Answer 1

You get this error because the MariaDB JDBC driver has a dependency on the Waffle JNA (Java Native Access) library.

To get rid of this error you need add the waffle.jna library to your module-info.java file:

requires waffle.jna

Or include the library to your pom.xml if you are using Maven

<dependency>
    <groupId>com.github.waffle</groupId>
    <artifactId>waffle-jna</artifactId>
    <version>3.2.0</version>
</dependency>

If you're using Gradle add it to your build.gradle

dependencies {
  implementation group: 'com.github.waffle', name: 'waffle-jna', version: '3.2.0'
}

If you're using java eclipse u can add it to the .classpath file

<classpathentry kind="lib" path="/path/to/waffle-jna-3.2.0.jar"/>

You can download the jar file here
