Recently, I encountered a weird issue with coroutines in Kotlin. A library that references a coroutine version that differed from my Kotlin’s coroutine could not compile. It resulted in the following error being displayed.<\/p>\n\n\n\n
Cannot access 'kotlinx.coroutines.CoroutineScope' which is a supertype of '.....'.<\/pre>\n\n\n\nThis is probably related to an Application Binary Interface (ABI) issue where a low-level C compiled code has some non-breaking changes but as the ABI has changed, a recompilation is required. In this case, I could either recompile Kotlin coroutines + referenced library, or I could just state the same exact coroutine version used by the referenced library.<\/p>\n\n\n\n
In my Gradle build (build.gradle) file, I added this new line:<\/p>\n\n\n\n
compile group: 'org.jetbrains.kotlinx', name: 'kotlinx-coroutines-core', version: coroutinesVersion<\/pre>\n\n\n\nAnd in my Gradle properties (gradle.properties) file, I specified my the variable:<\/p>\n\n\n\n
coroutinesVersion=1.3.2<\/pre>\n\n\n\nIf you’re using Maven, then you can change your configuration like this:<\/p>\n\n\n\n
<properties>\n <coroutines.version>1.3.2<\/kotlin.version>\n<\/properties>\n...\n<dependency>\n <groupId>org.jetbrains.kotlinx<\/groupId>\n <artifactId>kotlinx-coroutines-core<\/artifactId>\n <version>${coroutines.version}<\/version>\n<\/dependency><\/pre>\n\n\n\nThe fix is absurdly easy despite of the weird and cryptic error message. I hope this was helpful to you and helped you understood what might have happened to cause this issue to occur. <\/p>\n","protected":false},"excerpt":{"rendered":"
