由于文件大小为零，因此无法连接到NetBeans发行版 [英] Unable to connect to the NetBeans Distribution because of Zero sized file
问题描述
我最近在Windows 10 PC上重新安装了Netbeans IDE，以还原一些不相关的配置.当我尝试检查新的插件以能够下载Sakila示例数据库时， 我收到此错误.
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.
我已经在无代理"和使用代理设置"上测试了连接，并且两个连接测试似乎成功结束.
I've tested the connection on both No Proxy and Use Proxy Settings, and both connection tests seem to end succesfully.
我已经允许Netbeans通过我的防火墙，但这也没有改变.
I have allowed Netbeans through my firewall, but this has changed nothing either.
我还没有接触过我的代理配置，因此它是默认设置(自动检测).无论我在Netbeans上具有什么代理配置，关闭自动检测功能都不会改变任何东西.
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.
这是我的日志文件的一部分，可能会有所帮助:

更新服务器可能现在刚刚关闭；我也无法对此进行测试.但是我的配置也可能有问题.我快疯了!! 1！
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!
推荐答案
对我有用的方法是将更新URL中的"http:"更改为"https:".
Something that worked for me was changing the "http:" to "https:" in the update urls.
I.E.更改" http://updates.netbeans .org/netbeans/updates/8.0.2/uc/final/distribution/catalog.xml.gz " 到" https://updates.netbeans .org/netbeans/updates/8.0.2/uc/final/distribution/catalog.xml.gz "
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"
不知道为什么这会使它对我不利.我正在运行Linux Mint 19.1.
No idea why that makes it work on my end. I'm running Linux Mint 19.1.
