Works with com.android.tools.buildG2.0.0-alpha3 but Instant Run doesn’t work on AS until you update to >= alpha5

are you sure you're applying the updated plugin? not only the stdlib?

Duh. Thank you

haha shot in the dark

so yeah, my build hangs on

:project:compileDevMultidexLollipopDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).

I've created https://youtrack.jetbrains.com/issue/KT-10733 to track Kotlin + kapt + incremental Java problems

Hello 👋 I'm having a super annoying issue using kapt for the dagger2 compiler. The problem is when I try to run, it builds; but then runs the ​_previous_​ build on my device, so essentially I have to run twice to see any of my changes, idk if anyone else has run into this I couldn't find anything on S/O

(I'm in Android studio, latest stable build and Kotlin version

1.0.0-beta-4584

)

update: adding

incremental = true

to

dexOptions

in build.gradle seems to fix the build+run issue

Has anyone figures out how to disable incremental java compilation from the build file? I can pass

-Pandroid.incrementalJavaCompile=false

but how can I achieve the same effect using build.gradle?

not really the build file but you can add

android.incrementalJavaCompile=false

to

gradle.properties

should carry the same effect

nice!

this will work for both the projects gradle properties file as well as your global one (

~/.gradle/gradle.properties

)

that makes alpha6 usable again

although it hurts to disable anything incremental

the incremental compiler will not work together with Kotlin, at least with my tests

haven't tried out the latest Kotlin Gradle plugin though

when the kotlin build becomes incremental, I'm converting all my Java code anyway. For now, it's better for the build performance to leave legacy code in Java

@kirillrakhman: try this:

compileJava {
    options.incremental = false
}

I don't think that task exists in an Android project

I tried

tasks.withType(JavaCompile) {
        options.incremental = true
    }

Didn't work

android.applicationVariants.all { variant -> variant.javaCompile.options.incremental = false }

might work

the code above is not wrong. I tried

println(it)

inside the closure and it did print out all the java compile tasks

it's just that setting

options.incremental = false

doesn't do anything

or so it seems

the android plugin will change the value right after you have set it simple smile

ah so it's a timing issue?

yeah, I think the

applicationVariants.all

callback happens after it has been configured from Android plugin's side, so that might work

ok
