We use this script and it works so far. I didn't write it, so I can't any answer any question, but maybe it helps
We added it as Event SubmitListener.before Submit
// Import the required classes
import com.eviware.soapui.impl.rest.actions.oauth.OltuOAuth2ClientFacade
import com.eviware.soapui.support.editor.inspectors.auth.TokenType
import com.eviware.soapui.model.support.ModelSupport
def authProfileName = "PROFILE_NAME"
if(!submit.getRequest().getAuthType().asBoolean()){
return // stop if the auth type is null, for example jdbc requests
}else if(submit.getRequest().getActiveAuthProfile() == null){
return // stop if the auth profile is null
}else if(authProfileName == submit.getRequest().getActiveAuthProfile().getName()){
// Set up variables
def project = ModelSupport.getModelItemProject(context.getModelItem())
def authProfile = project.getAuthRepository().getEntry(authProfileName)
def oldToken = authProfile.getAccessToken()
def tokenType = TokenType.ACCESS
// Create a facade object
def oAuthFacade = new OltuOAuth2ClientFacade(tokenType)
// Request an access token in headless mode
oAuthFacade.requestAccessToken(authProfile, true, true)
// Wait until the access token gets updated
//while(oldToken == authProfile.getAccessToken()) {}
//The sleep method can be used instead of a while loop
//sleep(3000)
for(int i = 0; i<=3000; i++){
if(oldToken != authProfile.getAccessToken()){
break
}
sleep(1)
}
// Post the info to the log
log.info("Set new token: " + authProfile.getAccessToken())
}
