您必须右键单击该项目，然后选择配置→转换为Maven项目

I am in Eclipse Indigo and I have installed m2eclipse plugin. I saw in Eclipse Helios there is an option Maven in the right click menu, when I clicked on a Project, but this option is not present now.

I have installed Maven from both of the marketplace and also from adding site in Install new software option in Eclipse(Help->Install New Software).

What I am doing wrong.

This question was asked before in SO, but I tried the solution provided there.

Is this option is really not present? What I want is to enable Maven Dependency Management of a Dynamic Web Project of Eclipse.

You have to do a right click on the project, then choose Configure → Convert to Maven project
