一般信息：我在版本git-Spigot-1d14d5f-ba32592（MC：1.8.3）中使用Bukkit / Spigot API（实现API版本1.8.3-R0.1-SNAPSHOT ），IntelliJ IDEA 14.1.3并使用其默认编译器进行编译。 java jdk版本是1.8.0_25。
因此，当我尝试调用此类的构造函数时，它会从标题中抛出运行时异常。

正如你所看到的那样，构造函数在那里，并且据我所知正确调用。那么这个错误在我的项目设置，API事物或完全不同的东西中是错误的吗？
实用程序类位于一个单独的模块中，如果我将它们粘贴到我的测试插件模块中，一切都可以工作，但不能在其他模块中。但是， me.lakan.util.inventory 中任何其他类中的任何其他构造函数都可以正常调用。
答案 0 :(得分：3)
问题出在项目结构中。
对于测试工件，我选择了util模块的模块输出。 将其更改为util模块的工件输出可修复它。
