SqlDelight Plugin not detected if more than one plugin defined in Gradle dependency classpath

When trying to set up multi-module support where ModuleA depends on ModuleB, if ModuleA also happens to apply another Gradle Plugin, such as the Protobuf Gradle Plugin, then the Gradle configuration will complain that ModelA:

Cannot depend on a module with no sqldelight plugin.

Example:

ModuleA's build.gradle snippet:

buildscript {
    dependencies {
        classpath libs.protobufGradlePlugin <-- Causes Gradle configuration to fail
        classpath libs.sqldelight.gradlePlugin
    }
}

apply from: configs.kotlin.androidLibrary
apply plugin: 'com.squareup.sqldelight'

sqldelight {
    Database {
        packageName = "com.example.coredata.data"
        dependency libs.featureData
    }
}

ModuleB's build.gradle snippet:

buildscript {
    dependencies {
        classpath libs.sqldelight.gradlePlugin
    }
}

apply from: configs.kotlin.androidLibrary
apply plugin: 'com.squareup.sqldelight'

sqldelight {
    Database {
        packageName = "com.example.featuredata.data"
    }
}

If I comment out classpath libs.protobufGradlePlugin, the Gradle configuration succeeds.

I have attached a repro Android project. If you go to coredata/build.gradle, you can uncomment the classpath definition that has been commented out in order to repro the issue. Thank you!

thats super weird. Thanks for the repro project, will take a look at this

the issue here is having all the separate buildscript classpaths, that’s confusing some part of gradle. If I consolidate the classpath into the root build.gradle its fine:

buildscript {
    ...
    dependencies {
        classpath libs.agp
        classpath libs.kotlin.gradlePlugin
        classpath libs.protobufGradlePlugin
        classpath libs.sqldelight.gradlePlugin
    }
}
