Forge Java模组开发：mysql-connector-java依赖打包后失效求助

我已经花了两周时间尝试为我的Forge Java模组添加mysql-connector-java依赖，目的是实现客户端与SQL服务器的连接。在IDE开发环境中，代码可以正常连接服务器并执行数据库操作，但打包后的客户端完全无法实现该功能。

我尝试过使用com.github.johnrengelman.shadow插件将依赖打包进模组Jar包，但操作后要么没有效果，要么出现错误；多次执行shadowJar命令（搭配不同选项）也没能解决问题。

以下是我的相关配置、错误日志和测试代码：

gradle.build 配置 #

plugins {
    id 'java'
    id 'net.minecraftforge.gradle' version '5.1.+'
    id 'com.github.johnrengelman.shadow' version '7.1.2'
}

version = '1.0'
group = 'com.example.mymod'
archivesBaseName = 'mymod-1.19.2'

java.toolchain.languageVersion = JavaLanguageVersion.of(17)

minecraft {
    mappings channel: 'official', version: '1.19.2'

    runs {
        client {
            workingDirectory project.file('run')
            property 'forge.logging.markers', 'REGISTRIES'
            property 'forge.logging.console.level', 'debug'
            mods {
                mymod {
                    source sourceSets.main
                }
            }
        }
    }
}

repositories {
    mavenCentral()
}

dependencies {
    minecraft 'net.minecraftforge:forge:1.19.2-43.2.0'
    implementation 'mysql:mysql-connector-java:8.0.33'
}

shadowJar {
    relocate 'com.mysql', 'com.example.mymod.libs.mysql'
}

测试代码 #

try {
    Class.forName("com.mysql.jdbc.Driver");
    Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "User", "Password");
    String sql = "INSERT INTO chat_messages (Test) VALUES (?)";
    PreparedStatement statement = connection.prepareStatement(sql);
    statement.setString(1, Test);
    statement.executeUpdate();
    statement.close();
} catch (SQLException e) {
    System.out.println(e.getMessage());
} catch (ClassNotFoundException e) {
    e.printStackTrace();
}

希望各位能给出解决思路或具体的配置修改方案，感谢帮助。
