I am trying to add Compose to an existing project, however i get this error:

java.lang.AssertionError: Unbound symbols not allowed

Execution failed for task ':app:compileOmbordsalgStagingDebugKotlin'.
> Internal compiler error. See log for more details

Runtime JAR files in the classpath should have the same version. These files were found in the classpath: And then a loooooong list of Unbound public symbol for public kotlinx.android.synthetic...... Anyone know how to fix this?

I actually just ran into the same thing. Curious what the solution is.

iirc this is because synthetics and the kotlinc IR backend don't agree with each other; not sure it's compose-specific but since compose requires the IR backend, the two can't be used together

I think it is fixed in 1.4.20 🙂

Hmm I didn’t have synthetics in my case. Haven’t been able to debug it yet. Good to know there’s a fix in a future version. That’s 1.4.20 of the compiler right @shikasd.

Navigation doesn't use synthetics, no
