本文介绍了JHipster 7.1.0：无法生成网关，无法实例化提供程序reactor.blockhound.junit.platform.BlockHoundTestExecutionListener的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用Java OpenJDK 11.0.11、JHipster 7.1.0和Node v14.17.3我正在创建一个简单的微服务(一个后端和一个网关)，但是JHipster无法使用jdl命令(jdl-import)创建，它抛出

它确实创建了文件夹blogBackend、blogGateWay和docker-compose...但文件夹BlobBackend为空。

我在此thread

中发布了上述内容

如果我转到BloGateWay并运行：MVN全新安装

我也收到异常；

您知道如何解决此问题吗？

下面是我使用的jdl文件(blog.jdl)：

}


microservice * with blogBackend

deployment {
  deploymentType docker-compose
  appsFolders [blogGateWay, blogBackend]
  dockerRepositoryName "carestra"

}

复制步骤：1-创建文件夹博客2-移动到文件夹博客3-run：jhister JDL blog.jdl4-移动到博客网关5-运行：MVN全新安装

运行：jhpster info om文件夹博客给我；

推荐答案

这与J9(而不是热点)VM有关。请参见https://github.com/reactor/BlockHound/issues/21

这篇关于JHipster 7.1.0：无法生成网关，无法实例化提供程序reactor.blockhound.junit.platform.BlockHoundTestExecutionListener的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
