Unable to connect to the NetBeans Distribution because of Zero sized file

问题


I recently reinstalled Netbeans IDE on my Windows 10 PC in order to restore some unrelated configurations. When I tried checking for new plugins in order to be able to download the Sakila sample database, I get this error.

I've tested the connection on both No Proxy and Use Proxy Settings, and both connection tests seem to end succesfully.

I have allowed Netbeans through my firewall, but this has changed nothing either.

I haven't touched my proxy configuration, so it's on default (autodetect). Switching the autodetect off doesn't change anything, either, no matter what proxy config i have on Netbeans.

Here's part of my log file that might be helpful:

It might be that the update server is down just right now; i haven't been able to test this either. But it also might be something wrong with my configurations. I'm going crazy!!1!


回答1:


Something that worked for me was changing the "http:" to "https:" in the update urls.

I.E. Change "http://updates.netbeans.org/netbeans/updates/8.0.2/uc/final/distribution/catalog.xml.gz" to "https://updates.netbeans.org/netbeans/updates/8.0.2/uc/final/distribution/catalog.xml.gz"

No idea why that makes it work on my end. I'm running Linux Mint 19.1.
