Spring-boot and Gradle: too long build time - how to debug?

Question

I have multipart project and API part of the project has around 10 dependencies.

Trying to run API project with Spring Boot(bootRun) and everything works but build time too long. I have tried to build it with gradle parallel and daemon already but it does not work.

How I can debug build process to understand what is take long time?

Update:

gradle build with --debug goes to this point and stack for few minutes

13:53:54.215 [DEBUG] [org.gradle.api.internal.artifacts.ivyservice.resolveengine.result.StreamingResolutionResultBuilder$RootFactory] Loaded resolution results (0.003 secs) from Binary store in /private/var/folders/jg/94cgy2fs2mqckt3mx4fj52qm0000gn/T/gradle8000416708924643404.bin (exist: true)
> Building 0% > Resolving dependencies ':web-sb-api:runtime'

stack here for 2-3 minute and after that continue with really long trace...

Answer 1

You can try to run your build with -d or --debug flag to run your build with debug logging level. May be additional output will be usefull to find the reason, why your build runs so long.
