Regarding the question, it seems you are using Java older than 17 to run Gradle, have not used JVM toolchains to separate the Java version used to run Gradle from the Java version used to build your project, and have configured `sourceCompatibility` to Java 17.

So the Java &lt;17 you are using to compile complains that it does not know what Java 17 looks like.
