[jira] [Commented] (BUILDR-700) Buildr truncates some jar files in
my local repo if they are set to download from a specific URL
[ https://issues.apache.org/jira/browse/BUILDR-700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14051306#comment-14051306 ]
Peter Donald commented on BUILDR-700:
-------------------------------------
Add for future reference the actual bug was that buildr was truncating SNAPSHOT dependencies that had not updated since the last update and the HTTP server was returning a "HTTP Not modified" status

> {noformat}
> So it seems like buildr is truncating the file daily.
> Deleting the files and re-running buildr puts the correct files back. Any subsequent builds for that day will continue to work as per usual, then the next day, buildr will truncate the file again.
> Interestingly, I use the same approach for icu4j-charsets.jar:
> {code:ruby}
> ICU4J = [ artifact('com.ibm.icu:icu4j:jar:53.1'),
> artifact('com.ibm.icu:icu4j-charsets:jar:53.1') ]
> download artifact('com.ibm.icu:icu4j-charsets:jar:53.1') =>
> 'http://download.icu-project.org/files/icu4j/53.1/icu4j-charset-53_1.jar'
> {code}
> But the issue has *never* occurred for this jar. Fiddling the timestamps on the files makes for a reliable reproduction for SwingX, though:

> {noformat}
> So it looks like when the file has not been modified since the last download, buildr replaces the local file with a zero-length file which it was presumably using to do an atomic file download.
