Dependencies overview generator plugin

Gradle plugin which gathers project dependencies and exports them in Markdown/JSON format.

Installation

Apply the plugin in your build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.vgaidarji:dependencies-overview:<VERSION>'
    }
}

apply plugin: 'dependencies.overview'

Configuration

Full list of available configuration properties can be found in DependenciesOverviewExtension.

dependenciesOverview {
    output.json = true
    output.markdown = true
    output.folder = "build/reports/dependencies" // by default `= null` (project root)
}

Once everything configured, you can generate dependencies overview report by executing appropriate Gradle task:

./gradlew dependenciesOverview

Sample reports

You can find sample reports in repository root:

• DEPENDENCIES-OVERVIEW.md
• DEPENDENCIES-OVERVIEW.json

JSON

{
    "dependencies": [
        {
            "group": "com.android.support",
            "version": "25.3.1",
            "name": "animated-vector-drawable",
            "module": {
                "group": "com.android.support",
                "name": "animated-vector-drawable"
            }
        },
        {
            "group": "com.android.support",
            "version": "25.3.1",
            "name": "appcompat-v7",
            "module": {
                "group": "com.android.support",
                "name": "appcompat-v7"
            }
        },
        {
            "group": "joda-time",
            "version": "2.3",
            "name": "joda-time",
            "module": {
                "group": "joda-time",
                "name": "joda-time"
            }
        },
        {
            "group": "org.slf4j",
            "version": "1.7.7",
            "name": "slf4j-android",
            "module": {
                "group": "org.slf4j",
                "name": "slf4j-android"
            }
        }
    ]
}

Markdown

Group	Name	Version
com.android.support	animated-vector-drawable	25.3.1
com.android.support	appcompat-v7	25.3.1
joda-time	joda-time	2.3
org.slf4j	slf4j-android	1.7.7

Execution time

On a sample Android project with ~40 compile time dependencies JSON & Markdown reports generation takes up to ~70 milliseconds, which is very insignificant.

Development

This project is written mainly in Kotlin and uses ktlint linter.

build-install.sh and build-install-run.sh scripts can be used during local development. They contain sequence of Gradle commands which help building/installing/running plugin.

• build-install.sh builds the plugin and installs it into local repository (repo folder in project root)
• build-install-run.sh uses build-install.sh + runs plugin on sample projects.

How to release

Plugin is published to and Maven Central repository (Gradle guide). maven-publishing.gradle contains necessary configurations.
We need to specify few mandatory properties in global ~/.gradle/gradle.properties file:

signing.keyId=
signing.password=
signing.secretKeyRingFile=

SONATYPE_USERNAME=
SONATYPE_PASSWORD=

Follow Signatory credentials for more details.

As per https://circleci.com/blog/publishing-java-android-libraries/, following environment variables should be added to Circle CI project environment variables:

• ORG_GRADLE_PROJECT_SONATYPE_USERNAME
• ORG_GRADLE_PROJECT_SONATYPE_PASSWORD

publishToMavenLocal task can be used to perform a dry run publishing to local maven repository.

For automatic publishing from Sonatype Nexus staging repository to release https://github.com/gradle-nexus/publish-plugin/ plugin is used. ./gradlew clean build publishToSonatype closeAndReleaseSonatypeStagingRepository command is used to upload signed plugin artifact to Maven Central. Publishing may take some time, check https://oss.sonatype.org for newly published version.

TODO

• Add more sample integrations projects (Java application, project with modules)
• Divide dependencies into groups by project module
• Introduce task parameter should_print_to_console
• Support other project configurations (currently compile configuration is analysed)
