以上是我的POM.xml

问题
当双击project.exe时，没有执行任何操作。没有任何内容。执行project.exe后没有任何反应这段代码有什么不对吗？我错过了什么？还需要安装什么或什么？是的，请一步一步指导我，thx =）

更新
在我运行cmd java -cp C:\Users\chiny\Desktop\InsertMySQL\target\InsertMySQL-1.0-SNAPSHOT.jar com.mycompany.insertmysql.insert来解决java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

之后

所以，我已经搜索了解决方案，只是提到添加依赖项，正如您所看到的，我的pom.xml已经附加了依赖mysql连接器。我不知道如何解决它

更新2

我得到这个错误怎么样？这是什么？

所有问题都是CLASSPATH，java找不到mysql-connector-java.jar路径。怎么解决？

但是当我使用java -cp .;C:\Users\chiny\.m2\repository\mysql\mysql-connector-java\5.1.45\mysql-connector-java-5.1.45.jar;C:\Users\chiny\Desktop\InsertMySQL\target\InsertMySQL-1.0-SNAPSHOT.jar com.mycompany.insertmysql.insert运行mysql-connector-java-5.1.45.jar时，project.exe能够运行..如何以编程方式设置nysql连接器类路径？

Answer 1

您正在创建一个阴影jar文件以包含所有必需的依赖项，但在launch4j插件的配置中，您引用了无阴影的jar文件。更新插件配置以使用正确的jar：

<jar>target/InsertMySQL-1.0-SNAPSHOT-shaded.jar</jar>

执行Maven launch4j .exe
