unable to build jboss portal open source

[anj]

i have got jboss portal source from jboss cvs using wincvs option (since my eclipse cvs is blocked on firewall) .
after i import all the projects in my eclipse, it get class parth error for thirdparty, for that i understand i have to run build from the build folder,

however the build is unsuccessfull due to following error

Executing D:\jboss\jboss-portal-2.4.0-src\build\..\tools\bin\ant.bat -logger org.apache.tools.ant.NoBannerLogger
Buildfile: build.xml

createthirdparty:
[get] Getting: http://repository.jboss.com/antlr/2.7.6.ga/component-info.xml
[get] To: D:\jboss\jboss-portal-2.4.0-src\thirdparty\antlr\component-info.xml
[get] Error getting http://repository.jboss.com/antlr/2.7.6.ga/component-info.xml to D:\jboss\jboss-portal-2.4.0-src\thirdparty\antlr\component-info.xml

can anyone provide steps to build jboss portal source.
i have check out the thirdparty folder from the cvs. but have no luck on how to solve the class path errors on jboss portal source for thirdparty

could you please guide, is there something missing in my environment....

thanks

If your corporate firewall is blocking access to the source code repository, it is probably also blocking access to the third party library (Maven) repository. By the way, the source is now in Subversion at http://anonsvn.jboss.org/repos/portal/.

Could you try doing this from home (or somewhere outside the corporate firewall) and see if it works there.

You could also enter http://repository.jboss.com/antlr/2.7.6.ga/ into your browser to see if you get the directory listing, and then click on the component-info.xml file and see if that gets displayed. If you cannot do that, then you will *not* be able to download that same file from the build.
