reactor.blockhound.junit.platform.BlockHoundTestExecutionListener 7.1.0:无法生成网关，无法实例化提供程序JHipster

Question

我使用javaOpenJDK11.0.11、JHipster 7.1.0和节点v14.17.3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)创建，它会抛出

它确实创建了文件夹blogBackend，blogGateWay和停靠-撰写.但是文件夹blogBackend是空的。

我已经在这个thread上发布了上面的内容

如果我移动到blogGateWay并运行：mvn干净安装

我也有例外；

知道怎么解决这个问题吗？

下面是我使用的jdl文件(blog.jdl)：

​

application {
  config {
    applicationType gateway,
    baseName blogGateWay,
    packageName com.carestra.learn.jhipster.gateway,
    authenticationType jwt,
    serviceDiscoveryType eureka,
    buildTool maven,
    reactive true, // default true
    skipClient false,
    skipServer false,
    skipUserManagement false,
    databaseType sql,
    prodDatabaseType postgresql,
    devDatabaseType h2Disk,
    cacheProvider ehcache,
    testFrameworks [cypress]
  }

  entities *
}

application {
  config {
    applicationType microservice,
    baseName blogBackend,
    packageName com.carestra.learn.jhipster.backend,
    authenticationType jwt,
    serviceDiscoveryType eureka,
    buildTool maven,
    reactive true,
    skipClient true,
    skipUserManagement true,
    clientFramework react,
    databaseType sql,
    prodDatabaseType postgresql,
    devDatabaseType h2Disk,
    cacheProvider hazelcast,
    enableHibernateCache true,
    testFrameworks [cypress]
  }

  entities *
}

entity Blog {
  name String required minlength(3)
  handle String required minlength(2)
}

entity Post {
  title String required
  content TextBlob required
  date Instant required
}

entity Tag {
  name String required minlength(2)
}

entity Product {
  title String required
  price BigDecimal required min(0)
  image ImageBlob
}

relationship ManyToOne {
  Blog{user(login)} to User
  Post{blog(name)} to Blog
}

relationship ManyToMany {
  Post{tag(name)} to Tag{post}
}


microservice * with blogBackend

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

​

复制步骤:1-创建文件夹博客2-移动到文件夹博客3-运行: jhipster jdl blog.jdl 4-移动到blogGateWay 5-运行: mvn干净安装

运行: jhpster信息om文件夹博客给我的；

这与J9 (而不是hotspot) vm有关。请参阅https://github.com/reactor/BlockHound/issues/21
