Java class 无法在具有 maven 依赖项的 netbeans 之外进行编译

Question

我已经在 Java 中创建了一个项目。我添加了一个 Maven 依赖项，nimbus-jose-jwt。

我的 pom.xml 文件：

当我在 netbeans 中运行时，一切都会编译并且运行s。当我清理并构建并尝试通过命令行运行时，我收到以下错误：

error: package com.nimbusds.jose does not exist

这是我第一次使用maven，所以我对此很陌生。

您的 pom 文件中有 maven-shade-plugin，它创建了一个可执行文件 "fat" jar，其中合并了所有依赖项。所以在你执行 maven clean 和 package 目标之后，你应该从命令行运行这个 jar 像这样：

java -jar target/vertxTestProject-1.0-SNAPSHOT-fat.jar
