HTML report in testrunner

Hello,
We are currently running a few projects via jenkins. Jenkins will run one projects at a time and soapUI in turns runs one test case at a time as well.

I use the following script:

# clean-up
rm -f *-report-*.zip
for i in XML_Header_Validation_TestSuite WebService_Header_Validater_TestSuite CommonSoapTester; do
rm -rf "report-${i}"
/bin/testrunner.sh -s"${i}" -r -a -j -f"report-${i}" "middleware_validator-soapui-project.xml"
zip -r ${BUILD_ID}-report-${i} report-${i}
done

But the HTML Report generation in jenkins always failing. Any ideas?
