getting error in Ant build junitreporting

Question

When I am trying to build without junitreport its working fine. However, I need the junit report in html format ultimately with all the successful or failed scripts. Please suggest where I am going wrong. Any help would be appreciated.

Answer 1

this is an issue inside ant...

you can fix this by downloading two jars from the ant homepage: org.apache.xalan org.apache.xml.serializer

put these files below C:\Windows\Sun\Java\lib\ext in my case the lib and ext folder didn'T exist if this is the case just create them. reboot eclipse and everything will work fine. (it did for me so on two pc's and also a lot of mates at my subject did have the same issue and this solution worked for all of them)

regards

Answer 2

I had the same issue running from eclipse kepler with ant 1.8.4 and java 5 or 6.
It works from the command line, ant 1.7.0, with java 5 or 6.

Answer 3

I had this same issue after upgrading from Java 6 to Java 7. I was able to workaround the issue by running ant on the command-line using Ant 1.9.0.

Unfortunately, switching to Ant 1.9.0 in Eclipse (per these instructions: How to upgrade the ant built into eclipse?) didn't address the issue when running Ant within Eclipse, but running on the command-line is working, so that's what I'm using.
