Slow compile/download time in Java

Technical Java
1

I’m the programming mentor for a team that is thinking of making the transition from LabView to Java. We’ve noticed that the time it takes to compile and deploy Java code from NetBeans onto the cRIO is really quite long, nearly four minutes–longer than deploying LabView code and much more than is typical from what I read on other CD threads. I’m hoping that someone can help us speed this process up.

Here is the output from NetBeans:

Yes, 3-4 minutes is too long for Java.

I noticed that you stored your project in a network location. How fast is it if your project is on your local drive?

3

Yes, that was the problem! The project was actually on my local drive but, for some reason, it was accessed as if on the network. After changing that, the deployment time is pretty fast.

Thanks so much for taking the time to respond.
