At first glance it looks like conflicting dependencies in the buildscript classpath Can you post the build results with ` stacktrace`

mbonnin · Answer

My guess is that it fails on ```private val UTF8 BOM = EFBBBF decodeHex ``` That s most likely because you have an older okio version in your `buildSrc` classpath

mbonnin · Answer

Can you update okio in your buildSrc to `2 5 0`

mbonnin · Answer

If okio is included transitively you might have to add it

wingchi · Answer

Added it same stacktrace

mbonnin · Answer

bummer

mbonnin · Answer

Can you add the whole apollo gradle plugin in buildSrc maybe

mbonnin · Answer

I m pretty sure it comes from this <https github com gradle gradle issues 4741>

mbonnin · Answer

Basically dependencies in buildSrc override the ones in other parts of your build scripts and might cause runtime crashes like this

mbonnin · Answer

Something else you can try to debug is run ` gradlew buildEnvironment` That ll should tell you waht `okio` and `apollo compiler` dependencies are used

wingchi · Answer

Interesting I m not seeing apollo show up at all And okio is at `1 16 0`

mbonnin · Answer

gt I m not seeing apollo You might have to run it in your module ` gradlew $module buildEnvironment`

wingchi · Answer

Thanks `apollo compiler 2 0 2` and `okio 2 5 0`

mbonnin · Answer

That sounds appropriate

mbonnin · Answer

I was really suspecting the `decodeHex` method which is a recent addition of okio

wingchi · Answer

I m not sure if this helps but when I ran the build again with a stacktrace I got `Caused by java lang NoClassDefFoundError Could not initialize class com apollographql apollo compiler parser Schema`

mbonnin · Answer

If you have `build gradle kts` files can you try adding something like this at the root of the script ```println test decodeHex toString ``` In the same build gradle kts file where you apply the apollo plugin To make sure okio dependency is working well

wingchi · Answer

Disregard that snippet I pasted the wrong one

mbonnin · Answer

Whatt is different from the first one

wingchi · Answer

I think I just missed the first line It looked off but it s hard to read snippets on slack

mbonnin · Answer

it is

mbonnin · Answer

Last resort solution you can run your build with ` Dorg gradle debug=true` and set breakpoints in intelliJ to have more details where the crash happens

wingchi · Answer

Dumb question do I just drop that `println` anywhere in the root of `build gradle kts`

mbonnin · Answer

yup

mbonnin · Answer

That should fail during configuration so before your actual crash that happens at execution

wingchi · Answer

Yup That does fail in my build

mbonnin · Answer

Something like a missing `ByteString Companion` class

wingchi · Answer

Ohh sorry I put the okio in the wrong `build gradle kts`

wingchi · Answer

That fixed that build issue

mbonnin · Answer

thumbsup

mbonnin · Answer

This gradle feature bug is really annoying

wingchi · Answer

Still getting build errors but the model generation seems to have worked

wingchi · Answer
