[SOLVED] mavenBom from spring dependency-management Gradle plugin does not add bom to gradle module file

mavenBom from spring dependency-management Gradle plugin does not add bom to gradle module file

I have a simple library project A and I use spring dependency management.

dependencyManagement {
        imports {
            mavenBom("io.grpc:grpc-bom:$grpcBomVersion")
            mavenBom("com.google.protobuf:protobuf-bom:$protobufBomVersion")
        }
    }

Generated pom file fot this project is ok, but generated gradle 'module' file, which is used by default if I import my project A into project B does not contain following code snippet:

"dependencies": [
        {
          "group": "io.grpc",
          "module": "grpc-bom",
          "version": {
            "requires": "1.58.0"
          },
          "attributes": {
            "org.gradle.category": "platform"
          },
          "endorseStrictVersions": true
        },
        {
          "group": "com.google.protobuf",
          "module": "protobuf-bom",
          "version": {
            "requires": "3.24.0"
          },
          "attributes": {
            "org.gradle.category": "platform"
          },
          "endorseStrictVersions": true
        },

This behavior causes that** I need to manually add boms to project B**(project B imports library project A): implementation(platform("io.grpc:grpc-bom:$grpcBomVersion")) implementation(platform("com.google.protobuf:protobuf-bom:$protobufBomVersion"))

if I use platform for library project A:

implementation(platform("io.grpc:grpc-bom:$grpcBomVersion"))
implementation(platform("com.google.protobuf:protobuf-bom:$protobufBomVersion"))

then all is ok, generated gradle .module file contains mentioned lines:

"dependencies": [
        {
          "group": "io.grpc",
          "module": "grpc-bom",
          "version": {
            "requires": "1.58.0"
          },
          "attributes": {
            "org.gradle.category": "platform"
          },
          "endorseStrictVersions": true
        },
        {
          "group": "com.google.protobuf",
          "module": "protobuf-bom",
          "version": {
            "requires": "3.24.0"
          },
          "attributes": {
            "org.gradle.category": "platform"
          },
          "endorseStrictVersions": true
        },

So no need to manually import boms to project B(project B imports library project A): implementation(platform("io.grpc:grpc-bom:$grpcBomVersion")) implementation(platform("com.google.protobuf:protobuf-bom:$protobufBomVersion"))

But I don't like to use platform gradle notation in project A, cause in this case I have different versions of same transitive dependencies in project A. I don't want to exclude them manually. When I use dependency-management plugin in project A - I see that my duplicates of transitive dependencies are gone , so prefer to use dependency-management plugin instead of platform, but it causes missed boms in generated gradle .module file
