Subject [jira] [Commented] (MDEPLOY-221) deploy generates wrong timestamps in maven-metadata.xml
Date Thu, 08 Jun 2017 22:51:18 GMT

    [ https://issues.apache.org/jira/browse/MDEPLOY-221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16043573#comment-16043573
] 

Guillaume Boué commented on MDEPLOY-221:
----------------------------------------

[~vvandens] I reproduced the issue clearly when building [Jspresso|https://github.com/jspresso/jspresso-ce],
thanks for this example. The issue actually stems from the use of {{flexmojos-maven-plugin}}
as an extension. The consequence is that metadatas are getting downloaded / uploaded twice,
and the correct metadata of the first time is getting overwritten by the second time, sometimes
built a second after. You can actually notice the duplicate download / upload in OP's initial
output

This is indeed a Maven Core 3.5.0 issue, and does not come from the Deploy plugin. I will
create a MNG issue with a possible fix.

> Some of the timestamps in that file have second 27, while others have second 28. The
uploaded files all have 27 in their file names, therefore the information in the metadata
file is wrong, and the files cannot be downloaded.
> We didn't notice this problem until three days ago, when we updated from Maven 3.3.9
to 3.5.0. Both of these Maven versions use version 2.8.2 of the plugin.
> Running {{mvn install}} alone does not have this problem since no version timestamps
are used there; the version numbers are just {{31.0.0-SNAPSHOT}} there.
