And I got test errors (not compiling issues):

Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test (default-test) on project kucoin-java-sdk: There are test failures.

Please refer to /home/emilio/NetBeansProjects/kucoin-java-sdk/target/surefire-reports for the individual test results. -> [Help 1]
