In some Eclipse packages, like STS or Eclipse for JEE Developers, the Terminal is already installed in your IDE. If not, you can install the TM Terminal from the Eclipse */release update site, as you can see in the image below.
To open the command prompt (shell or terminal) using the path of a project directory inside Eclipse, you just need to select the folder, and press Ctrl+Alt+T, or right-click and select Show In Local Terminal > Terminal.
Then, the terminal will open in a new view inside Eclipse.
