Re: weird error
Bill Venners
I think I have an answer for your issue report here:
https://scalatest.dev.java.net/issues/show_bug.cgi?id=1
I suspect the problem may be a typo in the name of the JUnit Jar file,
or some other problem with that Jar file. I went to junit.org and
downloaded three versions. They had these names:
junit-4.3.1.jar
junit-4.4.jar
junit-4.5.jar
When I compile without a JUnit Jar file (or have a typo in the name),
I get the same error message you get:
bob-vaio:scalatest-0.9.5 bv$ scalac -classpath
scalatest-0.9.5.jar:../../st/lib/ScalaCheck-1.5.jar StackSuite.scala
Exception in thread "main" java.lang.RuntimeException: malformed Scala
signature of JUnit3Suite at 934; reference value junit of package
<root> refers to nonexisting symbol.
at scala.tools.nsc.symtab.classfile.UnPickler$UnPickle.errorBadSignature(UnPickler.scala:762)
at scala.tools.nsc.symtab.classfile.UnPickler$UnPickle.scala$tools$nsc$symtab$classfile$UnPickler$UnPickle$$readSymbol(UnPickler.scala:172)
But when I compile with any of these three JUnit Jar files correctly
included in the classpath, it compiles fine. I also tried running with
all three versions, and they run fine too. Can you double check the
spelling of the name of your JAR file, and if it is correct, try going
to junit.org and downloading one of the official releases? It may be
that the eclipse Jar file you're using may have stripped the old junit
stuff out, which JUnit3Suite uses. (When JUnit went from 3 to 4, the
package name went from "junit...." to "org.junit..." The name
org.junit4_4.3.1 in the eclipse plugins directory makes me think that
you're just not using a full or complete JUnit Jar file.)
Please let me know if this resolves your issue.
Thanks.
Bill
