I am trying to build a single-jar Java utility. In this previous SO post, someone recommended using the onejar-maven-plugin plugin. I have tried it, but the problem I am encountering is that the plugin (1.4.4) is creates a new artifact with a one-jar.jar extension. Consequently, I end up with 2 jars in my target folder and when I try to install and/or deploy, it deploys the original jar (not the one-jar).
I have run the one-jar.jar artifact from the target folder and it works exactly as expected, so I am quite content with that. However, if I cannot deploy it properly using standard mvn deploy
command syntax, the plugin doesn't really perform as expected or as required.
Is there a way to properly structure the pom configuration to avoid this issue?
My current pom reads:
<plugin>
<groupId>com.jolira</groupId>
<artifactId>onejar-maven-plugin</artifactId>
<version>1.4.4</version>
<executions>
<execution>
<configuration>
<mainClass>com.nbfg.cws.cs.lendingsimulationservice.Client</mainClass>
<onejarVersion>0.97</onejarVersion>
<attachToBuild>true</attachToBuild>
</configuration>
<goals>
<goal>one-jar</goal>
</goals>
</execution>
</executions>
</plugin>
