在Java中导入toml4j失败

我正试图导入到我的maven项目中。我在依赖项部分的POM.xml中将其添加到我的依赖项中：

<dependency>
    <groupId>com.moandjiezana.toml</groupId>
    <artifactId>toml4j</artifactId>
    <version>0.7.2</version>
</dependency>

在我的主文件中，它不识别“moandjiezana”部分

在此处编辑2:POM.xml完整文件：

我确实安装了JDK，IntelliJ可以识别它

请按照以下步骤操作：-

按照中的说明安装MAVEN。您还应该安装JAVA 7or

设置环境变量（即应设置JAVA HOME和Maven path）

使用maven命令验证安装是否成功

如果Maven版本显示成功，请尝试IntelliJ中的自动导入功能。它应该从远程存储库下载工件

去IntelliJ

打开POM xml文件-->右键单击-->Maven-->重新导入

编辑：-

请确保安装了JDK 7或8，并且正确设置了JAVA_HOME

使用

set JAVA\u HOME=C:\Program Files\JAVA\jdk1.8.0\u 31

正确设置JAVA主页

---

好的，经过进一步的研究，我发现IntelliJ基本上不想写入已经失败的导入文件夹

---

因此，删除要在

C:\user\[user]\.m2\repository

中导入的依赖项文件夹并重新导入应该可以解决问题。

实际上，我可以从maven下载上述工件。希望您可以通过internet访问远程回购下载。我确实可以通过代理服务器连接internet。我甚至可以通过IntelliJ ping存储库@ConferenceQuestintellij具有自动导入功能。转到设置-->搜索“自动导入”。启用它。一旦完成，IntelliJ应该自动从repo获取依赖项。它已经启用，但仍然不起作用。对不起，如果我表现得很愚蠢，但是我对使用maven还相当陌生。你在你的计算机上安装了maven吗？你使用的是windows还是Mac？您是否正确设置了MAVEN环境变量？这是你计算机上的第一个Maven项目吗？
