我正在将cordapp从Corda v1.0迁移到Corda v4.0。我正在遵循逐步迁移方法。

将cordapp从Corda v1.0迁移到Corda v2.0时，节点已成功部署并运行，但是在运行Springboot Web服务器时，我得到了错误-“ java.lang.ClassNotFoundException：net.corda.bgc。合同cmd窗口中的“ contract.State”。

[节点和Web服务器在Corda v1.0中成功运行。]

以下是错误的详细信息-

Springbootweb服务器成功启动后会冻结 连接到CorDapp时。以下是Web服务器cmd窗口中的stacktrace-

通过将cordapp jar文件复制到每个节点的“ plugins”目录中，该问题得以解决。

在Corda V1中，该过程将cordapp jar文件复制到每个节点的“ plugins”目录中，而在Corda V2中，似乎我们必须手动进行。如果我错了，请纠正我。
