I ve already had ```kotlinCompilerExtensionVersion 0 1 0 dev04 ``` adding ```kotlinCompilerVersion 1 3 61 dev withExperimentalGoogleExtensions 20200129 ``` ended up in even more cryptic compiler error

jim · Answer

What was the even more cryptic compiler error

Mate · Answer

Caused by java lang AssertionError Unexpected IR element found during code generation Either code generation for it is not implemented or it should have been lowered FUNCTION REFERENCE private final fun onInject$lambda 0 $this$onInject org foxglove profile ui fragment EditProfileFragment it android text Editable kotlin Unit declared in org foxglove profile ui fragment EditProfileFragment type=kotlin Function1 lt android text Editable kotlin Unit gt origin=LAMBDA

I don t think it is even kapt or compose that fails

Mate · Answer

If I comment out the said method it fails at other place with similar error

jim · Answer

Hmm yeah I assume none of the mentioned classes packages is Compose related That error looks like it might be a bug in the IR backend which is still experimental incomplete but either way it looks like a legitimate bug If you re able to reduce the offending code to a minimal repo we can file a bug against the IR backend to have it investigated further As a workaround if you can move that code into a non compose package assuming it is not related to Compose you can turn off the IR backend in that package and depend on it from your compose widgets

I could locate two kinds of error in my code I ll create the sample project of that but good news is getting rid of that kapt and compose worked together slightly smiling face

Mate · Answer

< jim> Here you can find the project and in the activity two different blocks of code that ends up in build failure

jim · Answer

The first code block is related to coroutines which are known to be incomplete The second code block is more interesting digging into it now Thanks for posting
