VerifyError - main method can only throw Throwable.

Posted: Apr 10, 2009 6:40 PM

Hi. I cannot execute the scalatest ant task. It throws the following exception:

java.lang.VerifyError: (class: org/scalatest/tools/Runner$, method: main signature: ([Ljava/lang/String;)V) Can only throw Throwable objects
at org.scalatest.tools.Runner.main(Runner.scala)
at org.scalatest.tools.ScalaTestTask.execute(ScalaTestTask.java:197)
...

I have the following versions:

java -version
java version "1.5.0_18"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_18-b02)
Java HotSpot(TM) Client VM (build 1.5.0_18-b02, mixed mode, sharing)

scala -version
Scala code runner version 2.7.3.final -- Copyright 2002-2009, LAMP/EPFL

scalatest
982957 2009-03-04 12:13 scalatest-0.9.5.jar

build.xml extract


   <path id="scalatest.classpath">
       <path location="test/lib/scalatest-0.9.5.jar" />
       <path location="src/lib/scala-library.jar" />
   </path>
   <taskdef name="scalatest" classname="org.scalatest.tools.ScalaTestTask">
      <classpath refid="scalatest.classpath"/>
   </taskdef>
   <target name="tested-classes" ... >
      <scalatest>
         <suite classname="au.com.loftinspace.scalachess.game.SquareSpec" />
      </scalatest>
   </target>

Can anyone offer me a clue on this?

Thanks
Jeremy

The same error occurs with:

java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing)

I just solved my own problem by chance.

The scala-library.jar which is in the src libs did not correspond to the scala version that was installed. I copied scala.home/lib/scala-library.jar to my src libs and all is well.
