hi,
to have xml junit result files generated by soapui, you need to set the junitReport parameter to true. Additionnaly, configure the outputDirectory parameter to a specific location otherwise soapui generates file in the jvm "user.dir" (usually the root directory of your maven project). Generally, maven users set it to a subdirectory of ${project.build.directory}.
Then you can use jenkins junit plugin to publish the junit report (configure path to the soapui output directory and include all xml files)
You provide a maven-surefire-report-plugin configuration. Does this mean you want maven to also generate junit html reports?
