Question

据我了解构建流程：

maven-assembly-plugin构建/target/my-artifact-1.0-SNAPSHOT-jar-with-dependencies.jar
maven-jar-plugin构建/target/my-artifact-1.0-SNAPSHOT.jar（不确定我们为什么需要它）
docker-maven-plugin假定为assemble artifact-with-dependencies /target/my-artifact-1.0-SNAPSHOT-jar-with-dependencies.jar

尽管如此，由于某种原因，它还是拾取了错误的罐子人工制品。

我想念什么？如何运作？

要引用文档，请：

     <descriptorRef>artifact-with-dependencies</descriptorRef>
将添加名称为创建的工件 $ {project.build.finalName}。$ {artifact.extension}和所有jar targetDir（默认为/ maven）中的依赖项。

这不是您想要的。

您想要的是自定义程序集，使其类似于：

<assembly>
 <targetDir>/target</targetDir>
 <inline>
    <fileSets>
      <fileSet>
        <directory>${project.basedir}/target/</directory>
        <outputDirectory>.</outputDirectory>
        <includes>
             <include>project-name-version-classifier-jar-with-dependencies.jar</include> 
         </includes>
         </fileSet>
       </fileSets>
     </inline>
   </assembly>

要点：看一下Jib，如果您正在为Java项目构建映像，它可能会更适合您的需求。

为什么docker-maven-plugin无法拾取正确的jar文件以包含在docker映像中？
