Can't create a Parsley Project [message #1690611]

When attempting to create a Emf Parsley Dsl based Project the project wizard I get a Problem Opening Wizard Dialog with the message:

The selected wizard could not be started.
org/eclipse/xtext/xtype/XtypeFactory
(java.lang.NoClassDefFoundError: org/eclipse/xtext/xtype/XtypeFactory)

Running on a brand newly installed Eclipse Modeling Tools
Version: Luna Service Release 2 (4.4.2)
Build id: 20150219-0600
Emf Parsley 0.3.0.v20150220-0847
which I installed from the Parsley update site.

Fix was to install the latest Xtext. Should n't the install not require and install it in the first place so it doesn't have to be done manually?

Hi

actually it should automatically install all the Xtext requirements;
which version of Parsley have you tried to install and which update site
have you used? Which Parsley features have you installed? We have
recently released the first official version 0.3.0 and it should install
all the requirements.

cheers

Update Site: Originally used the ".../emf-parsley/updates/0.3" noticed a problem adding the project. Then I tried:
Parsley All updates ".../emf-parsley/updates/" still had a problem so I manually provisioned the Xtext and after that I could add a new parsley project.

I have not tried it with a new installation of Eclipse since I encountered it to reproduce the problem. Perhaps it was just a strange p2 anomolie??

And you previously added
http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/
as an update site as described here
https://www.eclipse.org/emf-parsley/download.html, haven't you?

Has the checkbox "Contact all update sites..." been checked?

cheers

Both sites were added per instructions:

Xtext Updates http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/ Enabled
Parsley All updates http://download.eclipse.org/emf-parsley/updates/ Enabled

Believe the checkbox was enabled, but not sure. Besides either way if the dependencies are set for the packages than it should NOT install them if it can't find the deps. Right?

Have not gone back and confirmed this issue with a new install - perhaps this was a p2 anomolie??

yes, you're right

it could have been an anomaly... I'll check that myself with a new install
