Eclipse x Java

Just for record:

Deployment assembly

Changing some attribute on the "Deployment Assembly" option of a Java project changes the two files below on the project on Eclipse:

<project>/.settings/org.eclipse.wst.common.component
<project>/.classpath

Facets

The same apply to changes on the "Facets" option on Eclipse:

<project>/.settings/org.eclipse.wst.common.project.facet.core.xml

See you :-)
