However, authorization credentials are not imported in this way and you have to manually enter and save them in Soap UI requests. Re: A required class was missing while "Cell Constraints" Adding the following in pom.xml resolved the issue: (Thanks to the solution in https://community.smartbear.com/t5/SoapUI-Open-Source/soapui-maven-plugin-5-4-0-is-not-working/td-p/171251 and documentation in https://www.soapui.org/test-automation/maven/maven-2-x.html ) <build> <plugins> <plugin> <groupId>com.smartbear.soapui</groupId> <artifactId>soapui-maven-plugin</artifactId> <version>5.4.0</version> <dependencies> <dependency> <groupId>com.jgoodies</groupId> <artifactId>forms</artifactId> <version>1.2.1</version> </dependency> </dependencies> </plugin> </plugins> </build> Also, assuming that the following has already been added to settings.xml: <pluginRepositories> <pluginRepository> <id>smartbear-sweden-plugin-repository</id> <url>http://www.soapui.org/repository/maven2/</url> </pluginRepository> </pluginRepositories> Thanks!
