Vaadin 24 构建成功，但从命令行执行失败，未找到 DevModeHandlerManager 实现，但启用了开发服务器

问题描述 投票：0回答：1

我正在尝试运行一个 vaadin 示例测试，我从 Vaadin 的站点启动项目开始，使用 Maven、Spring Boot 和 Apache Tomcat。 在 Eclipse 中运行它，它确实可以毫无问题地打开浏览器并运行页面。 相反，如果我从 Eclipse 设置 Maven Build 运行配置进行构建，我会成功获得一个 JAR 文件。但如果尝试使用 

java -jar filename.jar --trace
运行，则会失败并出现以下错误：

有趣的事情，查看各种线程，了解他们说只需要在 pom.xml 文件中添加 

<frontendHotdeploy>false</frontendHotdeploy>
，我这样做了，但它保留了这个错误。

我的 pom.xml 文件如下，正如您所看到的，有 

<frontendHotdeploy>false</frontendHotdeploy>
，就像他们在这个线程中所说的那样：无法在 Vaadin 24 中构建生产环境 :

我正在使用

Vaadin 24.3.11
，
Tomcat Native 2.0.7
内部
Tomcat 10.1.23
，并且在系统中安装了
Java 17
和
Java 22
（要从命令行运行，必须从Java > 17执行，所以我选择运行frmo爪哇 22）。在 MANIFEST.MF 中我放入：

Manifest-Version: 1.0
Build-Jdk-Spec: 17
Implementation-Title: myexample
Implementation-Version: 1.0.0
Main-Class: com.myexample.application.Application

所以它应该从浏览器检索主类...... 也许我错过了什么，或者我的 

pom.xml
有问题，即使构建成功也无法正常运行？

提前感谢大家！ 干杯! 路易吉

@cfrick 和大家好，经过更多调查，我意识到这与我正确激活它的生产配置文件激活无关。但看起来也缺少添加 

prepare-frontend
插件，因此前端将在编译期间添加到 jar 文件中：

<plugin>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-maven-plugin</artifactId>
    <version>${vaadin.version}</version>
    <executions>
        <execution>
            <goals>
                <goal>prepare-frontend</goal>
