Everytime i do any changes to java code, it won't reflect after i saves the file

Question

I am using Eclipse Neon for my java project, every time I do any changes to java code, it won't reflect after I save the file (for ex: a simple syso statement). I have to do maven clean and maven install my project then restarts the boot.

Eclipse Neon is 11 releases behind. Do not waste time by using outdated software. Please tell the command line used to run it (in the run configuration there is a button _Show Command Line_ to get the command line). — howlger, Oct 20 '20 at 06:20

Add devtools dependency to your project in pom.xml (if spring boot project) :-

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-devtools</artifactId>
</dependency>

And enable Build Automatically in eclipse :-

Ensure that Build Automatically option in Project->Build Automatically, is enabled.

Also try to update the project using Mvn > update project
