Import items from MyEclipse to eclipse error Com.genuitec.runtime.generic.javais not defined.

1 class path problems

In Java development, most developers use the IDE MyEclipse and Eclipse, and the easiest problem to import from MyEclipse to eclipse is the classpath problem. Because MyEclipse basically integrates all of the class libraries, similar to the class libraries we built under Eclipse, all the import-related class libraries are references, so the first thing to do when importing items from MyEclipse to Eclipse is "project", "right-click" "Build Path", "Configure Build Path", "libraries", modifying the class library path

Open the/.settings/org.eclipse.wst.common.project.facet.core.xml file under the project directory
