Hi,bro. My gradle version is 6.1.1, and I edit project root build.gradle as below:
`buildscript {
ext{
minSdkVersion = 23
targetSdkVersion = 29

    kotlinVersion = "1.3.72"
}
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:4.0.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"
    classpath 'androidx.navigation:navigation-safe-args-gradle-plugin:2.3.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

}

allprojects {
repositories {
google()
jcenter()
maven { url 'https://www.jitpack.io' }
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

subprojects { prj ->

prj.afterEvaluate {
    tasks.register("depsize") {
        description = 'Prints dependencies for "default" configuration'
        doLast() {
            listConfigurationDependencies(configurations.default)
        }
    }

    tasks.register("depsize-all-configurations") {
        description = 'Prints dependencies for all available configurations'
        doLast() {
            configurations
                    .findAll { it.isCanBeResolved() }
                    .each { listConfigurationDependencies(it) }
        }
    }
}

}

def listConfigurationDependencies(Configuration configuration) {
def formatStr = "%,10.2f"

def size = configuration.collect { it.length() / (1024 * 1024) }.sum()

def out = new StringBuffer()
out << "\nConfiguration name: \"${configuration.name}\"\n"
if (size) {
    out << 'Total dependencies size:'.padRight(65)
    out << "${String.format(formatStr, size)} Mb\n\n"

    configuration.sort { -it.length() }
            .each {
                out << "${it.name}".padRight(65)
                out << "${String.format(formatStr, (it.length() / 1024))} kb\n"
            }
} else {
    out << 'No dependencies found';
}
println(out)

}`
I run "gradle depsize" and get result: No dependencies found

What wrong with my use? Please help me...

@UltramanTIGA did you try running gradle depsize-all-configurations? What's the output?

@medvedev Oh, awesome! It output the list with many configuration name, some of them show "No dependencies found", and some show the dependencies list.
So you mean I should change the configuration name as what I want?

@UltramanTIGA
Yep, you may for example change "depsize" task to use a configuration other than "default".

@medvedev Ok.Thanks a lot!

In case somebody needs the same in .kts

tasks.register("depsize") {
	description = "Prints dependencies for \"default\" configuration"
	doLast {
		listConfigurationDependencies(configurations["default"])
	}
}

tasks.register("depsize-all-configurations") {
	description = "Prints dependencies for all available configurations"
	doLast {
		configurations
				.filter { it.isCanBeResolved }
				.forEach { listConfigurationDependencies(it) }
	}
}

fun listConfigurationDependencies(configuration: Configuration ) {
	val formatStr = "%,10.2f"

	val size = configuration.map { it.length() / (1024.0 * 1024.0) }.sum()

	val out = StringBuffer()
	out.append("\nConfiguration name: \"${configuration.name}\"\n")
	if (size > 0) {
		out.append("Total dependencies size:".padEnd(65))
		out.append("${String.format(formatStr, size)} Mb\n\n")

		configuration.sortedBy { -it.length() }
				.forEach {
					out.append(it.name.padEnd(65))
					out.append("${String.format(formatStr, (it.length() / 1024.0))} kb\n")
				}
	} else {
		out.append("No dependencies found")
	}
	println(out)
}

@phi1ipp thanks :)

Hi, I'm getting this error > Could not get unknown property 'default' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer. when I run ./gradlew depsize.
I'm using gradle 7.2.2 by the way, any help will be much appreciated.
Thanks.

For anyone who is having issues with the configurations.default, you can do the following.

1. Print all your configurations to see what you've got.
2. Replace default with a configuration that you would like to analyze. For example, you can use debugImplementationDependenciesMetadata instead of default.
3. Run ./gradlew depsize

configurations["default"].isCanBeResolved = true

on the top of build.gradle.kts
