[orion-releng] Changes to Orion client build (Action required, maybe)

[Mark Macdonald <mamacdon@xxxxxxxxx>]

I just released changes to speed up the org.eclipse.orion.client build. It now runs minification using Node.js + Uglify rather than Rhino + Google Closure. This makes it much faster: the minification is around 3x faster by my estimate. As a bonus, the source maps generated by Uglify seem more reliable than Closure's.

But, every rose has its thorn, or something: if you're running an unusual OS -- that is, something other than Linux/Windows/OS X -- the build might fail to find a compatible Node binary. If this happens, you can configure the build to use Nashorn instead, which is slightly slower. Rhino is no longer supported.

So to sum up:

• ​​
  If you build
  ​orion-client on a platform
  ​for which Node.js binaries are not available,
• then you must run the build under Java 8+
  ​,
  
• and
  ​you must set one of the following flags when building:
  
    mvn -DskipNodejs
  or
    mvn -P '!nodejs'
  
  These will skip installation of Node.js and use jjs instead.
  

I documented these changes on the Releng Builds page.
