Maven Artifact Dependency Misconfiguration

As described in mvn repo site for jcaptcha 1.0 http://mvnrepository.com/artifact/com.octo.captcha/jcaptcha/1.0

POM dependency:
<dependency>
<groupId>com.octo.captcha</groupId>
<artifactId>jcaptcha</artifactId>
<version>1.0</version>
</dependency>

When given dependency entry is used it throws a WARNING:
[WARNING] *** CHECKSUM FAILED - Error retrieving checksum file for com/octo/captcha/jcaptcha-api/1.0/jcaptcha-api-1.0.jar - IGNORING

and throws an ERROR about

[ERROR] BUILD ERROR
[INFO] ----------------------------- [INFO] Failed to resolve artifact.

Missing:
---------- 1) com.jhlabs:imaging:jar:01012005

I think there is a misconfiguration in maven artifact dependencies.

Is it possible to fix it?
