Exception thrown initialising LESS Engine on 1.5.1 #57

Closed Tzrlk closed 10 years ago

I encountered this exception after upgrading from 1.3.0 (where imports didn't work), to 1.5.1.

This is very likely caused by an old Rhino version in your classpath. The library is tested against "Rhino 1.7 release 4 2012 06 18".

I don't know why an old version of Rhino would be on the classpath. I've got the rhino-1.7R4 artefact being brought in (maven build), so it reporting 1.6 on the console, and referencing everything from the 1.7 jar is a little confusing. Though it does look like my IDE is doing some stupid caching. I'll update again when I've looked into it further.

Found it. com.yahoo.platform.yui:yuicompressor brings in rhino:js:jar:1.6R7.
