mvnsh

• Pre-loaded shell environment• Speeds up build times• Based on Maven 3• Therefore can work with Maven 2 projects• History• Color Coded• Alias• Tab completion• Growl support

mvnsh

Jason van Zyl

“If you use mvnsh and find problems the turn around time for fixes is usually a day or two. Maven 3.x is better then any version of Maven 2.x and the ITs we have for Maven are in an independent project. That's mean we run the same body of tests across multiple versions of Maven and Maven 3.x passes far more then Maven 2.x. Maven 3.x just gets fixed faster. You would honestly be better off using the Maven Shell.”

Maven’s not perfect, but not many projects are. Pulling wisdom from multiple places can

only improve the end solution.
