SoapUI NG Pro Jenkins integration issue - Import License

Hi, 

We are using the 1.4.0 version of Ready API with SoapUI NG Pro. We have floating licenses for our machines and for Continuous integration as well.

The old test jobs use the old 5.0.0 SoapUI Pro Maven plugin, but for a new project, we wanted to use the latest version, since the licenses apply to the NG Pro as well.

The problem came, when I've tried to use the latest Maven plugin for the Jenkins job. The job fails with the following:

00:48:14,170 INFO  [DefaultSoapUICore] All plugins loaded
No valid SoapUI NG license exists.
Do you want to install a license? [y/N]: [ERROR] java.util.NoSuchElementException

...

[ERROR] Failed to execute goal com.smartbear:ready-api-maven-plugin:1.4.0:test (default-cli) on project shpm-soapui-project: Ready! API Test(s) failed -> [Help 1]

My managers assured me, that the "old" SoapUI Pro licenses have to work until the end of this year. There is proof for that, since the old jobs are running just fine.

My question: Is the old SoapUI Pro floating license for Jenkins valid for the Ready API and NG Pro integration? Should we buy a new floating license for the NG CI integration?

Note: I've searched the forums for solutions, every single thread shows, that I have to update the dependencies to 1.4.0 and the issue is going to be fixed. Did that, nothing helps.

Nandor
