No repository found at http://eclipse.svnkit.com/1.10.x

Trying to build local repository using p2:mirror which will be later used to build the product.

Using antRunner to build repository but getting error:

\eclipsec.exe -application org.eclipse.ant.core.antRunner -buildfile platform-builder.xml -Drepository=drep -Dsrc_repository=dsrc
Buildfile: platform-builder.xml

create:
