我已经从 Maven 存储库安装了 MariaDB-JDBC-Java 驱动程序 V 3.3.3。当我发出
mvn clean javafx:jlinkjava.lang.ClassNotFoundException: org.mariadb.jdbc.Driver
命令
mvn clean javafx:run请告诉我为什么当我将 mariadb java 连接器的依赖项写入 pom.xml 时，mvn 目标“javafx:jlink”就被破坏了？
我尝试用
pom.xml我希望打包的 java 应用程序通过驱动程序连接到 mariadb 容器，因为它在 cmd 行和 IntelliJ IDEA 上成功完成 - Windows 和 Arch Linux。
-----------------module-info.java
module org.leder.gldisplaymanager {
requires javafx.controls;
requires javafx.fxml;
requires java.sql;
opens org.leder.gldisplaymanager to javafx.fxml;
exports org.leder.gldisplaymanager;
exports org.leder.gldisplaymanager.gui;
opens org.leder.gldisplaymanager.gui to javafx.fxml;
uses java.sql.Driver;
}
更新：我编译了一个 IntelliJ 项目导入和 Linux 应用程序执行的最小示例，如下 -
预期结果：
java.sql.SQLNonTransientConnectionException: Socket fail to connect to host:address=(host=localhost)(port=3306)(type=primary). Verbindungsaufbau abgelehnt 实际结果：
java.sql.SQLException: No suitable driver found for jdbc:mariadb://localhost/display_manager 更新2：
pom.xml依赖如下：
<dependency>
<groupId>org.mariadb.jdbc</groupId>
<artifactId>mariadb-java-client</artifactId>
<version>3.3.3</version>
</dependency>
这是一个部分手动的、不完美的解决方案，但仍然可以执行。
(1) 打开您的 https://drive.google.com/drive/folders/162vRPYNnSbE0xddLoNGQ2oPTWUtSmSlt?usp=sharing（intelliJ_project 和 Linux_app）
(2) 下载 mariadb.zip
(3) 解压 mariadb.zip
(4)
cd mariadb(5)
mvn package生成输出 -> target/mariadb-1.0-SNAPSHOT.jar
(6)
mvn dependency:copy-dependencies -DoutputDirectory=target/libsgenerate -> target/libs 包含该目录下的所有jar文件
(7)
mvn javafx:jlink生成->目标/应用程序目录
(8)执行命令
cp target/mariadb-1.0-SNAPSHOT.jar target/app/lib/cp target/libs/*.jar target/app/lib/cp target/app/bin/app target/app/bin/app.org(9)编辑target/app/bin/app文件

(1) 应用程序内容是通过Gradle插件修改的
The Badass Runtime Plugin(2) 这个答案还不够好。 如果您已经知道如何执行手动步骤，您可以将上述内容重写为自动化的 Maven 配置。
