completion does not work for gradle scripts using kotlin

[abendt]

given

• gradle flie build.gradle.kts and
• an empty settings.gradle.kts

with this configuration the completion does not detect the build file and does not show the tasks.

it works when i rename settings.gradle.kts to settings.gradle and add an entry rootProject.buildFileName = "build.gradle.kts"

it would be nice if the completion logic also would detect the buildfile without that

This commit seems to have broken completion in bash. I'll see if I can pin down where it goes wrong.
