Maven Dependency Download fails

Upon using the maven dependency details provided in sikulix (http://sikulix.com/quickstart/) website, the installation fails..
The error I see is, dependency resolution exception.

My pom.xml is file like below:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 <modelVersion>4.0.0</modelVersion>
 <groupId>MySel20Proj</groupId>
 <artifactId>MySel20Proj</artifactId>
 <version>1.0</version>
 <dependencies>
  <dependency>
   <groupId>org.seleniumhq.selenium</groupId>
   <artifactId>selenium-server</artifactId>
   <version>2.53.0</version>
  </dependency>
  <dependency>
   <groupId>com.sikulix</groupId>
   <artifactId>sikulixapi</artifactId>
   <version>1.1.0</version>
  </dependency>
 </dependencies>
</project>

It works fine for the dependency details(sikuli 1.2.0) given mvn website - https://mvnrepository.com/artifact/org.sikuli/sikuli-api.

Can you please help?
