It seems that this line

ide/scripts/src/main/resources/scripts/command/dotnet

Line 35 in 249f5f6

doRun new -i devon4net.WebApi.Template

leads to an error in github actions runners. At the moment, I can't figure out why another installation of dotnet is started after the installation of dotnet. And why git commands are not found?

I suppose that the github hosts don't the typical directory structure.

ide/scripts/src/main/resources/scripts/command/dotnet

Line 35 in 249f5f6

doRun new -i devon4net.WebApi.Template

This command creates a .templateengine file under .../User/.templateengine. Maybe that is the reason why the installation leads to this kind of error.

I have noticed that after running doRun in line 33, doSetup is run again in line 40. This leads to an error which is described in this issue.

ide/scripts/src/main/resources/scripts/command/dotnet

Lines 29 to 44 in 249f5f6

	function doSetup() {
	doInstall "dotnet" "${DOTNET_VERSION}" "${1}"
	if doExists ~/.templateengine/packages/Devon4Net.WebAPI.Template*
	then
	doDebug "Devon4net template already installed."
	else
	doRun new -i devon4net.WebApi.Template
	fi
	}
	function doRun() {
	doSetup silent
	doEcho "Running: dotnet ${*}"
	if doIsQuiet
	then
	"${DOTNET}" "${@}" > /dev/null

Why did this happened? Should not doInstall skip the installation if the tool is already installed. Or does this error happen because doInstall and doRun are run in same session?

[alfeilex]

I was able to fix this error by replacing line 35 with
doRunCommand "'${DOTNET}' new -i devon4net.WebApi.Template"

But does this also happen in other commandlets?
