While trying to add Hibernate capabilities to my project, myeclipse fails with the following message:

— Error message —
Unable to install Hibernate nature.
Reason: error adding nature com.genuitec.eclipse.hibernate.hibernatenature to project Biblio.
Details: Resource is out of sync with the file system: /Biblio/.project.
— End of error message —

This problem maybe related to the fact that initial project layout and classpath was created with Maven 2.0 (not using eclipse plugin, just from the command line), so all the dependencies for Hibernate and everything else were resolved before I tryied to add a Hibernate nature with MyEclipse.

While going through dialog “Adding Hibernate capabilities”, I tryied to exclude or include MyEclips libraries for the classpath in the first window, define or skip defenition for SessionFactory package, all with the the end result.

Here is details of my system:

I have two plugins, aside from MyEclipse:
1. Maven 2.0 plugin – however, I didn’t use it.
2. Subversion plugin.

It seems there is something in .project file which Maven 2 creates for eclipse project, which is incompatible with MyEclipse.
Here is my .project file

Try right-click your project and doing refresh. Is seems that your .project is out of sync and refreshing should bring it back in sync.

[Sergey Malov]

No, this is not the solution.
These two lines in my .project file confict with myeclipse when it tries to add Hibernate support:

<nature>org.eclipse.jem.workbench.JavaEMFNature</nature>
<nature>org.eclipse.wst.common.modulecore.ModuleCoreNature</nature>

These lines are added by Maven 2 when I created eclipse prject from maven project. Since according to eclipse:eclipse Maven plugin web site, these two lines are optional, I removed them and all went ok.

Question is, why myeclipse fails when these lines are present?

Regards,
Sergey

[Greg]

Not for sure why it would fail with these natures because it doesn’t care what other natures have been added. But I’m glad you got it working.
