我有以下(非常(简单的pom.xml：

以及以下(非常(简单的项目结构：

\message_generator\src\main\scala\com\message\generator\MessageGeneratorMain.scala

运行时 mvn 清理编译程序集：单个

我得到了一个带有依赖项的 jar，但我自己的代码(3 个类，包括 Main 类(不包含在最终的 jar 中。

你必须包含Maven Scala插件才能在src/main/scala中捕获scala代码

<build>
<plugins>
<plugin>
<groupId>org.scala-tools</groupId>
<artifactId>maven-scala-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
