Spring Boot native：使用多模块 Maven 构建进行编译

Question

我尝试为具有多个 Maven 模块的 Spring Boot 3.0 应用程序编译 GraalVM Native Image。

模块结构如下：

heroes-parent
|- heroes-backend
|- heroes-frontend
|- heroes-webapp

每个子目录是父目录的一个模块

pom.xml 提取：

  <modules>
    <module>heroes-backend</module>
    <module>heroes-frontend</module>
    <module>heroes-webapp</module>
  </modules>

当我尝试使用（参见Spring Boot docs）构建应用程序时：

mvn -Pnative native:compile

它错误（因为父级没有类）：

[ERROR] Failed to execute goal org.graalvm.buildtools:native-maven-plugin:0.9.18:compile (default-cli) on project heroes-parent: Image classpath is empty. Check if your classpath configuration is correct. -> [Help 1]

所以，我尝试先用mvn install构建整个应用程序，然后只用native:compile构建应用程序heroes-webapp

mvn install 
cd heroes-webapp
mvn -Pnative native:compile

但这失败并出现以下错误：

你可以找到source code for the whole application on GitHub。

有没有办法用 Maven 多模块 Spring Boot 3 应用程序构建本机图像？

我发现了问题。 Visual Studio Code 已打开，项目已使用 Extension Pack for Java 加载。这是在 Maven 构建它们时删除了类，这导致了上述错误。
