Hey, this is an issue that multiple people here faced... (cdutz, sruehl, myself at least). Can we do anything to document that better? I guess not?

I only had used the ManifestResourceTransformer (which is included in the pom.xml in the examples-folder). The Service transformer is inherited from the project root pom.xml Works now as expected....

Every driver has a META-INF/services/org.apache.plc4x.java.api.PlcDriver file, which lists that particular driver. If you run the shade plugin without any transformer only one of these are packaged in the jar the others are omitted. That's why you have only one driver availale. In order to fix this please update your plugin configuration like we did in the examples: <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> <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>${app.main.class}</mainClass> </transformer> </transformers> <filters> <filter> <!-- These files contain signatures for classes, omit them as in shaded archives this has cause quite some problems in the past. --> <artifact>*:*</artifact> <excludes> <exclude>META-INF/*.SF</exclude> <exclude>META-INF/*.DSA</exclude> <exclude>META-INF/*.RSA</exclude> </excludes> </filter> </filters> </configuration> </execution> </executions> </plugin> Hope that helps.
