Intellij Java Maven Gson 导入不起作用 - 包不存在
Intellij Java Maven Gson import doesn't work - package doesn't exist
我想使用 com.google 中的 gson 库并尝试通过 pom、模块 maven 导入等将它添加到我的 Maven 项目中,但即使它出现在我的外部库中,Intellij告诉我,那个包不存在。我尝试了重新加载、重新启动、删除它、使 chache 无效等,但没有任何帮助,有人可以帮忙吗?
import com.google.gson
以及具体的错误代码:
Error:(9, 18) java: package com.google does not exist

你导入错误com.google.gson;
它应该被替换为 import com.google.gson.* 或 import com.google.gson.Gson,如果这没有帮助,尝试通过 Maven 工具重新导入依赖项,(screenshot)。
希望能有所帮助。
转到“文件”->“项目结构”,单击enter image description here 一侧的“库”选项卡。您可以添加或删除任何库。
