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

sun.stdout.encoding = UTF-8
sun.stderr.encoding = UTF-8
file.encoding = GBK
native.encoding = GBK
配置 build.gradle.kts
有效

args.addLast("-Dsun.stderr.encoding=GBK")

sun.stdout.encoding = GBK
sun.stderr.encoding = GBK
file.encoding = GBK

配置 idea64.exe.vmoptions
无效

-Dsun.stderr.encoding=GBK
-Dfile.encoding=GBK
> Task :runCode
涓枃娴嬭瘯
sun.stdout.encoding = UTF-8
sun.stderr.encoding = UTF-8

无配置
无效

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。
