> Jira report throws NPE when the resolution field is missing the "name"
> attribute
> --------------------------------------------------------------------------------
>
> Key: MCHANGES-413
> URL: https://issues.apache.org/jira/browse/MCHANGES-413
> Project: Maven Changes Plugin
> Issue Type: Bug
> Components: jira
> Affects Versions: 2.12.1
> Reporter: Alex Herbert
> Priority: Trivial
>
> The `jira-report` goal throws a NullPointerException when the resolution
> JsonNode has no "name" attribute.
> At Commons BCEL we had some tickets that were created from external issues.
> The priority field was set to an enum in [P0, P1, P2, P3, P4, P5]. See for
> example [BCEL-4|https://issues.apache.org/jira/projects/BCEL/issues/BCEL-4].
> This field did not use the standard [Major, Minor, etc] and may have been a
> custom field. (The details of how these tickets were created is unknown.) The
> "standard" priority field was missing and the data downloaded by the
> \{{RestJiraDownloader}} had no "name" attribute for this node. Thus the NPE
> from this line:
> {code:java}
> // Note: val is not null here
> issue.setPriority( val.get( "name" ).asText() );{code}
> Patching the latest maven-changes-plugin to print all these offending tickets
> allowed them to be identified and corrected by adding a "standard" priority.
> In the example mentioned (BCEL-4) there are still two priority fields in the
> ticket.
> Note that when the missing priority was ignored the Jira report completed
> successfully.
> The solution is either:
> * Patch the RestJiraDownloader to be robust to this field missing the
> expected data
> * Label as not-a-bug because this field is mandatory and BCEL has somehow
> created invalid Jira tickets in the past
