Writing Plugins for Gradle - ONLINE Course
There are few people in the world more knowledgeable about writing Gradle Plugins than @ysb33r. With several books published around the topic. I am sure the course will be good because I attended a workshop he taught at Greach about the same topic and it was one of the highlights of the conference for me.
Organize your calendar and learn Gradle Plugin development. I will do the same.
Course objectives:
- Write declarative DSLs to aid comprehensibility for build script authors
- Work with external tools and cache them without the need for installation.
- Craft plugins that are compatible with both Groovy & Kotlin DSLs.
- Use of lazy evaluation for maximum flexibility.
- Using configuration for internal and external usage.
- Multi-layer extensions for maximum task flexibility.
- Testing plugins for functionality and compatibility.
- Caching dependencies for testing.
- Publishing plugins for use and discoverability.
- Extending DevOps automation pipeline through Gradle plugin functionality
