Is there setup example how to build android app with annotation processing and kapt with JDK9+

gildor · Answer

kapt works with JDK9+

gildor · Answer

no special config required But particular APs may have own problems

Eugen Martynov · Answer

I have problem with Generated class from JDK

gildor · Answer

For example DataBinding do not work for us even if you solve all problems with jaxb dependency

gildor · Answer

Dagger

Eugen Martynov · Answer

yes

gildor · Answer

it s kapt bug that doesn t propagate target JVM version to annotation processor

Eugen Martynov · Answer

ah if databinding is still issue then I will not even try

gildor · Answer

I m not 100 sure

gildor · Answer

but bindings just not generating

gildor · Answer

no other exceptions just no output

Eugen Martynov · Answer

I found next workaround ``` if project hasProperty kapt Reference for kapt DSL <https kotlinlang org docs reference kapt html java compiler options> kapt we expect this closure to run over a org jetbrains kotlin gradle plugin KaptExtension javacOptions option source 8 option target 8 ```

gildor · Answer

yes it doesn t work for me for some reason

Eugen Martynov · Answer

same

Eugen Martynov · Answer

oke thank you

gildor · Answer

So I use com github pengrad jdk9 deps

gildor · Answer

gildor · Answer

this is just a dependency with Generated annotation

gildor · Answer

so it solves problem for me but again looks that binding do not work for some reason

Eugen Martynov · Answer

oke let me check google state about jdk9 and databinding

gildor · Answer

Could you try to build you project with fixed dagger

Eugen Martynov · Answer

I will try today after lunch

Eugen Martynov · Answer

I will keep you updated

gildor · Answer

Thanks

Sergey Chelombitko · Answer

` source 8` works well in kotlin android modules but broken in pure kotlin modules <https youtrack jetbrains com issue KT 33028>

gildor · Answer

< Sergey Chelombitko> Thanks

Eugen Martynov · Answer

< gildor> After just adding your suggested dependency I have ```java lang NoClassDefFoundError javax xml bind JAXBException```

gildor · Answer

Yes it s from bindings

gildor · Answer

Try to add Jaxb dependencies to kapt classpath ``` kapt javax xml bind jaxb api 2 3 1 kapt com sun xml bind jaxb core 2 3 0 1 kapt com sun xml bind jaxb impl 2 3 2 ```

gildor · Answer

for some reason I also had this problem until I add the same to `annotationProcessor` classpath but not sure why

Eugen Martynov · Answer

I should check databinding sources

Eugen Martynov · Answer

probably why use it for xml parsing or whatever

gildor · Answer

Yes of course

gildor · Answer

Anyway because Jaxb removed from JVM default classes you have to add it

gildor · Answer

Could you please try Also add this ``` annotationProcessor javax xml bind jaxb api 2 3 1 annotationProcessor com sun xml bind jaxb core 2 3 0 1 annotationProcessor com sun xml bind jaxb impl 2 3 2 ```

gildor · Answer

I m not sure is it required or not but looks like that even tho we don t use Java APT directly I would expect that Kapt should populate it for APT but I don t have any real information is it correct or not I just tried to make it work

Eugen Martynov · Answer

It is required if you still have somewhere java class with databinding

gildor · Answer

Yes but I would expect that Kapt sets own classpath to APT

Eugen Martynov · Answer

oke

Eugen Martynov · Answer

I m on the final stages

Eugen Martynov · Answer

`compileDebugJavaWithJavac` fails with the same class missing

gildor · Answer

even with annotationProcessor

Eugen Martynov · Answer

it fixes

Eugen Martynov · Answer

I added it to the gradle file that is applied for all subprojects

Eugen Martynov · Answer

but looks like app is not in this set

Eugen Martynov · Answer

final strokes

Eugen Martynov · Answer

it is green

Eugen Martynov · Answer

let see if everything is correctly generated working

Eugen Martynov · Answer

I see data binding generated classes

gildor · Answer

Nice

Eugen Martynov · Answer

The apk file looks correct Installing

Eugen Martynov · Answer

It runs

Eugen Martynov · Answer
