Intellij IDEA Java classes not auto compiling on save
To switch on auto-compilation in IntelliJ IDEA, launch Settings (Ctrl+Alt+S), select Compiler under the Build, Execution, Deployment tab. Tick the box for "Build project automatically". If you wish this feature to operate even when IntelliJ is running in the background, activate the Registry using Ctrl+Shift+A, type Registry..., and check compiler.automake.allow.when.app.running.
Turn off Power Save Mode to enable auto-compilation by hitting Ctrl+Shift+A, typing Power Save Mode, and ensuring it's deactivated.
In pre-2021.2 versions of IntelliJ IDEA, also enable 'Allow auto-make to start even if the dev app is running' for background compilation. Go retro with older IntelliJ (pre-12), using EclipseMode plugin.
Get the most out of it, map Ctrl+S alike saving and compiling tasks simultaneously via JRebel.
Navigating through advanced compilation configs
Leveraging external compilers
With IntelliJ IDEA versions 12 and beyond, enable an external compiler for a seamless automatic build process. This trick keeps your project updated while preserving IDE performance.
Spring Boot DevTools integration
Working with Spring Boot apps? Incorporate Spring Boot DevTools for hot deployment. Live reload with each code change, no server restarts - total win.
Embracing incremental builds
Opt for Build | Make (Ctrl+F9) in IntelliJ IDEA. It compiles changed and dependent files incrementally. A smarter alternative to full-project compilation, saves you time, coffee, and sanity!
Avoid Overhead: Switch plugins wisely
EclipseMode plugin, useful for IntelliJ versions below 12, might hit brakes on IntelliJ IDEA versions post 12 due to performance issues. Explore the official FAQ for efficient building alternatives.
