> api's AbstractConsumer ignores Locale when using a custom dateFormatter
> -----------------------------------------------------------------------
>
> Key: SCM-744
> URL: https://issues.apache.org/jira/browse/SCM-744
> Project: Maven SCM (Moved to GitHub Issues)
> Issue Type: Bug
> Components: maven-scm-api
> Affects Versions: 1.8.1
> Reporter: MatÃas Albanesi
> Priority: Minor
>
> Class org.apache.maven.scm.util.AbstractConsumer contains a method:
> protected Date parseDate( String date, String userPattern, String
> defaultPattern, Locale locale )
> Which ignores the specified locale if there is a userPattern specified.
> Current implementation is:
> if ( StringUtils.isNotEmpty( userPattern ) )
> {
> format = new SimpleDateFormat( userPattern );
> patternUsed = userPattern;
> }
> When the date parsing fails it misleadingly displays a message indicating
> that it did make use of the Locale but clearly it did not:
> [ERROR] skip ParseException: Unparseable date: "Mon Oct 21 18:14:36 2013
> -0300" during parsing date Mon Oct 21 18:14:36 2013 -0300 with pattern EEE
> MMM dd HH:mm:ss yyyy Z with Locale en
> java.text.ParseException: Unparseable date: "Mon Oct 21 18:14:36 2013 -0300"
> at java.text.DateFormat.parse(DateFormat.java:337)
> at
> org.apache.maven.scm.util.AbstractConsumer.parseDate(AbstractConsumer.java:112)
> at
> org.apache.maven.scm.provider.hg.command.changelog.HgChangeLogConsumer.doConsume(HgChangeLogConsumer.java:196)

> at
> org.codehaus.plexus.util.cli.StreamPumper.consumeLine(StreamPumper.java:195)
> The issue happens because my environment has user.language=es,
> user.country=AR. Even passing these parameters in the command line does not
> help:
> mvn clean changelog:changelog -Duser.language=en -Duser.country=US
> fails the same way.
> How this was tested:
> - Mercurial repository
> - using maven-changelog-plugin (specifying system parameters here does not
> help either)
