Hi, I am downloading FitSDK 16.40, and running Fitgen.exe on Windows 7 64bits, and Java generation code is always failing at 42% with the following message:

Errors present in Java code, aborting Java compilation
ERROR writing Java code

I have tried both JDK 7 and 8, x86 and x64, with no success. I have also tried Windows 8, and FitSDK 16.30, same result.

Any ideas? Are there any specific windows or JDK requirements for FitGen.exe? Is there a FitGen for Mac or linux?

Thanks
     

Hello palermo,

We currently target Java 6 with the FIT SDK so try compiling with a Java 6 JDK.

We are also evaluating migration to Java 7, but we have no plans to do so at this moment.

I suspect that the "Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true" is causing the problem here.

If a _JAVA_OPTIONS environment variable exists on your system, removing it might solve this issue.

Make sure that you write the information in the variable down somewhere so you can restore it if necessary.

Mario, that was indeed the problem, thanks a lot!
