[ERROR]TransactionBuilder. - The transaction currently built is missing an attachment for :classnet/corda/core/contracts/CommandData

问题

当尝试运行 Corda 测试时，给定的测试案例出现以下错误。我正在使用 JDK 1.8 和 Intellij IDEA。

MetalContract

package com.template.contracts;

import com.template.states.MetalState;
import net.corda.core.contracts.Command;
import net.corda.core.contracts.CommandData;

import net.corda.core.identity.Party;
import net.corda.core.transactions.LedgerTransaction;
import org.jetbrains.annotations.NotNull;

import java.security.PublicKey;
import java.util.List;

public class MetalContract implements Contract {
    public static final String CID = "com.template.contracts.MetalContract";

    @Override
    public void verify(@NotNull LedgerTransaction tx) throws IllegalArgumentException {
        // Contract verification logic
        // ...
    }

    public static class Issue implements CommandData {}
    public static class Transfer implements CommandData {}
}

package com.template.contracts;

import com.template.states.MetalState;
import com.template.contracts.MetalContract;
import net.corda.core.contracts.Contract;
import net.corda.core.identity.CordaX500Name;
import net.corda.testing.core.TestIdentity;
import net.corda.testing.node.MockServices;
import org.junit.Test;

import static net.corda.testing.node.NodeTestUtils.transaction;

public class ContractTests {
    private final TestIdentity Mint = new TestIdentity(new CordaX500Name("mint", "", "GB"));
    private final TestIdentity TraderA = new TestIdentity(new CordaX500Name("traderA", "", "GB"));
    private final TestIdentity TraderB = new TestIdentity(new CordaX500Name("traderB", "", "GB"));

    private final MockServices ledgerServices = new MockServices();

    private MetalState metalState = new MetalState("Gold", 10, Mint.getParty(), TraderA.getParty());
    private MetalState metalStateInput = new MetalState("Gold", 10, Mint.getParty(), TraderA.getParty());
    private MetalState metalStateOutput = new MetalState("Gold", 10, Mint.getParty(), TraderB.getParty());

    @Test
    public void metalContractImplementsContract() {
        assert (new MetalContract() instanceof Contract);
    }

    @Test
    public void MetalContractRequiresTheIssuerToBeARequiredSignerInTheTransaction() {
        // Test logic
        // ...
    }
}

错误信息如下：

[ERROR] 12:35:10,086 [main] transactions.TransactionBuilder. - The transaction currently built is missing an attachment for class: net/corda/core/contracts/CommandData.
Attempted to find a suitable attachment but could not find any in the storage.

似乎您的项目结构有问题，因为出现了一个核心包的 NoClassDefFoundError 错误。

尝试关闭项目，还有将项目从最近项目列表中移除。
然后打开项目文件夹，按照提示选择“导入 Gradle 项目”。

英文:

It looks like something wrong with your project structure since it is a NoClassDefFoundError of a core package.

Try closing the project and also removing the project from your recent project list.
And open the project folder then follow the prompt to import Gradle project.

选择“编辑配置”并选择“JAR清单”作为“缩短命令行”：

[ERROR]TransactionBuilder. – The transaction currently built is missing an attachment for :classnet/corda/core/contracts/CommandData

英文:

Edit Configurations and choose "JAR manifest" for "Shorten command line":

[ERROR]TransactionBuilder. – The transaction currently built is missing an attachment for :classnet/corda/core/contracts/CommandData
