After using BOM to declare dependency version management, the dependency version cannot be obtained in the plugin

dependencies {
    api "io.netty:netty-all"
    api "com.google.protobuf:protobuf-java:3.22.2"
    testImplementation "org.springframework:spring-tx:6.0.8"
    testImplementation "org.springframework.boot:spring-boot-starter-test:${libs.versions.springBoot.get()}"
}

project.afterEvaluate {
    project.configurations.forEach {
        for (final def dependency in it.dependencies) {
            println dependency.group + ":" + dependency.name + ":" + dependency.version
        }
    }
}

io.netty:netty-all:null
com.google.protobuf:protobuf-java:3.22.2
org.projectlombok:lombok:null
org.springframework.boot:spring-boot-configuration-processor:null
org.springframework.boot:spring-boot-autoconfigure-processor:null
com.livk.boot:spring-extension-dependencies:1.0.7
io.grpc:protoc-gen-grpc-java:1.53.0
com.google.protobuf:protoc:3.22.2
org.springframework:spring-tx:6.0.8
org.springframework.boot:spring-boot-starter-test:3.0.6

netty-all comes from the springboot version statement, but this way is unable to get the version, what should I do to get it

You are checking the declared version and this correctly is null as you didn’t declare a version.
You probably need to resolve the configuration and check the resolution result.

Because I used the platform to declare the version, the dependency can be imported correctly, but it cannot be taken out directly, it can only be obtained through incoming.resolutionResult.allDependencies

The following way can indeed solve the problem correctly

Is there a better way?

project.afterEvaluate {
    def dependencyResultMap = new HashMap<String, String>()
    List.of(JavaPlugin.COMPILE_CLASSPATH_CONFIGURATION_NAME, JavaPlugin.TEST_COMPILE_CLASSPATH_CONFIGURATION_NAME).forEach { configurationName ->
        project.configurations.named(configurationName).get().incoming.resolutionResult.allDependencies {
            def result = requested.displayName.split(":")
            if (result.length == 3) {
                dependencyResultMap.put(result[0] + ":" + result[1], result[2])
            }
        }
    }
    project.configurations.forEach { configuration ->
        configuration.dependencies.forEach { dependency ->
            def version = dependency.version
            if (version == null || version.isBlank()) {
                version = dependencyResultMap.get(dependency.group + ":" + dependency.name)
            }
            println dependency.group + ":" + dependency.name + ":" + version
        }
    }
}
