Console broken with scala 2.9.0 #167

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
"Failed to created JLineReader: java.lang.NoClassDefFoundError: 
scala/tools/jline/console/completer/Completer Falling back to SimpleReader."

What steps will reproduce the problem (please be specific)?
Open an sbt project that uses scala 2.9.0 and execute the `console` action.

What is the expected behavior? What do you see instead?
Stuff I type into the console should appear on the screen; instead, no text 
appears, but the console still receives input.  Above error message is printed. 
 Example:
{{{
Failed to created JLineReader: java.lang.NoClassDefFoundError: 
scala/tools/jline/console/completer/Completer
Falling back to SimpleReader.
Welcome to Scala version 2.9.0.final (Java HotSpot(TM) 64-Bit Server VM, Java 
1.6.0_20).
Type in expressions to have them evaluated.
Type :help for more information.

scala> <console>:8: error: not found: value sdfsdf
       sdfsdf
       ^

scala> <console>:8: error: not found: value asdf
       asdf
       ^

}}}

What versions of the following are you using?

Java: 1.6.0_20
Scala: 2.9.0
sbt: 0.7.7
Operating system: Mac OS X 10.6.6

Please provide any additional information below.

I thought that the braces were needed for appropriate code formatting, as is 
the case with Trac, but I guess they're not.

No problem on the braces- it is annoying that you can't preview reports.

As for the report, this works for me.  Perhaps the download was interrupted, in 
which case I suggest removing
 project/boot
and
 ~/.ivy2/cache/org.scala-lang/scala-compiler/jars/scala-compiler-2.9.0.jar
and
 ~/.ivy2/cache/org.scala-lang/scala-compiler/jars/scala-library-2.9.0.jar

Otherwise, we can troubleshoot on the mailing list and reopen if necessary.

Thanks for the quick response!  I've been able to reproduce this problem on a 
second machine (same Mac OS version, scala version, java version), and have 
found this post on the scala-user mailing list from a windows user with a 
similar issue: 
http://groups.google.com/group/scala-user/browse_thread/thread/c31745e394b8fce0/
518fc887c88d1966 (archive: 
http://permalink.gmane.org/gmane.comp.lang.scala.user/39752).  Deleting the 
directories did not fix the problem.  I've found a thread on this issue on the 
mailing list, so I'll post there.

Just in case anyone else has this problem and finds their way here via google, 
the suggestion in the following thread solved this issue for me:

FWIW the procedure that worked for me was to explicitly and in this order:

update the sbt-launcher to 0.7.7 (and the sbt version in your project)

rm -r ~/.ivy2/*
cd {projectdir}
rm -r project/boot/*
sbt update

doing only a couple of these or not in the above order wasn't working.

Yep I had the same problem on Mac OSX and the comment 5 above did the trick - 
thanks!

I can confirm that comment #5 fixes everything as well.

Doesn't work for me. I deleted my .ivy2, my .m2/repositories, my project/boot, 
updated, and the problem still happens with me. Using Scala 2.9.0-1.

I can also confirm that the steps given in comment #5 work.
