[SOLVED] java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/Math8 when upgrading Gradle and Android Gradle Plugin

java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/Math8 when upgrading Gradle and Android Gradle Plugin

I'm working on an Android app with a Gradle version of 7.1.1 and an Android Gradle Plugin version of 7.0.0. When I upgrade to Gradle version 7.2 and Android Gradle Plugin version 7.1.1, I get the following error.

The error is coming from this code:

fun toLocalStartOfDay(date: Long): Instant = Instant.ofEpochMilli(date)
    .atZone(ZoneId.systemDefault())
    .withHour(0)
    .withMinute(0)
    .withSecond(0)
    .withNano(0)
    .toInstant()

The build.gradle file is set to target JVM 1.8 with desugaring.

compileOptions {
    coreLibraryDesugaringEnabled = true
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = '1.8'
}

The desugar_jdk_libs version is set to 1.0.9.

versions.androidDesugaringVersion = '1.0.9'
support.android_desugaring = "com.android.tools:desugar_jdk_libs:$versions.androidDesugaringVersion"

Why would upgrading cause this error?

Solution

Desugaring effects "a subset of java.time" so upgrading to the latest version of desugar_jdk_libs should fix the issue. At the time of posting, the latest version is 1.1.5.
