Build problem on jenkins-ci that I cannot solve

[Alexander von Zitzewitz]

I am trying to fix our plugin build (sonargraph-integration-plugin) on jenkins-ci. It always fails during a tool installation - we install Sonargraph-Build as a tool for our tests. This is done by downloading a zip file from a URL and then unpacking it. This all runs without issues on Github, our own Jenkins and on a local machine. Now I am wondering if there are size restrictions for tool downloads on your server. Sonargraph-Build needs about 280 MB. Here is the stack trace, if fails when trying to chmod a file, that should have been in the zipfile it unpacked, but cannot find:

Solved: replaced download URL with https instead of http. leaving that here for future users, that run into the same problem
