1.14 - hot swap fails in IDEA

[anothertime]

Hi i'm using IDEA but when I modify my mod code and then rebuild it, while debugging, I keep getting "hot swap falied" errors and I'm forced to restart MC to test the new code. I generated the run configs with get the genIntellijRuns task and I've never had this problem in 1.12

 

I'm using the last version of IDEA and forge 1.14.4-28.1.102

 

How could i fix this problem?

thank you!

What kind of changes?

Changes to the body of an existing method

Are you running the build manually with a gradle task or are you clicking run -> reload changed classes?

[anothertime]

I usually rebuild the module with build\build module but I've also tried run\reload changes after looking for a solution on the web but the result is the same

Sorry to bump, but this is really slowing down development. Is this a problem with ForgeGradle or could be IDEA ?

I did more tests. It works with a single mod (I compiled and debugged the forge 106 mdk) but it doesn't works with a multi-mod project structure: I always get the hot swap error. I followed McJty example to build my multi-mod project:

I think I can confirm that this is a gradle/forgegradle problem. I configured IDEA to NOT use gradle to build/run my project and now the hot swap work correctly

Please, how did you configure it?

https://www.jetbrains.com/help/idea/gradle-settings.html  <---  this does not solve the problem, it says that there are not do change

 

I have the same problem but I am working with only one project....

I also had the same problem and I this is how I solved it:

1. Open "Settings" -> "Build, Execution, Deployment" -> "Gradle".
2. In the "Gradle projects" section select your project.
3. "Build and run using:" is set to "Gradle". Select "IntelliJ IDEA" instead.

I don't know why this solves the problem and what consequences this may have (e.g., maybe you will have to manually run some gradle tasks each time you change forge version, etc), but this does allows you to use Hot Swap.
