Convention Plugins & Build Logic
Develop and apply convention plugins to enforce consistent build configurations and standards across your organization.
What are Convention Plugins?
In large Gradle multi-project builds, maintaining consistent configurations across many subprojects can become a challenge. This is where Convention Plugins come in handy.
A convention plugin is essentially a way to package and reuse common build logic and configurations specific to your organization or project. They help enforce standards and reduce boilerplate.
The Problem: Inconsistent Build Logic
Imagine you have several Java subprojects. Each needs to apply the java-library plugin, set a specific Java toolchain, and configure common repositories. Without convention plugins, you might end up with repetitive and slightly different configurations in each build.gradle file.
/* project-a/build.gradle */
plugins {
id 'java-library'
}
java {
toolchain {
languageVersion = JavaLanguageVersion.of(17)
}
}
repositories {
mavenCentral()
}
/* project-b/build.gradle */
plugins {
id 'java-library'
}
java {
toolchain {
languageVersion = JavaLanguageVersion.of(17)
}
}
repositories {
mavenCentral()
