Get hands-on training on how to tackle build performance issues with the Gradle build cache.
The Gradle build cache significantly reduces build time by reusing outputs produced by other builds in your organization. In this training, you will learn the basics and best practices to make the most of caching in your build. We’ll discuss the different possible architectures, how they affect build performance, and how Develocity can help you manage, analyze, and troubleshoot the build cache.
3-hour training session followed by 30-minutes Q&A.
Gradle build tool users as well as Develocity users interested in speeding up builds are encouraged to attend the training.
This course assumes a good understanding of the Java language and working knowledge of Gradle. It is recommended to attend the Introduction to Gradle training class. Preferrably, you also attended the Advanced Gradle Fundamentals for Java/JVM training. Consider watching the Maximizing Developer Productivity with Develocity video to get more familiar with Develocity.
After this training the participants will be able to:
- Understand the benefits of using the Gradle build cache
- Use and configure the build cache
- Optimize build logic for maximum cacheability
- Maximize the benefits of the build cache with Develocity
- Performance is key
- Approaches for work avoidance
- Common use cases
