[ANN] JFlex support 1.2.0 released

Hi, I am using this with IDEA 7.0.4 build 7757, on mac using the idea jdk (1.5). But getting this error on starting IDEA:

Bad version number in .class file
com.intellij.diagnostic.PluginException: Bad version number in .class file
at com.intellij.openapi.components.impl.ComponentManagerImpl$ComponentsRegistry.a(ComponentManagerImpl.java:2)

at com.intellij.openapi.components.impl.ComponentManagerImpl$ComponentsRegistry.access$100(ComponentManagerImpl.java:29)

I guess my IDEA version is too new, perhaps.

I also tried grabbing the source and building it myself - I get further - I get highlighting on the flex file - but when I try to run the app I get this error:

"JFlex home path is invalid"

No message

There was a request for a TEMPLATE variable definition asked for when I opened the iml file that comes with the source - perhaps I set it incorrectly - any clues on where it should refer to?

Thanks in advance,
Chris

Oops - I did not have the jflex tools stuff below my IDEA folder.

This fixes the second problem above, although I get intermittent errors now when rebuilding about not finding jflex.sh - which is in ]]>/tools/jflex/bin/

I also realised that the downloaded source is 1.1.1 - perhaps thats why I am getting further with it.

Regards,
Chris
