Hello!

I am trying to move to myeclipse.

When I clikc to package maven project it gives me error that metamodel classes are duplicated.
Because metamodel is present in project before I package it.

When I package with maven it generates new bunch of metamodel classes which are the same as I have !

Please, help to avoid this because I am fighting this for about two days!

This is not issue of IDE but something else.

Maybe it is Maven!

What generates metamodel classes when I do 'mvn package' and how to stop it.

I think that has something to do with the plugins that are defined in the pom.xml file. Without knowing what plugins you have in pom.xml it is hard to say what the solution would be. Perhaps post the pom.xml.

Hello Peter!

Thank you for reply!

I resolved this issue already by deleting each time before packaging those metamodel classes.
I do this simply by

Then when I refresh project IDE automatically builds the same metamodel classes again!

Unfortunately I really stuck with this stupid issue:
My glassfish-web.xml is simple and is almost all copied from JavaEE-tutorial:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">

<property name="alternatedocroot_1"
value="from=/lib/* dir=C:/glassfish3/glassfish/domains/domain1/" />
</glassfish-web-app>

When deploy my war I have this error (the funny thing that it is not always, but often)
