Kotlin 在本地機器上正確編譯項目，但通過 Jenkins 拋出異常

Question

我有一個庫，其中有一個伴隨對象值，如下所示

companion object {
    const val QUEUE_CLUSTER_ID = "Commands"
}

我的項目的一類依賴於這個庫使用 lib 的 QUEUE_CLUSTER_ID val，如下所示

data class CreateCatalogItemCommand(
    @JsonProperty("styleVariant") val styleVariant: StyleVariant?) : Commandable() {

    companion object {
        const val QUEUE_ID =  QUEUE_CLUSTER_ID.plus("CreateCatalogItemCommand")
    }
}

問題是 kotlin 在我的機器上正確編譯了項目，但是通過 jenkins 我得到以下錯誤。 當 QUEUE_ID 設置為普通字符串時，錯誤消失。

Answer 1

該異常似乎與 kotlin 類型推斷有關。 在我指明類型之后，編譯沒有出錯。 但為什么？ 仍然不明白我的機器如何使用類型推斷進行編譯？

companion object {
    const val QUEUE_CLUSTER_ID: String = "Commands"
}
