您可以像這樣配置您的 Maven 程序集插件（您不需要其他插件）。這會將所有 .class 文件放入您的 jar 中。
mvn clean install生成你的jar，然后java -jar target/yourJar-jar-with-dependencies.jar執行。有關更多詳細信息，請查看http://maven.apache.org/plugins/maven-assembly-plugin/
我給你留了一個改進的 maven 3 的 pom 文件（實際上問題出在這個版本的 maven 上不可用的 pluginManagement 標簽）。您也不需要 maven jar 插件。
請找到這兩個模式以獲取完整的詳細信息
