Eclipse Version: Mars.2 Release (4.5.2) Build id: 20160218-0600

Via the Marketplace, Installed XText Version: 2.9.2.v201603040440 Build id: R201603040440

clicked New-> Project-> Xtext-> Examples-> XText Simple Arithmetics Example-> Next

It listed 5 project to create:
org.eclipse.xtext.example.arithmetics
org.eclipse.xtext.example.arithmetics.ide
org.eclipse.xtext.example.arithmetics.tests
org.eclipse.xtext.example.arithmetics.ui
org.eclipse.xtext.example.arithmetics.ui.tests
clicked Finish

Created the 5 projects.
There were 2,334 errors, 9 warnings.

What was my mistake?

Hi,

this is hard to say. can you give some error messages you get? are there errors on the manifest.mf files?

there are no errors in the manifest.
many of the errors seem to be "cannot be resolved"
I will see if I can find an example with fewer errors.

what happens if you create a new project by the wizard
right click the xtext editor , run as -> generate xtext artifacts

(if it asks to download antlr answer with yes)

Just generating a generic XText project creates 27 errors.
Here are the 2 in MyDsl.xtext

Description Resource Path Location Type
Couldn't resolve reference to Grammar 'org.eclipse.xtext.common.Terminals'. MyDsl.xtext /org.xtext.example.mydsl/src/org/xtext/example/mydsl line: 1 /org.xtext.example.mydsl/src/org/xtext/example/mydsl/MyDsl.xtext Grammar Problem

ID cannot be resolved to a rule MyDsl.xtext /org.xtext.example.mydsl/src/org/xtext/example/mydsl line: 9 /org.xtext.example.mydsl/src/org/xtext/example/mydsl/MyDsl.xtext Grammar Problem

I did locate an include error in the other test case, so there may be multiple problems

hmmm

looks like the installation did not work as well.
can you retry using http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/

I created the basic XText project with the 27 errors. Where is the xtext editor? Nothing has been generated or built.

EMF Core and MDT XSD
EMF Xcore
MWE
Xtend
Xtext

I now see that the XText install instructions suggest using: http://download.itemis.de/updates/

Is that in error, or is it the same thing?

I assume that the problem is that EMF, MWE, XTend and XText all need to be installed, and that installation via the Eclipse Marketplace does not insure that.

This looks perfectly fine. Are you sure you have build automatically on and called project clean build once

thanks again.
by the way, I'm interested in the source for the generated editor - i couldn't seem to find it.
I found the activator and the editor class but it could not be browsed. Apparently it is a class and not Java.
Are there parts of XText that are proprietary or is all the source available?

Depending on the feature of xtext you installed there should be installed
source bundles as well and thus you should see sources for the xtext editor
class
