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?
CodePudding user response：
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.
