Hello

I observed the following error after migration from 2.11 to 2.12 version of XText framework

The type org.eclipse.xtext.IGrammarAccess cannot be resolved. It is indirectly referenced from required .class files	PSLRuntimeModule.java	/com.psl.atom.parent/com.psl.atom/src/com/psl/atom	line 1	Java Problem

For migration I created new project and I use maven as primary builder. I use Neon version of eclipse.
The required interface is located in plugin org.eclipse.xtext.
I've import new project to eclipse as maven project.
After importing I see the parent project and all my plugin on the first level
Also parent project contains all my plugin one more. This problem is observed on parent project.

maybe your workspace is broken. did you try another one?
in the project in eclipse a maven or a plugin project?
is org.eclipse.xtext on the path
?

What is correct way for importing

Should I import project as maven project?

or

Should I import project as existing eclipse project?

do you mean maven maven or tycho ?
in both cases importing as maven projects should work.
how does the package explorer look like?

this parent project makes no sense. it should not have any source folders at all.
maybe you have a broken classpath file checked in

I tried to create new empty project with xtext wizard. The wizard created .project file and pom.xml in parent folder, but did not create .classpath file. You wrote that .project file should not exists. May be you mean .classpath file should not exists?

in my parent folder there was .classpath file that was generated by EMF while it created code of new model for my project due to an error in configuration. I removed this file. Problem is not observed
