I had this same problem using a library that used a new codec for lucene.
In creating the jar maven was replacing the META-INF. I solved the problem
with the following configuration in pom.xml
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>
META-INF/services/org.apache.lucene.codecs.Codec </ resource>
</ transformer>
</ transformers>
</ configuration>
