This is what showed up today, in the file.
I started eclipse and got the same error message.
I did a clean build, no error message, but the blink application did not launch. I looked more closely and saw this.
showing that a command failed, perhaps this is useful, to you. It is unclear to me what is happening.
Ok, I did a complete wipe of the Java installations on the machine and reinstalled the latest .
Eclipse loaded with out warnings or errors, but once I tried to compile I got this.
I will keep 3.5 for now to assist in any further testing / help you may require to assist in getting this resolved.
