James Wing commented on NIFI-2115:
----------------------------------
I tested building from a source zip. There are two concerns -- building
outside a Git repo that provides commit and branch info, and building without
Git tools installed at all. The plugin included in this PR,
buildnumber-maven-plugin, has a {{revisionOnScmFailure}} property configured to
"unknown source" when there is no git environment. The plugin will log
warnings like the following:
{code}
[WARNING] Cannot get the revision information from the scm repository,
proceeding with revision of unknown source :
Exception while executing SCM command.
[INFO] Storing buildNumber: unknown source at timestamp: 1466883469071
[WARNING] Cannot get the branch information from the git repository:
Error while executing command.
{code}
For a source build, the timestamp is the only useful addition, and the data
captured looks like this (as seen in nifi.properties):
{code}
nifi.build.number=unknown source
nifi.build.branch=UNKNOWN_BRANCH
nifi.build.timestamp=2016-06-25T20:16:40Z
{code}
I admit it's not elegant, but it does not break. Testing is complicated by the
requirement for Git to support Bower in nifi-web-ui (see NIFI-1846).
> Enhanced About Box Version Information

> Key: NIFI-2115
> URL: https://issues.apache.org/jira/browse/NIFI-2115
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core UI, Tools and Build
> Affects Versions: 1.0.0
> Reporter: James Wing
> Assignee: James Wing
> Priority: Minor
>
> The UI's About dialog and underlying API provide the version of NiFi, like
> "0.7.0-SNAPSHOT". For many bug reports and troubleshooting requests, this is
> not very precise, especially around rapidly changing code or
> platform-dependent behavior. It would help if NiFi captured and displayed
> additional information:
> * NiFi build commit hash
> * NiFi build branch
> * NiFi build date/time
> * Java Version
> * Java Vendor (Oracle, OpenJDK)
> * OS
> Then a simple copy/paste from the about box would provide very specific
> information about a particular NiFi installation and which code it was
> derived from.
