I am using M2Eclipse (0.10.0, Maven 3)in projects. I can add Maven dependency using m2eclipse. But dependency jars couldn't be downloaded. Instead, it created a file in each local repo folder named [JAR_Name].jar.lastupdate. The content of this file is some thing like : http\://[REPO_URL]/central/=1276221188566 Even using Maven 3 command line. Jars couldn't be downloaded. Any idea about how could this happen?
