Issue with OrekitException in Orekit Attitude Tutorial

1

Apologies, I’m very new to Java so this question may be quite basic. I’m currently running Orekit 12.2 with Jave openjdk 17.0.14, Maven 3.9.9. When trying out the tutorials (attitude->EarthObservation) I get an error that the class org/orekit/errors/OrekitException cannot be found. I’ve verified that it’s in the Maven repository for Orekit 12.2. I don’t get the error during mvn package or mvn install but it pops up when I run the tutorial (java -cp .\target\orekit-tutorials-12.2.jar org.orekit.tutorials.attitude.EarthObservation). Does anyone have an idea of what could be causing this?

Found the issue. If anyone runs into a similar problem, I needed to “shade” the library code into my output JAR file using the built-in maven shade plugin. I included this into the default pom.xml file:

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.5.2</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
