Hi Patrick, first of all welcome here on our list. We will do our best to assist you.
I did notice a few things: * You are using the API in version 0.6.0 but the drivers in 0.5.0 … I would strongly suggest not to mix versions * The drivers you are using are in version 0.5.0 … I would suggest to update to version 0.6.0 as the 0.7.0 or 0.8.0-SNAPSHOT version don’t have ADS support yet Are you using any form of “Fat-Jar” or shaded archive approach? Cause we have seen this behavior in these cases. The problem is that every driver has a property file in “META-INF/services” … each lists only the driver the module provides. So in case of the default settings the plugins for creating the fat jars just take one of these property files and skips the rest. You can however configure it to merge the content. For an example on this please see the examples pom.xml <!-- Build a fat jar containing all dependencies --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <executions> <execution> <id>generate-uber-jar</id> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <transformers combine.children="append"> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>${app.main.class}</mainClass> </transformer> </transformers> </configuration> </execution> </executions> </plugin> Hope that helps, if not … just come back and we’ll try to help you.
