【问题描述】：
我已经从here下载了示例cordapp的源代码。
发出命令时出现以下错误：
gradle deployNodes.
请指导我可以做什么。 注意：这是 Corda V3。

【问题讨论】：
-
如果我从 corda-v2 分支下载代码库，则不会遇到问题。
-
corda_gradle_plugins_version = '3.0.9' 插件版本存在一些问题。尝试从 V2 迁移到 V3 时遇到同样的问题。
-
你用的是什么JVM？
-
我正在使用 JDK 1.8 更新 java 版本 "1.8.0_152" Java(TM) SE Runtime Environment (build 1.8.0_152-b16) Java HotSpot(TM) 64-Bit Server VM (build 25.152- b16，混合模式）。
-
在从 V2 迁移到 V3 时也遇到了同样的问题。我不得不在我的项目中将 Gradle 从 4.5.1 降级到 4.4.1 才能让它再次工作。
