Build Failed - '_BuildScript_' Unsupported class file major version 65

[chaehwanli]

I got build failed with "./gradlew build"

A problem occurred configuring root project 'gradle-dependency-graph-generator-plugin'.
> Could not open cp_proj generic class cache for build file 'C:\GitHubRepo\gradle-dependency-graph\gradle-dependency-graph-generator-plugin\build.gradle' (C:\Users\chaeh\.gradle\caches\7.6.4\scripts\9l1grthz6xnhj84icq5aqh6ud).
   > BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 65  

and I'm using jdk 21

PS >java -version      
openjdk version "21.0.6" 2025-01-21 LTS

OpenJDK 64-Bit Server VM Temurin-21.0.6+7 (build 21.0.6+7-LTS, mixed mode, sharing)

is there any specific java version to build?

[chaehwanli]

it is fixed with JDK 17. :)

I got new build error like below

Could not determine the dependencies of task ':compileKotlin'.
> No matching toolchains found for requested specification: {languageVersion=17, vendor=any, implementation=vendor-specific} for WINDOWS on x86_64.
   > No locally installed toolchains match and toolchain download repositories have not been configured.

And, fixed it with below
gradle.properties

org.gradle.java.home=C:\\Program Files\\AdoptOpenJDK\\jdk-17.0.14+7  // add JDK 17 Path

build error

fixed with

sourceCompatibility = JavaVersion.VERSION_17 // change with Javaversion 17
