             Summary: nbbuild : DownloadBinaries task:  5 secs connect time is not enough
                 Key: NETBEANS-5478
                 URL: https://issues.apache.org/jira/browse/NETBEANS-5478
             Project: NetBeans
          Issue Type: Bug
            Reporter: Lars Bruun-Hansen
            Assignee: Lars Bruun-Hansen


h3. *nbbuild*

When building NetBeans the {{DownloadBinaries}} Ant task is executed. (this task downloads prerequisite artifacts from either Central Maven or {{https://netbeans.osuosl.org/binaries}})

However, via the {{ConfigureProxy}} class it implicitly uses a hard-coded connect timeout of 5 seconds. This would seem enough for the general case, but simply isn't enough for virtualized environments, such as GitHub Actions runners. Such environments typically incur a "first touch" penalty on outbound network connections, meaning that the first outbound connection to internet may require more connect time than 5 seconds. (after this it is of course fast). 

As a result, I see intermittent failures when the build is executed on GitHub Actions runners. Possibly someone else have seen the problem on other CI systems?

The failures have been hard to track down because both {{DownloadBinaries}} and {{ConfigureProxy}} are swallowing exceptions (not cool!). 

I'll create a PR. I'll make the connect timeout overridable via a property, but leave the default as-is for those who have become accustomed to the current fail-fast behavior.
