gradle - java.lang.IllegalArgumentException带Kotlin的Corda转换存储库

Question

我尝试在带有TDD的Kotlin Corda转换存储库中编写契约(Contract)。所有IOUIssueTests均失败。

我有jdk 1.8.0_211。 Gradle 5.5。并安装了kotlin插件。借条状态也得到执行。

这是我的5 IOUIssueTest的IOUContract:

 package net.corda.training.contract

    import net.corda.core.contracts.*
    import net.corda.core.transactions.LedgerTransaction
    import net.corda.training.state.IOUState
    /**
     * This is where you'll add the contract code which defines how the [IOUState] behaves. Look at the unit tests in
     * [IOUContractTests] for instructions on how to complete the [IOUContract] class.
     */
    @LegalProseReference(uri = "<prose_contract_uri>")
    class IOUContract : Contract {
        companion object {
            @JvmStatic
            val IOU_CONTRACT_ID = "net.corda.training.contract.IOUContract"

        }


        /**
         * Add any commands required for this contract as classes within this interface.
         * It is useful to encapsulate your commands inside an interface, so you can use the [requireSingleCommand]
         * function to check for a number of commands which implement this interface.
         */
       interface Commands : CommandData {

            class Issue : TypeOnlyCommandData(), Commands
        }

        /**
         * The contract code for the [IOUContract].
         * The constraints are self documenting so don't require any additional explanation.
         */
        override fun verify(tx: LedgerTransaction) {
            val command = tx.commands.requireSingleCommand<Commands>()

            when (command.value) {

                is Commands.Issue -> {
                    requireThat {
                        "No inputs should be consumed when issuing an IOU." using (tx.inputs.isEmpty())
                        "Only one output state should be created when issuing an IOU." using (tx.outputs.size == 1)
                        val iou = tx.outputStates.single() as IOUState
                        "A newly issued IOU must have a positive amount." using (iou.amount.quantity > 0)
                        "The lender and borrower cannot have the same identity." using (iou.lender !== iou.borrower)
                        "Both lender and borrower together only may sign IOU issue transaction." using(iou.participants.toSet() == iou.participants.map { it.owningKey}.toSet())

                    }
                }

            }

        }
    }

但是，当我运行IOUIsuueTest.kt时，出现以下错误:

java.lang.IllegalArgumentException: Attempted to find dependent attachment for class net/corda/core/contracts/TypeOnlyCommandData, but could not find a suitable candidate.

错误已修复。我已经使用过Kotlin单元测试。 Kotlin Unit Test
