Error:(10, 18) java: package com.google.gson is not visible
(package com.google.gson is declared in module gson, but module AnimalShelter fails to read it)
在向我的Maven添加 gson 依赖项后出现此错误,我完全不知道如何解决它,我在Google上四处搜寻,建议我放置一个必需的在我的 module-info.java 中。做到了,它修复了IDE错误,但是当我尝试运行时
java.lang.module.FindException: Module gson not found, required by AnimalShelter
老实说,我根本不了解模块的工作方式,因此我可能会忽略一些简单的事情,但是在我的maven pom.xml中添加依赖项后,它不应该工作吗?
如下所示。pom.xml :(已导入)

您可以尝试以下选项:
尝试使用最新版本的Gson
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.5</version>
<scope>provided</scope>
</dependency>

使用Maven的provided范围意味着不需要将依赖关系与您的应用程序打包在一起(即,您正在部署到将提供依赖关系的Tomcat之类的应用服务器上)。尝试一起删除范围,或更改为默认的 compile 。
