Christian, please mind the link to the snapshot: https://repository.apache.org/service/local/repositories/snapshots/content/org/apache/maven/apache-maven/3.2.2-SNAPSHOT/apache-maven-3.2.2-20140427.155130-23-bin.tar.gz

If you confirm that this has been fixed by my patch, I will commit and it will be included
in 3.2.2.

Regarding measuring times: {{time mvn ...}}

> I downloaded the source tar.gz and found that indeed in line 155 of ExecutionEventLogger.java
we have 
> {code}
> 154:                String buildTimeDuration = formatDuration( buildSummary.getTime()
); 
> 155:                buffer.append( chars( ' ', BUILD_TIME_DURATION_LENGTH - buildTimeDuration.length()
) );
> {code}
> where
> {code}
> 47:    private static final int BUILD_TIME_DURATION_LENGTH = 9;
> {code}
> However, in {{formatDuration}}, from {{CLIReportingUtils.java}} , it seems that the generated
strings can well exceed this length:
> {code}
> 177:            format = "%d d %02d:%02d h";
> {code}
> This has, as far as I understand, at least 6 characters, if we add two for minutes and
minimum one for hour and one for day, this will already exceed the BUILD_TIME:DURATION_LENGTH.
This seems an obvious bug to me.
> However our build times are usually less than one hour, so there must be some other reason
for our strange long build time duration string.
> If the bug above was fixed, we could see better what's going on.
