I used the Javah function in below manner.
apply plugin: 'cpp'
apply plugin: 'java'
//-- set the group for publishing
group = 'com.rohit.singh'
/**

*/
def buildProperties = new Properties()
file("version.properties").withInputStream {
stream -> buildProperties.load(stream)
}
//add the jenkins build version to the version
def env = System.getenv()
if (env["BUILD_NUMBER"]) buildProperties.ncdefBuildVersion += "_${env["BUILD_NUMBER"]}"
version = buildProperties.anal
println "${version}"
//name is set in the settings.gradle file
group = "com.rohit.singh"
version = buildProperties.anal
println "Building ${project.group}:${project.name}:${project.version}"
