A4E for Eclipse Modeling Indigo (from marketplace)

[GoogleCodeExporter]

Hi,

I tried to install A4E from the Eclipse Modeling Indigo marketplace for linux 
64bits and the following occurs:

Creating an alloy model (File->new->other->alloy->alloy 4 model):

The selected wizard could not be started.
Plug-in fr.univartois.cril.xtext.als.ui was unable to load class 
fr.univartois.cril.xtext.alloyplugin.ui.NewAlloyFileWizard.
An error occurred while automatically activating bundle 
fr.univartois.cril.xtext.als.ui (812).

Creating a project alloy:(File->new->other->alloy->alloy 4 project):

>> From what version of eclipse this plugin is available?

Regards,
John

Hi John,

Could you check which version of Xtext has been installed? (i.e. is it 2.0 or 
2.1)

Hi Daniel,

In Indigo: Xtext SDK 2.0.1 v201108020636

In Helios:
I installed the A4E and:

When I created a new model: File-> New-> model 4 alloy
He is not able to get the modules "util/ordering, util/integer ..."

When I created a new project: File-> New-> Project 4 alloy
It adds another project called "A4 models libreary" and so when I create a new 
model, he is able to get the modules. But there are conflicts between these 
modules, such as max and min function that exists in more than one module. 
Also, references to other names he does not recognize as totalOrder, Lookup, 
children.
So my models have errors which are caused by this.

John,

The version of Xtext is fine.

You are supposed to create a new Alloy project before creating an Alloy model.

We indeed still have an issue with some Alloy models, mainly when an identifier 
appears several times with different signatures.

It should not prevent you to write and run your own models.

I am having a similar problem in that it won't run the wizard, so I can't open 
a project.

Should I manually install?

Do you mean that you had a previous version of A4E running and updating to the 
latest version using the marketplace does not work?

If this is the case, then you need to uninstall the old version of the software 
first.

I am new to Eclipse, and I only installed it because I wanted an IDE to use 
with Alloy.  

However -- I can't get the Alloy4Eclipse to work.  The error it gives (when 
trying to run the wizard to create the project is

The selected wizard could not be started.
Plug-in fr.univartois.cril.xtext.als.ui was unable to load class 
fr.univartois.cril.xtext.alloyplugin.ui.NewAlloyProjectWizard.
An error occurred while automatically activating bundle 
fr.univartois.cril.xtext.als.ui (815).

I tried to see if clearing out Eclipse and downloading an older version would 
help, but no joy in getting past the wizard error.

If there was no previous version of A4E installed, it should work out of the 
box.

I guess you installed Eclipse Indigo SR1, right?

Which edition did you download? (Java, modeling, JEE…)
Which OS are you running? Which version of Java?

I downloaded the most current version, which I think is 3.71.   I tried the 
classic version, then I tried JEE.

I am running Windows, and I tried on two machines - the first was running 32bit 
XP and the other is running 64bit windows 7.

The issue here is that installing A4E with recent version of Xtext does not 
work because A4E was built for Xtext 1.x and that Xtext 2.x is now available, 
but not backward compatible with 1.x.

We now have a version of A4E compatible with Xtext 2.0. We expect to make a 
trial release available by the end of next week.
