Adding a build section to the POM:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<manifestEntries>
<Main-Class>com.mycompany.app.App</Main-Class>
<Build-Number>123</Build-Number>
</manifestEntries>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
To the POM gives me a self contained runnable jar. Progress! I’m learning.
BUT as before when I run the jar, I get the Exception: No compatible service:
org.scijava.service.SciJavaService
=================================================================
[Michaels-Retina:~/temp/deleteme/my-app] michaelellis% java -jar
target/my-app-1.0-SNAPSHOT.jar
Hello World!
Exception: No compatible service: org.scijava.service.SciJavaService
=================================================================
Still vexed!
