherMain -f -o <custom-g8-path>

then you can run the custom version of g8 using the executable that you find at <custom-g8-path> like ./<custom-g8-path> or .\<custom-g8-path>.exe if you are on windows.

I hope that ./<custom-g8-path> ssh://[email protected]:7999/performance/gatling-template.g8.git won't cause the private key error

@chepk version 0.14.0 should have solved the issue. Can you check?

[chepk]

Sorry, I missed your comments. Asked colleagues to check
