Nikolay Rybak commented on MSITE-617:
-------------------------------------
Haven't had a change to really work on minimal example for quite some time, but
finally here it is: https://github.com/GreyTeardrop/maven-site-plugin-issue
Setup: parent project has {{<distributionManagement>}} section that refers to
variable {{nexus.url}} that comes from {{settings.xml}}. If built via reactor,
everything works fine. However, if parent and child are built separately (in
reality they have different lifecycles and live in different repositories) then
{{site:stage}} and {{site:deploy}} for child project break.
Steps to reproduce:
# {{cd parent; mvn -gs ../settings.xml install}}
# {{cd ../child; mvn -gs ../settings.xml verify site}}
# {{mvn -gs ../settings.xml site:deploy}}
{noformat}
$ mvn -gs ../settings.xml site:deploy

{noformat}
If Site plugin version is changed to 3.0 beta 3 (using Maven 3.0.4) then
{{site:deploy}} and {{site:stage}} work just fine. As far as I understand, as
of version 3.0 Site plugin relativizes URLs based on top-level parent site's
URL, and seems not to expand variables in {{distributionManagement}} section.
> Variable substitution in the site url doesn't work
> --------------------------------------------------
>
> Key: MSITE-617
> URL: https://jira.codehaus.org/browse/MSITE-617
> Project: Maven Site Plugin
> Issue Type: Bug
> Components: site:deploy
> Affects Versions: 2.3
> Environment: Windows 7 and RHEL6
> Reporter: Claus Nielsen
>
> {{site:deploy}} fails because variable substitution in the site url no longer
> works (it did in version 2.2).
> The distributionManagement section in out POM looks something like this:
> {code:xml}
> <distributionManagement>
> <site>
> <id>sites</id>
> <name>Project Website</name>
>
> <url>scp://server/sites/${project.artifactId}/${project.version}</url>
> </site>
> </distributionManagement>
> {code}
> Copying the site to the above mentioned url fails with this message:
> {noformat}
> [INFO] Error uploading site
> Embedded error: Error performing commands for file transfer
> Exit code: 1 - bash:
> /sites/${project.artifactId}/${project.version}/../../id-of-the-artifact/0.2.8-SNAPSHOT:
> bad substitution
> {noformat}
> Ie. the substitutiuon variables have not been substituted, instead the
> property values have been appended to the url along with a few dots and
> dashes.
