How to use karel.jar in eclipse without installing the Stanford version of eclipse and with JRE7?

Question

I'm trying to play with Karel the robot as proposed in the CS106A online course from Stanford University. I do not want to install the old version of Java and eclipse as suggested by the documentation. I found tutorials explaining how to do it, on a standalone eclipse installation, and even a thread in stackoverflow, but they are all based on JRE6.

Is there a way to make it work with JFE7?

Thanks in advance.

Additional questions, that I will probably find obvious in the coming weeks:

• Why does this library not work with JRE7? (I expect newer lib not to work with older JRE, but no the contrary)
• How do you force the compilation with an older JRE in eclipse? Can you do it without installing JRE6?
• How can I know the compatibility of the .jar file?

Thanks again.

Answer 1

I wanted to do the same but it didn't work, you can use new eclipse but not a new jre. in case you want to use a new eclipse you have to copy all the plugins from the old eclipse to the new one.
