{code}
It occurs not every build, but maybe every second or third.
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 whatâs going on.
