Cannot use KotlinPoet version 1.7.0 with Java 8

[martinbonnin]

The latest 1.7.0 version declares "org.gradle.jvm.version": 11 which makes it impossible to compile for Java 8:

      > No matching variant of com.squareup:kotlinpoet:1.7.0 was found. The consumer was configured to find an API of a library compatible with Java 8, preferably in the form of class files, and its dependencies declared externally, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm' but:
          - Variant 'apiElements' capability com.squareup:kotlinpoet:1.7.0 declares an API of a library, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm':
              - Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8
          - Variant 'runtimeElements' capability com.squareup:kotlinpoet:1.7.0 declares a runtime of a library, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm':
              - Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8

1.7.1 has been published and should be available shortly. Thanks for reporting!

The deployment JDK shouldn't matter. The fix is to declare 8 as the source/target compatibility which will get propagated into Gradle metadata.
