How to compile only changed file using gradle build in java projects

Question

I am using gradle to build a java project.

I see that whenever there is a change in one java file entire projects gets rebuilt. Is there a way to compile only affected java files instead of all the files.

Gradle now supports compile avoidance, and has support for incremental compilation since earlier. You do not have to do anything to enjoy these features. Just update Gradle. See https://blog.gradle.org/incremental-compiler-avoidance
