Publishing SNAPSHOT versions of Android libraries using Android Gradle Plugin 7+ - android-gradle-plugin

Question

I have an Android library (gradle multi module project) where I publish to two different Nexus Maven2 repositories with strict versioning, a release repository and a snapshot repository.
This has worked well using Android Gradle Plugin 4.0.1.
command:
gradlew -PmavenRepoUrl=https://myserver.com/nexus/repository/project-snapshots -PmavenRepoCredentialType=PasswordType -PmavenUser=$NEXUS_USER -PmavenPassword=$NEXUS_PASSWORD publishDebugPublicationToMavenRepository
build.gradle.kts:
plugins {
id("com.android.library")
id("maven-publish")
...
}
val mavenRepoUrl: String by project
val mavenRepoCredentialType: String by project
val mavenPublicAccessKey: String by project
val mavenPublicSecretKey: String by project
val mavenUser: String by project
val mavenPassword: String by project
afterEvaluate {
publishing {
repositories {
maven(url = mavenRepoUrl) {
when (mavenRepoCredentialType) {
"AwsCredentialType" -> {
credentials(AwsCredentials::class) {
accessKey = mavenPublicAccessKey
secretKey = mavenPublicSecretKey
}
}
"PasswordType" -> {
credentials(PasswordCredentials::class) {
username = mavenUser
password = mavenPassword
}
}
else -> {
logger.log(ERROR, "Unsupported credential type: $mavenRepoCredentialType")
}
}
}
}
publications {
create<MavenPublication>("Release") {
from(components.getByName("release"))
groupId = project.group as String
artifactId = "my-android-project-${project.name}"
version = project.version as String
}
create<MavenPublication>("Debug") {
from(components.getByName("debug"))
groupId = project.group as String
artifactId = "my-android-project-${project.name}"
version = project.version as String
}
}
}
}
But after updating to Android Gradle Plugin 7.0+ I'm getting this error:
Execution failed for task ':core:publishDebugPublicationToMavenRepository'.
> Failed to publish publication 'Debug' to repository 'maven'
> Could not PUT 'https://myserver.com/nexus/repository/project-snapshots/com/myproject/1.1.0-M25/my-project-1.1.0-M25.aar'. Received status code 400 from server: Repository version policy: SNAPSHOT does not allow version: 1.1.0-M25
(When upgrading Android Gradle Plugin I had to remove the "isDebuggable" attribute from the build variants. Maybe that's a clue?).
To troubleshoot I tried explicitly setting the version to "-SNAPSHOT" for debug builds, build.gradle.kts:
publications {
create<MavenPublication>("Debug") {
...
version = (project.version as String) + "-SNAPSHOT"
...
}
}
but then I get this error:
* What went wrong:
Could not determine the dependencies of task ':my-module-2:publishDebugPublicationToMavenRepository'.
> Publishing is not able to resolve a dependency on a project with multiple publications that have different coordinates.
Found the following publications in project ':my-modulue':
- Maven publication 'Release' with coordinates com.myproject:my-module:1.1.0-M25
- Maven publication 'Debug' with coordinates com.myproject:my-module:1.1.0-M25-SNAPSHOT

My setup:
Multi module project with Android library modules
Android Gradle Plugin 7.0.1
Gradle 7.0.2, 7.1.1, 7.2 (doesn't work with any of them)
Kotlin Gradle DSL
Is this a regression caused by the Android Gradle Plugin or is there a way to solve my problem?
