Cannot build rosjava (on mac) -without- ROS installed??

edit

Hi, I am trying to build rosjava (OS X 10.6.8, 32-bit, Java 1.6 without installation of ROS) based on this rosjava tutorial.

I was successfull to install it on Ubuntu 12 with Fuerte installed, everything worked.

But now, on Mac, after running:

./gradlew install

the maven repostitory on robotbrains seems to be down, i get:

    :apache_xmlrpc_common:compileJava
Checksum missing at http://robotbrains.hideho.org/nexus/content/groups/ros-public/org/apache/commons/com.springsource.org.apache.commons.httpclient/3.1.0/com.springsource.org.apache.commons.httpclient-3.1.0.pom.sha1 due to: Connection to http://robotbrains.hideho.org refused

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':apache_xmlrpc_common:compile'.
> Could not resolve group:org.apache.commons, module:com.springsource.org.apache.commons.httpclient, version:3.1.0.

I found this solution but it causes these further errors:

...

(and 22 similar ones)

So, this means that on this maven repository are some old libraries, or rosjava is not that standalone and needs ROS installation on a computer too? :(

(Unfortunately, I cannot upgrade Java to newer version, because it seems that 1.7 is not supported for 32-bit systems)

Thank you very much for help.
