Spring Boot和Vaadin错误构建Java.lang.LuntimeException：无法初始化com.vaadin.flow.spring.vaadinservletcontextinitialializer

Question

在构建应用程序中（mvnw spring-boot：run）我收到此错误：

我尝试使用命令尝试清洁somethinks：

mvnw clean install

或尝试在pom.xml中添加或删除有关vaadin版本：

<vaadin.version>23.0.6</vaadin.version>

没有更改。 也许这是一种涉及的一种，我看不到。 在pom.xml下方。

我该如何解决？

Answer 1

您正在使用的报告-UI插件包含一个名为Flow-Build-Info.json的文件，该文件是应用程序的一部分，但绝不应该在插件中打包。您的应用程序应该读取Flow-Build-Info.json主要来自项目中的目标文件夹，但在您的情况下，它发现并尝试使用插件中的一个。

删除插件应解决问题。询问插件作者修复插件。
