title: Execution failed for task ':kotlin-source:compileKotlin'
body: <p>I tried to run the cordapp-example from the command prompt. But when I input the "gradlew.bat deployNodes" command, I got the error as below.</p>

  <p>I had done the "keytool -importcert" command to import the certificate of jolokia-war into java cacerts, but the error was still there.</p>
  
  <p>Does anyone know how to solve the problem?</p>
