MyEclipse importing Maven project does not download jar problem

Colleagues with MyEclipse6.5 do not know why is not using MAVEN, import Weblogic.jar will not automatically introduce the relevant jar, so upgrade to 2014, thought to import Maven project should be no problem, who knows the error:

Errors running builder ' Maven Project Builder ' on Project ' Acctmanm '.
Could not calculate build Plan:plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies Coul D not being resolved:failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5

Why is that?

But still do not, so, find Maven-resources-plugin:jar directory, lastupdated deleted, re-update Dependence,jar out, do not report this wrong.

This is the jar that Maven needs, and the other jars that the project relies on also have this error, causing maven dependence in myeclipse to get out of the way, as in the red box.

Open Build path is also a fork said can not find the jar package (for example, only a few two jar,pom in the majority of the jar is not out, and out of the two is a fork):

It is not possible to delete the update file.

Finally, found, with the Everything tool, all the lastupdated files to find out, batch delete, OK!

Note: Online (including "Maven Combat" book) Many say right-click Update Dependence, in the MyEclipse2014 m2eclipse plugin did not, because the latest plugin changed, should be:

Here it is.
