or gradle.properties

@h0tk3y pinned a message to this channel.

with single line changed gradle build in Android Studio(except first clean build) takes ~16 seconds for me, not sure if its better than before, maybe I am not doing it right

is adding kotlin.incremental=true to gradle.properties enough?

I also have

org.gradle.daemon=true

in that file

and instant run disabled

@damianpetla: do you use kotlin 1.0.2?

@damianpetla: could you please check how much time takes the same case w/o

kotlin.incremental=true

I use 1.0.2, will check that

@damianpetla: yes, to enable IC in gradle adding "kotlin.incremental=true" to either gradle.properties or local.properties should be enough. After that there should be a warning "Using experimental kotlin incremental compilation" in the output. The first build after enabling IC won't be incremental.

do I have to kill gradle daemon process each time I change

kotlin.incremental

?

it looks like I don’t have to

@bashor: I have tried that and changing single line with IC=false takes ~26sec, with IC=true it takes ~15sec

so I guess it’s a win simple smile

@damianpetla: did you run it some times (>1)?

at least 3 times each

@damianpetla: nice, thanks

I wonder if it matters that I am using apt plugin + dagger2 android databinding and some classes in Java? What if I remove all of that and replace with kotlin classes, would that make a difference?

is it opensource? or could you share lines which you changed?

@bashor: it is private source, quite big with multidex and many libraries but basically I was adding and removing

println()

with different texts in one class

but for my test I have minSdk=21 so ignore multidex

we make incrementaly only kotlin. Right now we process changes in Java less precise than in Kotlin

is there a KotlinPoet in the works yet?

🤒

oh 😞

we've talked about one
