Question

Is there any way in 1 4+ to figure out why kapt is non incremental for a build I searched previous messages and people suggest downgrading to 1 3x which is basically impossible in our app

ephemient · Answer

` gradlew Pkapt verbose=true` or the equivalent in gradle properties should print out some information about that

Sha Sha Chu · Answer

yes i see `Incremental annotation processing apt mode false` but it doesn t tell me why it didn t run incrementally

Sha Sha Chu · Answer

in this blog post from 2019 <https medium com daniel novak making incremental kapt work speed up your kotlin projects 539db1a771cf> it says that it should log the processors that aren t incremental but it doesn t appear to anymore

ephemient · Answer

and you haven t turned off incremental kapt `kapt incremental apt=false` or incremental compilation `kapt incremental=false` hmm

Sha Sha Chu · Answer

no

Sha Sha Chu · Answer

i m looking into the `kapt` source code and it looks like there are some other cases when it will turn off incremental kapt

Sha Sha Chu · Answer

```if logger isInfoEnabled val time = Took $ System currentTimeMillis startTime ms when previousSnapshot == UnknownSnapshot gt Initializing classpath information for KAPT $time classpathChanges == KaptClasspathChanges Unknown gt Unable to use existing data re initializing classpath information for KAPT $time else gt classpathChanges as KaptClasspathChanges Known Full list of impacted classpath names $ classpathChanges names $time ```

Sha Sha Chu · Answer

that s from `KaptTask`

Sha Sha Chu · Answer

so i wonder if i m hitting one of those cases where the classpath changes unexpectedely

ephemient · Answer

` gradlew info` or ` i` would show those and a lot of other stuff

Sha Sha Chu · Answer

i do see this in the logs `Unable to use existing data re initializing classpath information for KAPT Took 781ms ` i guess if any files get added to the classpath `kapt` can t run incrementally earlier in the logs i see ```Task xxxxxx kaptDebugKotlin is not up to date because Input property classpathStructure$kotlin gradle plugin file Users shasha gradle caches transforms 3 c10f7f9ca3457239899004135492aca1 transformed output bin has been added Input property classpathStructure$kotlin gradle plugin file Users shasha gradle caches transforms 3 418b18a8eb2bb12415828065185d47c2 transformed output bin has been added Input property classpathStructure$kotlin gradle plugin file Users shasha gradle caches transforms 3 0e350fdc77bcd8b6930cec8da974a4e2 transformed output bin has been added ``` i don t actually know what those transformed files are

xxxxxx kaptDebugKotlin shouldn t be up to date if you changed something in your sources You changed something right Or you see it every time you run the task
