执行 maven jar 时出错

Question

我想执行一个 maven jar 时遇到问题。我不明白为什么。我认为 maven 不会导出依赖项，但我不明白为什么。

我的错误：

还有我的 POM.xml：

你能帮帮我吗？

Answer 1

转到您的项目 =>右键单击 => 运行方式 => Maven 构建...（有 3 个尾随点） =>在目标中写入 clean install

它将在目标文件夹中创建两个 jars。

a) WD-Automation-1.0.0-SNAPSHOT.jar

b) WD-Automation-1.0.0-SNAPSHOT-jar-with-dependencies.jar

第二个 jar 是可运行的。将它放在你的 chrome 驱动程序所在的位置并转到 jar 的位置并运行它，它会工作。

Answer 2

我认为你使用了错误的 jar 文件。

生成的具有依赖关系的 jar 文件应位于项目的“target/lib”中 (${project.build.directory}/lib)，而不是 maven 存储库。
