Hi,

I am trying to build OpenCV via

   OpenCV-4.2.0-fosscuda-2019b-Python-3.7.4.eb

This depends on

   ant/1.10.7-Java-11

which throws the error

   ERROR: Build of
   
/trinity/shared/easybuild/software/EasyBuild/4.2.1/easybuild/easyconfigs/a/ant/ant-1.10.7-Java-11.eb

   either...

You could grab it from another location (http://ftp.apache-kr.org/ant/binaries/ for example).

The checksum we have should ensure you're getting the right thing.

because the download target has disappeared:

   https://apache.mirrors.cu.be/ant/binaries/

   Index of /ant/binaries/

What's the best way to proceed here?  Just tweak the dependency in the
OpenCV EC, or can the Belgian Apache mirror people be persuaded to
reinstate version 1.10.7?

We should reach out the the Ant maintainers and ask them to archive old versions rather than removing them...

Kenneth
