Java: Getting a "Requires JDK 5.0 or later" error in Eclipse

I have just installed the JDK1.8.0 32 bit version on my computer and that all seemed to work nicely. I then followed the instructions on this stackoverflow page to add tools.jar to the Eclipse (although, to be honest, I'm not quite sure what that means?). I'm still getting the error: "Requires JDK 5.0 or later. Please download it from http://java.sun.com/j2se/1.5/".

Could someone please help me understand what the problem is? Also, please let me know if I haven't given enough information, this is my first attempt at using Eclipse and I don't know if you need any other info.

Thanks

Mike

When you make a new project, make sure it's using the JRE you want. You may have to change it from default to "use project specific JRE", and then select the 1.8.

The Oracle JDK installation does not install Java in the location where Eclipse by default looks for it.

I would suggest that you go to http://java.com/en/download/installed.jsp and follow instructions to get a default Java installation on your system.

Eclipse will then use that to run itself. You can then tell Eclipse about your Java 8 JDK in Preferences -> Java -> Installed JRE's and that it is to be used by default by the projects you write.

Note that there is not full support for the new Java 8 facilities in Eclipse yet. That will most likely come in Eclipse 4.4 scheduled for June (http://wiki.eclipse.org/Simultaneous_Release)
