the 30 seconds should only be spent on the first build. incremental build should only rebuild the files you changed

yeah, but if you switch branches, you have almost to clean again or IDE throws an error, or if you introduce a new class or method or field, the `generateStubs` need to be invoked it just much slower than a "normal" incremental build and on slower PC it costs time :confused:

&gt; or IDE throws an error
What error are you talking about?

Stub generation task supports incremental compilation, just as the normal compileKotlin task. If it isn’t true for you then it’s a bug.

does kotlin annotation processing also support incremental compilation?

`kaptGenerateStubs…Kotlin` task supports incremental compilation. `kapt...Kotlin` (the second task) does not (and it’s technically impossible).

<@U0B99LPPW> could you explain me why it is impossible to incremental compile kapt? some simple explanation for dummys like me? :slightly_smiling_face:

Kapt task does not compile everything, it just invokes javac in order to launch annotation processing. AP itself can’t be incremental as JSR269 does not provide any support for that.
