runnodes 时发生了非法的反射访问操作

Question

我正在尝试运行我的 corda 节点，但我遇到了一个奇怪的问题，节点正在正确启动，正如您在日志中看到的那样

C:\Repositorio\cordapp-template-kotlin\build\nodes>runnodes --log-to-console --logging-level=DEBUG
Starting nodes in C:\Repositorio\cordapp-template-kotlin\build\nodes
Starting corda.jar in C:\Repositorio\cordapp-template-kotlin\build\nodes\Notary on debug port 5005
Starting corda.jar in C:\Repositorio\cordapp-template-kotlin\build\nodes\PartyA on debug port 5006
Starting corda-webserver.jar in C:\Repositorio\cordapp-template-kotlin\build\nodes\PartyA on debug port 5007
Starting corda.jar in C:\Repositorio\cordapp-template-kotlin\build\nodes\PartyB on debug port 5008
Starting corda-webserver.jar in C:\Repositorio\cordapp-template-kotlin\build\nodes\PartyB on debug port 5009
Started 5 processes
Finished starting nodes

然而，当它打开 5 个控制台以实际运行 Web 服务和节点时，它就发生了。

控制台打印屏幕：

有没有人遇到过同样的问题？我不知道如何调试它。

Answer 1

你是运行 Java 10. Corda 仅在 Oracle JDK 8 JVM 的 8u131+ 版本上受支持。

您可以在此处查看所需的 Java 版本：https://docs.corda.net/getting-set-up.html。

Answer 2

在File > Project Structure... to 1.8.0_242下更改Project SDK后，您可能还需要unlink和link Gradle 再次通过：

右键单击 Gradle window 上的 Gradle 项目，然后单击 Unlink Gradle Project
转到File > Close Project
再次打开您当前的项目，您将看到一条消息IntelliJ IDEA found a Gradle build script
点击下方的Import Gradle Project等待完成。

我写这篇文章是因为我不小心在 Java 11 环境中导入了 Gradle。但是，在更改项目 SDK 后，由于 java.lang.IllegalArgumentException 错误，我仍然无法运行单元测试。
