Anyone else getting unresolved references after migrating from experimental to 1.3?

[orangy]

Some details about an error would be helpful

[luke_c]

Upgraded Kotlin plugin and version to 1.3.0

Removed

kotlin {
    experimental {
        coroutines "enable"
    }
}

Replaced

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:0.19.3'

With

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.0.0'
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.0.0'

Now I’m getting unresolved reference: DefaultDispatcher, lauch, UI, etc

did you remove ‘experimental’ from all the import statements?

[luke_c]

Imports changed from

import kotlinx.coroutines.experimental.DefaultDispatcher
import kotlinx.coroutines.experimental.launch
import kotlin.coroutines.experimental.CoroutineContext
import kotlinx.coroutines.experimental.android.UI

to

import kotlinx.coroutines.DefaultDispatcher
import kotlinx.coroutines.launch
import kotlin.coroutines.CoroutineContext
import kotlinx.coroutines.android.UI

[luke_c]

@yole yes (the migrations tool did that)

[louiscad]

@luke_c Would you send a screenshot of the imports here in this thread?

After running migrations

@luke_c After checking the dependencies are properly resolved, I'd try a gradle build from command line to see if it compiles, and if it does, try invalidate caches and restart. Otherwise, try to fix compilation issues, and let us know of any struggle or success

please read the migration guide: https://github.com/Kotlin/kotlinx.coroutines/blob/master/COMPATIBILITY.md#migration-to-100-version-with-kotlin-13

There was a lot of changes between 0.19.0 and 1.0.0 and some of them were breaking (e.g. removal of DefaultDispatcher).

In version 0.30.2 all such API is deprecated with proper replacements, so it is worth to update to 0.30.2 first

perfect, thanks
