In Grails 4, applications include the Spring Boot Developer Tools dependency. This facilitates the automatic restart of the application when alterations are made to source files. It's important to note that the use of Devtools might introduce challenges related to classloading. To ensure smooth implementation, we recommend a thorough review of the provided documentation.

Unlike its earlier versions, Grails 6 does not include this functionality by default. However, incorporating the subsequent dependency into your project's build.gradle file can reinstate this feature:

developmentOnly("org.springframework.boot:spring-boot-devtools")

Furthermore, with Grails 6.0.1, the option to include the "Spring Boot DevTools" feature is available during the application creation process.

@puneetbehl Facing same challenge in Grails 6. Is there option to achieve hot reloading without restart as was in Grails 3? As our application is monolith and having frequent restarts while changing just few lines code here and there. It would slow down development speed.

spring-boot-devtools is the route for Grails 4, 5 and 6. Grails 7 SNAPSHOTS are currently working with https://github.com/HotswapProjects/HotswapAgent

You also need groovy hotswap:
