pod lib lint failed to validate a Kotlin multiplatform library - kotlin-multiplatform

Question

we are following the KMM documentation to build a very simple library available for our IOS and Android apps.
Following the sample project generated by android studio for a KMM library, we were able to install and intergrate manually the library built, in a IOS project.
Now we are trying to publish this library on cocoapod and make it available for installation.
The lib is called shared.. a shared.podspec is generated..
if we run
pod lib lint shared/shared.podspec --verbose
we have an error
`Testing with xcodebuild.
-> shared (0.3)

Scrolling up to the error I got:

FAILURE: Build failed with an exception.
* What went wrong:
Directory '/' does not contain a Gradle build.
A Gradle build should contain a 'settings.gradle' or 'settings.gradle.kts' file in its root directory. It may also contain a 'build.gradle' or 'build.gradle.kts' file.
To create a new Gradle build in this directory run 'gradlew init'

Any idea?

pod repo push fails
we tried to publish the library manually ignoring the lint , and it installed with no errors but it fails later during the build of the ios project.
kdoctor doesn't give any error. All good.
