Question

我无法将maven项目从Java 8迁移到Java11。我该如何解决模块依赖性？

我已经定义了模块module-info.java并从命令行编译为 mvn clean install运作良好，但无法在IntelliJ IDEA中运行项目。

module etu.wollen.vk {
    requires java.sql;
    requires sqlite.jdbc;
    requires json.simple;
    exports etu.wollen.vk;
}

我在IDE中遇到了很多错误：

我以前遇到过这个确切的问题，我相信我通过添加以下依赖项来解决此问题：

<dependency>
    <groupId>org.hamcrest</groupId>
    <artifactId>hamcrest-core</artifactId>
    <version>2.1</version>
    <scope>test</scope>
</dependency>

如果这不能解决您的问题，请告诉我。
