Unable to deploy code to cRIO

Technical Java
1

Hi! So my team recently decided that we would like to switch to Java from C++, and we are having a bit of trouble. I have some code ready to be sent the cRIO, but I cannot deploy it as I usually get two types of errors. One is that the build.xml messes up on lines 79 and 41 (will double check on that). After that error I usually cancel the build and try again and it goes through and then proceeds to get stuck on disable()… consider using your own (will update once I have the exact phrase.

Also I do have an established connection with my cRIO. I am able to ping it as well as FTP the IP address to access it. The firewall is disabled and I allowed netbeans to use an incoming and outgoing connections as it desires. I have tried this on two different laptops to no avail. Please help!

Did you reimage the cRIO for C++?

I reimaged the cRIO for Java.

build.xml contains the ANT targets that are run to build, deploy, etc. your code. Those errors may have a lot to do with your problems. If you post what the output is telling you is going wrong in build.xml it might help.

Expected version “Java;” for Language but got “C;”

This is the most glaring problem to me. I don’t know exactly but I think your controller may not actually be imaged for Java at the moment.

It is definitely imaged to Java. I imaged it twice and just checked the FRC_ImageVersion.ini file on the cRio itself and it says:

Thank you for all of your help, turns out it was the computer!
