body: <p>I am new to big data and hadoop, I am trying to make use of hadoopcryptoledger library to do some bitcoin graph analysis, I followed this tutorial <a href="https://github.com/ZuInnoTe/hadoopcryptoledger/wiki/Using-Spark-Scala-Graphx-to-analyze-the-Bitcoin-transaction-graph" rel="noreferrer">Using spark-scala-graphx to analyze Bitcoin transaction graph</a></p>
  
  <p>While executing the command </p>
  
  <pre><code>sbt clean assembly test it:test 
  </code></pre>
  
  <p>I ran into an issue: </p>
  
  <pre><code>/home/jnikhil/hadoopcryptoledger/examples/scala-spark-graphx-    
  bitcointransaction/build.sbt:30: error: not found: value assemblyJarName
  assemblyJarName in assembly := "example-hcl-spark-scala-graphx-bitcointransaction.jar"
