SoapUI Project Report doesn't work using SoapUI Pro and Maven

Hi,   I am using SoapUI Pro 5.1.2 and run my project with the maven plugin. I want to include a SoapUI Pro "Project Report" in HTML Format.   Therefore I follow https://community.smartbear.com/t5/SoapUI-NG/SOLVED-SoapUI-Pro-Maven2-plugin-questions/m-p/11469#M4918 and unzip SoapUI at the Jenkins Server to have the SoapUI bin folder.

Can anybody tell me why the Project Report still doesn't work?

Here is my pom:

...
<plugin>
<groupId>com.smartbear.soapui</groupId>
<artifactId>soapui-pro-maven-plugin</artifactId>
<version>5.1.2</version>
<configuration>
<environment>${soapui.environment}</environment>
<junitReport>true</junitReport>
<printReport>true</printReport>
<exportAll>true</exportAll>
<reportName>Project Report</reportName>
<reportFormat>HTML</reportFormat>
<projectFile>xxx.xml</projectFile>
<outputFolder>${project.basedir}/target/soapui-reports</outputFolder>
<soapuiProperties>
	<property>
		<name>soapui.home</name>
		<value>/home/qa/SoapUI-Pro-5.1.2-m-SNAPSHOT/bin</value> 
	</property>
</soapuiProperties>
</configuration>
...

Regards
