Java 类不编译在具有 Maven 依赖项的 netbeans 之外工作

Question

我已经用 Java 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，一切都会编译并运行。当我清理和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，它会创建一个可执行的“胖”jar，并合并所有依赖项。所以在你执行了 maven clean 和 package 目标之后，你应该像这样从命令行运行这个 jar：

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