I'm trying to use a Java library (no source code available) which defines some xxx.xxx.object package. Scala complains about the presence of "object" in the package name, so I can't import from it, and I can't refer to its classes with fully qualified name either.
Is there a way around it?

To complete agilefall's answer, the Scala Language Specification mentions that an import is composed of id
:
id ::= plainid
| ‘\`’ stringLit ‘\`’
an identifier may also be formed by an arbitrary string between back-quotes (host systems may impose some restrictions on which strings are legal for identifiers). The identifier then is composed of all characters excluding the backquotes themselves.
Backquote-enclosed strings are a solution when one needs to access Java identifiers that are reserved words in Scala.
For instance, the statementThread.yield()
is illegal, sinceyield
is a reserved word in Scala. However, here’s a work-around:
Thread.`yield`()

Wrapping the object in a ` (the quote next to 1) should work.
xxx.xxx.`object`
