Hi,
wishing to output some RDF to JSON-LD, I changed the dependency in my project
to:
<dependency>
<groupId>org.apache.jena</groupId>
<artifactId>apache-jena-libs</artifactId>
<type>pom</type>
<version>2.11.2-SNAPSHOT</version>
</dependency>
where I had:
<dependency>
<groupId>org.apache.jena</groupId>
<artifactId>jena-arq</artifactId>
<version>2.11.0</version>
</dependency>
I also added the following repository to my pom.xml:
<repository>
<id>apache-repo-snapshots</id>
<url>https://repository.apache.org/content/repositories/snapshots/</url>
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
I get an exception when trying to output to JSON-LD:
java.lang.ClassNotFoundException:

Here's the output of "mvn dependency:tree"
