Error building Simplesthelloworld w/ Maven & Eclipse

[scottymac]

I am a newbie and having trouble building the simplesthelloworld portlet example that came with the GateIn src.

I am trying to compile in Eclipse in Windows.  I imported the project and moving down the tree to folder  'exo.portal.parent -> examples -> portlets -> simplesthelloworld'  When I right click on that folder and select 'Run as' -> Maven Build, I get the following error:

[INFO] Scanning for projects...

[ERROR] The build could not read 1 project -> [Help 1]

I tried a 'Maven clean' and same thing.  I also tried updating my settings.xml file from http://community.jboss.org/wiki/MavenSettingsExample-Developers, same thing. 

Please help with any ideas?

Which version of maven are you using? Have you tried with 2.1.1 ? I believe somethings changed in maven 3 with regards to the parent pom location...

[scottymac]

I am using Maven 3.0.3 (3.6.2  in eclipse details)...I will try and use the version you suggested.  Thanks.

Thanks Matt. It worked using the 2.2.1 version through the command line.  Is there a Eclipse plugin of Maven for version 2.2.1 (currently I've only found 3.0.2 which doesn't build)?  Thanks again!

you can tell the eclipse maven pluging to use a maven install on your system instead of using an embedded version. Just point the plugin to the 2.1.1 version you just installed and it should work.

Got it to work.  Thanks Matt for pointing me in the right direction...

If anyone is interested, for eclipse to use Maven 2.1.1 instead of the embedded plugin (which doesn't build GateIn), go to Window -> Preferences and add the path of the Maven 2.2.1 install to 'Installations'.  Also, when building ('Run As -> Maven Build'), select the Maven runtime for the external install.
