Can you guide me Regarding this post????????
Everything in maven done through plugins.And “org.apache.maven.plugins:maven-eclipse-plugin” is not available in your repository. To solve this issue, try to point remote reopsitory( configure it in settings.xml in maven installed dir),so that maven can download required plugins from from remote repositories.
Can you message me with some hints on how you made this web site look this cool, I??d be thankful.
