After installing HPA 10 IDE and creating sample project "Hello World", the compilation failed.
The console log specifies that there is a problem with JDK version (invalid target release: 1.7)
The precondition of HPA 10 IDE (correct for build 330) is JDK 1.7. If you have other JDK preinstalled on your machine, please install version 1.7
Thanks for the information.
I was looking for an answer to this question but since I did not get any answer, I was hoping may be you can help me here.
