-------------------------------------------
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.
