运行 来自 IntelliJ IDEA 的 SpringBoot 应用程序无法用于模块化项目
Running SpringBoot app from IntelliJ IDEA fails for modular project
我的项目是一个 Spring 启动应用程序，其中包含一个 java 模块。此模块不 open 它的任何软件包。
模块-info.java
module my.somewhere
{
requires spring.core;
requires spring.context;
requires spring.boot;
// and so on
}
从命令行 mvn clean spring-boot:run.
调用时，应用 运行 如预期
但是当我尝试从 SpringBootApplication 的主要方法启动它时，控制台中出现以下错误：java.lang.IllegalAccessException: module my.somewhere does not open my.somewhere.abc to module spring.core（请参阅下面的详细堆栈）。
由于其反射操作，将某些内容打开 Spring 看起来是合理的，但我想知道为什么 maven 设法 运行 它没有问题。
请帮助我了解如何从 Maven 3.6.1 和 IntelliJ IDEA 2019.3.
中类似地制作应用程序 运行
