Broken testTargetsForShard

[inehemiasm]

Hi, i am trying to distribute a set of tests A on one shard and set of testsB on a separate shard. I assume that't the solution would be to configure something like this:

testTargetsForShard.set( 
  project.provider { 
    listOf( 
      "class com.example.testsA",
      "class com.example.testsB"
    )
  }
) 

when i execute ./gradlew printYml i noticed that it's set properly

test-targets-for-shard: 
   - class com.example.testsA"
   - class com.example.testsB"

However, when i execute ./gradlew runFlank
I get the following error:

RunTests

It seems that it tries to grab android_shards.json file that was never generated. Unless the user have to manually provide it

[runningcode]

This seems like a bug in flank. What version of flank are you using?

[philite]

Hello, I found the same problem. I did try using from flankVersion = "21.01.1" to latest flank version and still not getting it work either.

[moetouban]

i have the same issue as well version: v22.05.0. have you find out what is causing it and how to fix ?

[moetouban]

@runningcode this issue doesn't happen on flank v22.05.0
I print the yaml config file generated from fladle and noticed one thing off which is
custom-sharding-json: null if I remove this flag and run the config directly through flank I don't have the issue anymore.
This flag seems to be generated from the fladle plugin.
