I'm trying to start the dl4j examples in IntelliJ using the 1.8 Java 64x JDK.
I've followed the instructions exactly like in description
Now the last step doesn't work. While starting i get hundreds of exception like:
Error:(3,35) java:package org.deeplearning4j.berkeley does not exist
or
Error:(19,38) java:cannot find symbol symbol: class BaseLayer
So I guess the problem has something to do with the import of the package. I need to add that I'm new to IntelliJ. Do i need to consider something special about it? Is it possible that I need to rebuild the pom.xml for Maven because of using Java 8?
Thanks for any ideas!
P.s. maven clean install (Version: 3.16.0-4-amd64) throws some exceptions:

It might be a little late, but I had the same error...
For me it was that the JAVA_HOME variable was set to the JRE and not to the JDK. so set the JAVA_HOME variable to something like this: C:\Program Files\Java\jdk1.8.0_112 (of course the version am vary)
Otherwise there is the Link for Help 1: http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException There are also some common examples why it might fail...
