java - 为什么 docker-maven-plugin 无法获取正确的 jar 文件以包含在 docker 镜像中？

Question

据我了解构建流程:

1. maven-assembly-plugin 构建 /target/my-artifact-1.0-SNAPSHOT-jar-with-dependencies.jar

   <

2. maven-jar-plugin 构建 /target/my-artifact-1.0-SNAPSHOT.jar(不确定我们为什么需要它)

3. docker-maven-plugin 假设为 assemble 带有依赖关系的 Artifact /target/my-artifact-1.0-SNAPSHOT-jar-with-dependencies.jar

然而，出于某种原因，它选择了错误的 jar Artifact 。

我错过了什么？如何让它发挥作用？

要引用文档，:

     <descriptorRef>artifact-with-dependencies</descriptorRef>

will add the created artifact with the name ${project.build.finalName}.${artifact.extension} and all jar dependencies in the the targetDir (which is /maven by default).

这不是你想要的。

我认为你想要的是将程序集自定义为这样的东西:

<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>
