Question

我有一个可工作的Corda Gradle版本。我们的deploy1Node任务可以通过IntelliJ，Windows中的cmd和MacOS中的iTerm正常运行。

对于此特定版本，我们正在使用 corda-3.2开源（net.corda:corda-3.2:...）。 3.3开源也会出现此问题，并且 ubuntu上的Oracle Java版本“ 1.8.0_171”，mac上的Oracle Java版本“ 1.8.0_152”。

当我尝试在Linux系统中执行它时，出现以下错误

Caused by: java.lang.ClassCastException: sun.nio.fs.UnixPath cannot be cast to java.lang.String

，如下面的堆栈跟踪摘录所示：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':deploy1Node'.

无论平台如何，该任务如何工作？

开源jar版本是：

Corda-Revision: 5ae8325980ad22df8146b983afeaca344fc03c3e
Corda-Vendor: Corda Open Source
Corda-Release-Version: 3.2-corda

企业版似乎还可以：

Corda-Revision: c9b23a4400923a5cfe88271ce2fedd75740eac40
Corda-Vendor: Corda Enterprise Edition
Corda-Release-Version: 3.1

尝试找出此问题，我发现在企业版中它显示在gradle构建中：

> Task :deploy1Node
Putting task artifact state for task ':deploy1Node' into context took 0.0 secs.
Executing task ':deploy1Node' (up-to-date check took 0.0 secs) due to:
  Task has not declared any outputs.
Running Cordform task
Deleting ./build/nodes
Bootstrapping local test network in /mnt/builds/Cordapp/appname/build/nodes
Generating node directory for Node
Copying CorDapp JARs into node directories

，在开源版本中，输出为：

> Task :deploy1Node
Putting task artifact state for task ':deploy1Node' into context took 0.0 secs.
Executing task ':deploy1Node' (up-to-date check took 0.0 secs) due to:
  Task has not declared any outputs.
Running Cordform task
Deleting ./build/nodes
Bootstrapping local network in /mnt/builds/Cordapp/appname/build/nodes
Node config files found in the root directory - generating node directories
Generating directory for Node_node
Nodes found in the following sub-directories: [Node_node]

似乎将_node附加在不应附加的位置。

为防止出现此问题，请确保您的ext.corda_release_group，ext.corda_release_version和ext.corda_gradle_plugins_version 在您的任何buildscript会话中定义一次一次和一次项目恰好有。

该问题是由于尝试让build.gradle在 2种不同的Corda发行版（开源和企业版）-并在首次使用后更改 default 选项。对于open source，build.gradle的{{1}}部分必须具有以下设置：

buildscript

同样，对于企业版，设置必须类似于：

buildscript {
...
            ext.corda_release_group = 'net.corda'
            ext.corda_release_version = '3.2-corda'
            ext.corda_gradle_plugins_version = '3.0.9'
            ext.kotlin_version = '1.2.50'
...

一旦选择，引用就会纠缠在一起，并且buildscript { ... ext.corda_release_group = 'com.r3.corda' ext.corda_release_version = '3.1' ext.corda_gradle_plugins_version = '4.0.25' ext.kotlin_version = '1.2.50' ...任务在开源版本中失败。

一种可能性是使用类似的东西：

deploy1Node

为什么我的deploy1Node任务无法抱怨java.lang.ClassCastException：sun.nio.fs.UnixPath无法转换为java.lang.String？
