elasticsearch - 重新运行 jhipster 项目时出现 Elasticsearch 错误：创建名称为“userSearchRepository”的 bean 时出错
问题描述
使用 elasticsearch 生成 jhipster 后，我在下面导入了 jdl 文件。

第一次运行没有错误。但是当我重新运行项目时，我得到了一个错误。

当我删除 target/elasticsearch/data/nodes 文件夹中的节点时，它会成功运行，但是当我尝试再次重新运行时，它会失败并出现相同的错误。
我是 jhipster 的新手，我没有做任何代码更改。你能帮忙解决这个问题吗？
解决方案
尝试在终端中运行这两个命令
./mvnw clean
./mvnw
