Version 1.8.0 and compatibility with java8

[fserafin]

Hi, if I use the plugin version 1.8.0 in a java8 project, I get this error: Unsupported class file major version 63. I'm using Gradle 7.5.1, SDK Temurin 1.8.0_382.

I tried with an empty project and this is my build.gradle:

plugins {
    id 'java'

    id 'org.cyclonedx.bom' version '1.8.0'

}

group = 'org.example'
version = '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    testImplementation platform('org.junit:junit-bom:5.9.1')
    testImplementation 'org.junit.jupiter:junit-jupiter'
}

test {
    useJUnitPlatform()
}

This is the error that I get:

If I switch to previous version 1.7.4 everything works fine.

I've been seeing similar problems and Google led me here. Apparently it's a bug with Gradle itself: https://github.com/gradle/gradle/issues/24390

Having a read through that issue it sounds like the solution is just upgrading to a newer version of Gradle.
