IntelliJ 中的调试（重新加载更改的类）

Question

I recently switched from eclipse to IntelliJ. Eclipse's debug launcher used to reload the application instantly, whenever a class was saved. IntelliJ takes more than 10 secs to reload changed classes, which might not be a lot, but it is annoying because I use it so frequently.

How to make IntelliJ reload changed classes faster?

Answer 1

To reload changed classes

1. Do one of the following:

• On the main menu, choose Run | Debugging Actions | Reload Changed Classes.
• On the main menu, choose Build | Compile "class_name" to recompile an altered class during debug.

2. In the Reload Changed Classes dialog box, confirm reloading. Results are displayed in the Messages tool window.

Refer this link for detailed explanation.

Answer 2

InteliJ is not recompiling the code after change in java files and rebuilding

1. Project > Setting>Build,Execution,Deployment>Compiler>check "build project automatically"

2. Ctrl + Shift + A find "registry", according to your requirements check the following:

    compiler.automake.allow.when.app.running compiler.automake.trigger.delay=500

3. Add devtool in pom.xml :

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

4. Build, If found any probelm while building, saying some jar in not in class path. Just delete the corrupted jar and re-build the project angain after sync with maven libb
