Allow user to use higher version of tkn with warning.

[sudhirverma]

If the user has a newer version of tkn cli available, and do not want to download an older version from extension then show the warning message that the user has a newer version and extension may not work 100% correctly.

A warning should suffice, without blocking the extension to issue tkn comments with the whatever tkn version that is installed on user's workstation.

Is it possible to display this warning when a tkn command does not work as expected, rather than upfront?

[sudhirverma]

@siamaksade we will show the warning message upfront of the extension. while running tkn command in case of failure/command doesn't work as accepted we will show the same message as provided by tkn command.

I think we can show warning when we detect version of tkn if installed cli has bigger version, there:

vscode-tekton/src/tools.ts

Line 123 in 4ee4752

public static async selectTool(locations: string[], versionRange: string): Promise<string> {

while running tkn command in case of failure/command doesn't work as accepted we will show the same message as provided by tkn command.

It is a good idea.
