list without items throws error #47

Open yshrsmz opened 2 years ago

yshrsmz commented 2 years ago 
@Serializable
data class Item(
    val name: String,
    val options: List<String> = emptyList()
)

@Test
fun list_test() {
    val yamlString = """
        name: nameValue
        options:
    """.trimIndent()

    val result = Yaml.decodeFromString(Item.serializer(), yamlString)

    assertThat(result).isEqualTo(Item(name = "nameValue", options = emptyList()))
}

The above test case throws the following error, but I think it should be parsed without error.

Top-level decoder: deserializing nested class for 'options' in 'com.codingfeline.buildkonfig.gradle.yaml.Item'
options:
       ^ at line 2, column 9
