我正在尝试使用 Graal 的原生镜像创建 Spigot 1.15 的原生镜像。我正在使用命令：
native-image -jar spigot-1.15.jar
但是编译失败并出现 NPE：https ://hasteb.in/qujocavi

我尝试使用--intiialize-at-run-time参数，包括net.minecraft.server.v1_15_R1.IRegistry在构建时避免类初始化，但我得到了同样的错误。
所以我的问题是如何将其编译为本机可执行文件？
native-image -jar spigot-1.15.jar您可以通过在 spigotmc 上新下载的 spigot jar 上执行来重现该错误。
