             Summary: Migrating from 3.4 to 3.5.1, a mvn site run now ask me for  'META-INF/maven/site.vm'
                 Key: MSITE-786
                 URL: https://issues.apache.org/jira/browse/MSITE-786
             Project: Maven Site Plugin
          Issue Type: Bug
    Affects Versions: 3.5.1
         Environment: Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0

When I switched from 3.4 to 3.5.1, running {{mvn site}} now spits errors like :

{noformat}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.5.1:site (default-site) on project api-parent: Could not find the site decoration template 'META-INF/maven/site.vm': Encountered "1.0" at META-INF/maven/site.vm"
{noformat}

Ok, seems like it's a new requirement, so I copied the one provided on https://svn.apache.org/repos/asf/maven/doxia/doxia-sitetools/trunk/doxia-site-renderer/src/main/resources/org/apache/maven/doxia/siterenderer/resources/default-site.vm, as proposed by https://maven.apache.org/plugins/maven-site-plugin/examples/creatingskins.html.

The thing is that I would have expected this file to be optionnal (everything works fine with 3.4).

But it's not enough : as the {{default-site-macros.vm}} has been separated from the {{site.vm}} file, we get an error because it's missing. There is no place on the maven-site site that tells the user where to find this file (I had to fetch it from the svn repo...).

Once that was done (copying the {{default-site-macros.vm}} in the root directory of my project), I ran {{mvn site}} once more and I get an error :

{noformat}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.5.1:site (default-site) on project api-i18n: Template file '/Users/elecharny/apacheds/trunks/shared/target/checkout/maven-site.vm' does not exist -> [Help 1]
{noformat}

actually, {{api-i18n}} is a subproject - I have 50 of them -. And the problem is that the so called 'missing template' actually exists ! :

{noformat}
localhost:checkout elecharny$ ll /Users/elecharny/apacheds/trunks/shared/target/checkout/maven-site.vm
-rw-r--r--  1 elecharny  staff  3466 Oct 26 10:56 /Users/elecharny/apacheds/trunks/shared/target/checkout/maven-site.vm
{noformat}

All in all, the only solution I have at the moment is to rollback to {{3.4}}. The ideal fix would be to have the default templates to be embedded into the plugin, and not required to be present on disk...
