I have read that you need the kotlin-maven-noarg compiler plugin for entity classes in order for it to generate default-parameter less cosntructor.
But the application does not start with the following error:
No default constructor for entity
Can you tell me what am I doing wrong?

test class:
@RunWith(SpringJUnit4ClassRunner::class)
@ContextConfiguration(classes = arrayOf(VedicaConfig::class))
class InitStructures {
private var vedicaDBInit: VedicaDBInit? = null
@Before
fun init() {
vedicaDBInit = VedicaDBInit()
}
@Test
fun initClientFolders() {
}
}
I'm using Intellij IDEA with Kotlin 1.1.0, so for deployment I just click debug/run with Tomcat run configuration selected and for running test I just right click on the test class and also click run/debug.
