内置 .jar 文件（内置于 Netbeans 11.2 maven）无法连接到 mysql

Question

我已经在 Maven Netbeans 中构建了一个应用程序。此应用程序正在从 Jforms 和 Jdialog 获取所有数据并将其存储在 MySQL 中。当我运行在 NetBeans 中运行此应用程序时它工作正常，但是当我尝试运行构建的 jar 文件时它无法与 MySQL 通信。

我试过使用依赖项构建项目，但它不起作用。当我从 Netbeans 运行ning 时的输出如下：-

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true

--- exec-maven-plugin:1.5.0:exec (default-cli) @ CASYS_V3 ---

pom文件如下：-

感谢大家的帮助。我已经在 pom 文件中添加了所有依赖项。它现在正在工作。插件如下：-

     <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>com.mycompany.casys_v3.StartPage</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
      <executions>
        <execution>
          <id>make-assembly</id> 
          <phase>package</phase> <!-- packaging phase -->
          <goals>
            <goal>single</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
