Re: Possible bug in Ant 1.8.0

[Antoine Levy Lambert]

Hello Petar,

Thinking loud ...

You made me google for ClassCircularityError. Do you know which classes 
are meant to have circular dependencies upon each other ?

I have a look at the source code of EachTestNotifier [1]. This class 
uses org.junit.runner.notification.Failure.

I do not see quickly what is supposed to be circular.

Do you have maybe two different versions of junit somewhere in the 
classpath ?

Regards,

Antoine

Regards,

Antoine

Hi Ivan,

nice catch ;) Yep, it works with the fork attribute.

Thanks I'll buy you some shots of rakia ;)

P.S. @Antoine or@ Stefan or @Steve, if you confirm this as
a bug, I will open a ticket in the jira.

Hello Petar,

Please try with fork="yes" attribute of junit task.

Subject: Possible bug in Ant 1.8.0

Hi guys,
      
I was running the tests for my book with the latest version of
    
Ant:
      
Apache Ant version 1.8.0 compiled on February 1 2010

and Ivy
    
(version 2.1.0) and the tests in chapter 6 fail with the error:
      
BUILD

I
    
am using Java:
      
java version "1.6.0_18"
Java(TM) SE Runtime Environment
    
(build 1.6.0_18-b07)
      
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed
    
mode)
      
and Ubuntu 9.1 66 edition. The funny thing is that it doesn't work
    
with Ant
      
1.8.0RC1
but downgrading to Ant 1.7.0 and the build works just
    
fine.
      
If you want to test it you can checkout the source of the book from
    
here:
      
    
href="
      
https://junitbook.svn.sourceforge.net/svnroot/junitbook/trunk/junitbook2/";
    
target=_blank
      
https://junitbook.svn.sourceforge.net/svnroot/junitbook/trunk/junitbook2/

and
    
go to chapter 6 and execute ant test.
      
Has anyone seen this error
    
before?
