I'm trying to get NIOS SBT installed with Quartus 19.2. Bug ID 1409124444 kbd article mentions that with Quartus 19.1 and presumably onwards, NIOS II EDS isn't included with Quartus for some reason.
So I followed the instructions, but the version hosted on the Eclipse website 404s for all versions. I need the 64-bit Linux files.
I tried using the plugins file in conjunction with a newer version of Eclipse (Photon from 2018) but that causes a multitude of issues due to version mismatches in config files and presumably core differences in the design of the software.
Is there a mirror outside of the official Eclipse site where I can acquire the download?
