Issue: Maven-dependency-plugin (Goals "Copy-dependencies", "unpack") is not supported by M2E.
This time, we've replaced 64 new notebooks with the latest Eclipse Indigo version (v3.7), Maven 3.04, and m2e plugins. From the SVN server to check down the project being developed, there is a red fork, pom.xml error is as follows: Maven-dependency-plugin (goals "Copy-dependencies", "unpack") is not Supported by M2E. Searching for solutions on the Internet, most people propose to add maven-dependency-plugin configuration in Pom.xml. But why is it possible before it is installed? So the problem should be focused on the development environment, and it is certain that the M2E plugin is not installed.
As I expected, the M2E plugin was officially relocated from Sonatype to the eclipse community, but it has also been upgraded on the official website, in fact the older version of the eclipse community that was downloaded. See M2E Two installation address:
http://download.eclipse.org/technology/m2e/releases/
Http://m2eclipse.sonatype.org/sites/m2e
The former is the eclipse community, the latter is the official website, to the author to solve the error, the version has a gap. Just I used the former, uninstall after the latest version of the latter is good.
