FormKiQ Gradle convention plugin

Reusable Gradle convention plugin for FormKiQ Java projects.

Plugin ID: com.formkiq.gradle.java-base

Build with JDK 25 and the included Gradle 9.8.2 wrapper (./gradlew). Projects applying this plugin require JDK 25 and Gradle 9.1.0 or newer.

Features:

• Configurable Java toolchain (defaults to 25)
• Spotless (Java formatting + local whitespace checks for Gradle files)
• SpotBugs (HTML reports, shared exclude filter)
• Checkstyle (10.12.4, project-relative config)
• Gradle Versions plugin
• OWASP Dependency Check conventions
• GraalVM Native plugin (FormKiQ)
• Repositories: mavenLocal, mavenCentral, Sonatype snapshots (optional)

Gradle files use local checks for two-space tab expansion, trailing whitespace, and a final newline. They do not use Groovy-Eclipse or contact Eclipse update sites. Full Groovy indentation and wrapping are no longer enforced. Java and XML formatting are unchanged.

Quick start

Set the JVM version

Set jvmVersion in your project's gradle.properties to choose the Java toolchain used for compilation and tests in the root project and all subprojects:

jvmVersion=21

You can also override it for a single build:

./gradlew build -PjvmVersion=21

The default is Java 25. This setting selects the project toolchain; running Gradle and loading this plugin still require JDK 25.

Apply Gradle plugin

Groovy

Using the plugins DSL:

plugins {
    id 'com.formkiq.gradle.java-base' version '1.0.3'
}

Using legacy plugin application:

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "com.formkiq.gradle:java-base:1.0.3"
  }
}

apply plugin: "com.formkiq.gradle.java-base"

Kotlin

Using the plugins DSL:

plugins {
    id("com.formkiq.gradle.java-base") version "1.0.3"
}

Using legacy plugin application:

buildscript {
  repositories {
    maven {
      url = uri("https://plugins.gradle.org/m2/")
    }
  }
  dependencies {
    classpath("com.formkiq.gradle:java-base:1.0.3")
  }
}

apply(plugin = "com.formkiq.gradle.java-base")
