 An API incompatibility was encountered while executing 
com.github.github:downloads-maven-plugin:0.6:upload: java.lang.NoSuchMethodError:
 org.apache.maven.execution.MavenSession.getRepositorySession()Lorg/sonatype/aether/RepositorySystemSession;

This on ubuntu using Oracle Java8:

$  mvn -version 
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=48m; support was removed in 8.0

It would be nice if this was an easy fix as this is useful functionality.

Hi, I am having similar difficulties;

The error is simply in the maven version you are using to build the project:
Checking the maven docs
maven 3.0 public org.sonatype.aether.RepositorySystemSession getRepositorySession()
maven 3.1.0 public org.eclipse.aether.RepositorySystemSession getRepositorySession()
This issue cause is from downloads-maven-plugin the latest version is 0.6 and it is using github-maven-core version 0.5 not the latest 0.12
Ah and forget to mention :-) github/maven-plugins#41
