Plugin installation problems

[David Jencks <da...@yahoo.com>]

We've been seeing severe plugin installation problems in the gbuild 
build; it looks like the plugins built in (the equivalent of )new1 are 
not available for use in (the equivalent of) new4 or new5.  After 
looking at some maven plugin plugin jelly code I think this might be 
because plugin:install and plugin:install-now are interfering with each 
other and that running both will never work.

I've modified what we run in the plugins to this:

     <goal name="plugin:install" prereqs="plugin:plugin">
         <attainGoal name="plugin:install-now"/>
         <attainGoal name="plugin:repository-install"/>
         <copy file="${maven.build.dir}/${maven.final.name}.jar"
           todir="${maven.plugin.dir}" />
      </goal>


which IIUC should have the same effects as plugin:install 
plugin:install-now plugin:repository-install without the interference.  
However whether your build works after messing with plugins seems to be 
very dependent on what was there before, so please look out for and 
report problems.

thanks

plugin:install-now is the same as plugin install, but it loads into
the running Maven and updates the cache, like using a plugin
dependency. You are right that they are probably incompatible.

plugin:repository-install is only useful if you are later using it as
a dependency. Maven doesn't use the repository for plugins otherwise,
and this goal doesn't affect the cache.
