Java mvn exec performance?

The exec plugin runs programs inside the same JVM maven is running in. Assuming you use the same JVM flavor for both maven and your java command line, there shouldn't be a big different if that's all you do .

Well, since mvn exec:java ... would run in the same JVM as Maven, there wouldn't be much of a difference, except for the fact the running java my. MyClass would always be a tad quicker, as Maven will execute some operations before actually running the class.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
