I'm trying to use FitGen.exe to create a new profile, but that is failing so I tried to run FitGen.exe immediately after unpacking FitSDKRelease_20.14.00.zip.

I'm using JDK 8 u111, Windows 8.1, latest security updates.

The output of FitGen.exe is fine for c, cpp, and C#, but not for Java:

Hello,

Unfortunately we only support generating a jar using Java 6 at this time. Please try pulling down a Java 6 JDK and try to compile it using that.

Ah, I thought I had read to use the latest JDK.
Now to find a Java 6 JDK....

Okay, I installed JDK 6.0_45. Same error. What other explanations are possible?

Is there any way to get more information that can help diagnose the problem?

Hello, it is likely still calling your Java 8 JDK. Can you add Java 6 to your path?

I did add Java 6 to my path. I removed Java 8 from the VM (Windows 8.1). I modified the PATH variable right before calling FitGen.exe. And I ran FitGen.exe from a newly downloaded, newly unzipped, FitSDKRelease_20.14.00.zip

Here is a bit of cmd.exe information:

C:\FitSDKRelease_20.14.00>where.exe java.exe

So, is there anyway to get more information from FitGen.exe? Can I send you a zip file of the java directory that FitGen.exe creates to help you determine where the error is occurring beyond the 42%?

After Switching SDKs do you still see:

com\garmin\fit\Decode.java:222: warning: [overloads] addListener(MesgListener) i
n Decode is potentially ambiguous with addListener(MesgDefinitionListener) in De
code
   public void addListener(MesgListener mesgListener) {
               ^
83 warnings
Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true 

or has the error reduced to just:

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
14%
Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
21%
Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
28%

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
42% Errors present in Java code, aborting Java compilation
ERROR writing Java code. 

If you remove the _JAVA_OPTIONS environment variable does the build work?

I just ran into this today as well. Additional hint: Use 32-bit version of jdk 6.

Okay, now I'm trying Java 6u45 for x86:

Looks like your _JAVA_OPTIONS variable is still set.

Ah, that seems to have been an issue:

c:\FitSDKRelease_20.14.00>echo %_JAVA_OPTIONS%
-Djava.net.preferIPv4Stack=true

c:\FitSDKRelease_20.14.00>set _JAVA_OPTIONS=

c:\FitSDKRelease_20.14.00>FitGen.exe -java java
FIT Code Generator - Protocol 2.00  Profile 20.14Release
SDK Version: production/akw/20.14.00-0-g448ef52
Parsing existing config.csv...
Writing new config.csv...
Generating Java code...
Building Java tools...100% 

So, can the documentation please be updated?
- Windows
- Java JDK 6 32bit
- no _JAVA_OPTIONS

And/or can a issue be created to track this problem?

Thanks for your help!

We have released a new version of the SDK which addresses this issue.
