测试结果

配置 JAVA_TOOL_OPTIONS

无效

# 配置 JAVA_TOOL_OPTIONS  -Dsun.stdout.encoding=GBK -Dsun.stderr.encoding=GBK -Dfile.encoding=GBK

> Task :runCode
涓枃娴嬭瘯
sun.stdout.encoding = UTF-8
sun.stderr.encoding = UTF-8
      file.encoding = GBK
    native.encoding = GBK

配置 build.gradle.kts

有效

tasks.withType(JavaExec::class.java) {
    val args:ListString> = ArrayList()
    args.addLast("-Dsun.stdout.encoding=GBK")
    args.addLast("-Dsun.stderr.encoding=GBK")
    args.addLast("-Dfile.encoding=GBK")
    this.jvmArgs = args
    println(this.jvmArgs)
}

> Task :runCode
中文测试
sun.stdout.encoding = GBK
sun.stderr.encoding = GBK
      file.encoding = GBK
    native.encoding = GBK

配置 idea64.exe.vmoptions

无效

-Dsun.stdout.encoding=GBK
-Dsun.stderr.encoding=GBK
-Dfile.encoding=GBK

> Task :runCode
涓枃娴嬭瘯
sun.stdout.encoding = UTF-8
sun.stderr.encoding = UTF-8
      file.encoding = GBK
    native.encoding = GBK

无配置

无效

> Task :runCode
涓枃娴嬭瘯
sun.stdout.encoding = UTF-8
sun.stderr.encoding = UTF-8
      file.encoding = GBK
    native.encoding = GBK

总结

只有配置JavaExec 运行环境才能不乱码，配置了JAVA_TOOL_OPTIONS，可以在VSCode 中 PowerShell 执行任务中日志不乱码，但是执行结果还是乱码。
