Setting up a Gradle project with subprojects involves a thoughtful configuration to ensure a smooth development process. In this article, we’ll walk through the step-by-step process of configuring a Gradle project to incorporate essential tools and plugins such as Spotless, Javadoc, Dependency Check, License Info, SonarLint, JaCoCo, and Test Reporting. Each section includes complete configuration examples, making it easier for developers to implement these features in their own projects.

1. Spotless – Code Formatting:

Spotless ensures consistent code formatting across a project. Add the following configuration to your build.gradle:

plugins {
    id 'com.diffplug.spotless' version '6.20.0'

spotless {
    java {
        // Add any additional formatting rules as needed

2. Javadoc Generation:

Generate Javadoc for your project with the following configuration:

plugins {
    id 'java'

tasks.register('javadoc') {

    doLast {
        javadoc {
            sourceSets = sourceSets.main
            classpath = configurations.compile
            destinationDir = file("$buildDir/docs/javadoc")
            // Add any additional Javadoc options as needed

3. Dependency Check:

Use the OWASP Dependency Check plugin to analyze dependencies for vulnerabilities:

plugins {
    id 'org.owasp.dependencycheck' version '<owaspVersion>'

dependencyCheck {
    analyzers.assemblyEnabled = false
    suppressionFile = file('./config/owasp_suppression.xml')

4. License Info:

Generate license information for your project:

plugins {
    id 'se.solrike.otsswinfo' version '<solrikeOTSswInfoVersion>'

otsSwInfo {
    extraVersionInfo = [
        "SBOM for $ $project.version",
        "ID: $$$project.version",
        "Timestamp: ${new Date()}"

5. SonarLint Integration:

Configure SonarLint to ensure code quality:

plugins {
    id 'se.solrike.sonarlint' version '<solrikeSonarlintVersion>'

sonarlintMain {
    reports {
        text.enabled = false
        html.enabled = true
        xml.enabled = true
        sarif.enabled = false
    exclude "build/generated/**"
    // Add any additional SonarLint configurations as needed

6. JaCoCo – Code Coverage:

Generate code coverage reports using JaCoCo:

plugins {
    id 'jacoco'

jacoco {
    toolVersion = '<jacocoVersion>'

test {

tasks.register("jacocoTestReport", JacocoReport) {

    reports {
        xml.required = true
        html.required = true

7. Test Reporting:

Consolidate test reports from subprojects:

tasks.register('testReport', TestReport) {
    destinationDir = file("$buildDir/reports/allTests")

    reportOn subprojects*.test


By incorporating these configurations into your Gradle project, you ensure code quality, maintainability, and a streamlined development process. These plugins and tools work seamlessly together to provide a comprehensive development environment. Feel free to customize these configurations based on your project’s specific needs and requirements.
