Gradle kotlinx-coroutines-bom error with armeria 0.98.x

[DasAmpharos]

I'm attempting to use armeria 0.98.x with gradle and am receiving the following error:

Could not resolve all files for configuration ':{PROJECT_NAME}:detachedConfiguration40'.
> Could not resolve org.jetbrains.kotlinx:kotlinx-coroutines-bom:1.3.3.
  Required by:
      project :{PROJECT_NAME}
   > Cannot choose between the following variants of org.jetbrains.kotlinx:kotlinx-coroutines-bom:1.3.3:
       - enforcedRuntimeElements
       - runtimeElements
     All of them match the consumer attributes:
       - Variant 'enforcedRuntimeElements' capability org.jetbrains.kotlinx:kotlinx-coroutines-bom:1.3.3:
           - Unmatched attributes:
               - Found org.gradle.category 'enforced-platform' but wasn't required.
               - Found org.gradle.status 'release' but wasn't required.
               - Found org.gradle.usage 'java-runtime' but wasn't required.
       - Variant 'runtimeElements' capability org.jetbrains.kotlinx:kotlinx-coroutines-bom:1.3.3:
           - Unmatched attributes:
               - Found org.gradle.category 'platform' but wasn't required.

               - Found org.gradle.usage 'java-runtime' but wasn't required.

This is what my gradle file looks like:

apply plugin: "org.springframework.boot"
apply plugin: "io.spring.dependency-management"

dependencyManagement {
    imports {
        mavenBom "com.linecorp.armeria:armeria-bom:0.98.1"
        mavenBom "io.netty:netty-bom:4.1.45.Final"
    }
}

dependencies {
    api("com.linecorp.armeria:armeria-grpc")
    api("com.linecorp.armeria:armeria-spring-boot-webflux-starter")
    runtime("com.linecorp.armeria:armeria-spring-boot-actuator-starter")
}

tasks.withType(JavaCompile) {
    sourceCompatibility = "1.8"
    targetCompatibility = "1.8"
    options.compilerArgs += "-parameters"
    options.encoding = "UTF-8"
    options.debug = true
}

When I downgrade to 0.97.0, the issue goes away.

This is probably because upgrading our spring-boot dependency version also bumped a dependency on kotlin-coroutines which doesn't work correctly with older spring-dependencies plugin.

spring-gradle-plugins/dependency-management-plugin#263 (comment)

No clue why spring boot would even have a dependency on Kotlin...

But the issue seems to be fixed in the latest version of the dependencies plugin, 1.0.9.RELEASE. Can you try updating it?

I had the same issue. Updating the dependencies plugin to 1.0.9.RELEASE fixed the issue.
