faces-config.xml graphic editor not works

In a jsf project with structure like this:

--src/main/java
--src/main/resources

I've faces-config.xml in /META-INF directory, placed under src/main/resources. My pom.xml include this configuration:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-eclipse-plugin</artifactId>
	<configuration>
		<wtpversion>2.0</wtpversion>
		<additionalProjectFacets>
			<jst.web>2.5</jst.web>
			<jst.jsf>1.2</jst.jsf>
			<jst.ejb>3.0</jst.ejb>
		</additionalProjectFacets>
	</configuration>
</plugin>

After mvn eclipse:eclipse i've under .project directory, the file org.eclipse.wst.common.component:

<project-modules id="moduleCoreId" project-version="2.0">
  <wb-module deploy-name="eos-components">
    <wb-resource deploy-path="/" source-path="src/main/java"/>
    <wb-resource deploy-path="/" source-path="src/main/resources"/>
  </wb-module>
</project-modules>

Now, if i open faces-config.xml with graphic editor, i've some error in eclipse log, and i can't use it, neither i can save the file! (in the log: !MESSAGE Resource '/eos-components/src/main/java/eos-components/src/main/resources' does not exist.)

But if I manually invert the order of wb-resources, all works fine!

<wb-resource deploy-path="/" source-path="src/main/resources"/>
<wb-resource deploy-path="/" source-path="src/main/java"/>
