I have the following code:

def mavenPom = readMavenPom(file: "pom.xml")

if (mavenPom.getScm() == null){
 org.apache.maven.model.Scm mavenScm = new org.apache.maven.model.Scm()
 mavenPom.getScm().setConnection("scm:git:${scmModel.scmRepository.url}")
 mavenPom.setScm(mavenScm)
}

 I'm getting the following exception.

groovy.lang.MissingMethodException: No signature of method: org.apache.maven.model.Model.setScm() is applicable for argument types: (org.apache.maven.model.Scm) values: [org.apache.maven.model.Scm@a54de52]
Possible solutions: setScm(org.apache.maven.model.Scm), getScm(), setName(java.lang.String), setUrl(java.lang.String), getId(), getName()
