java - 在插件运行之前运行插件执行

Question

我正在使用Spotify's docker-maven-plugin将我的一项服务打包到 Docker 容器中。该镜像是通过执行mvn docker:build创建的。我遇到的问题是我需要运行一些 Maven 目标才能将所有内容放在预期的位置，例如将传递依赖闭包复制到 target/ 目录中。我有以下 POM 文件:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>2.10</version>
    <executions>
      <execution>
        <id>copy-dependencies</id>
        <configuration>
          <outputDirectory>${project.build.directory}/lib</outputDirectory>
          <overWriteReleases>false</overWriteReleases>
          <overWriteSnapshots>false</overWriteSnapshots>
          <overWriteIfNewer>true</overWriteIfNewer>
          <includeScope>runtime</includeScope>
          <includeScope>compile</includeScope>
        </configuration>
      </execution>
    </executions>
  </plugin>
  <plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.2.11</version>
    <configuration>
      <imageName>${project.name}-image</imageName>
      <baseImage>java</baseImage>
      <entryPoint>["java", "-jar", "/runtime-environment/lib/${project.build.finalName}.jar", "-classpath", "/runtime-environment/lib/*"]</entryPoint>
      <resources>
        <resource>
          <targetPath>/runtime-environment/lib/</targetPath>
          <directory>${project.build.directory}</directory>
          <include>${project.build.finalName}.jar</include>
        </resource>
        <resource>
          <targetPath>/runtime-environment/lib/</targetPath>
          <directory>${project.build.directory}/lib</directory>
          <include>**/*</include>
        </resource>
      </resources>
    </configuration>
  </plugin>

如何仅在运行 docker:build 之前运行 copy-dependency？

答案是here 。通过添加 executions 部分将 docker:build 目标绑定(bind)到 package 阶段，并运行 package 目标而不是 docker:build

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.2.11</version>
    <configuration>
      <imageName>${project.name}-image</imageName>
      <baseImage>java</baseImage>
      <entryPoint>["java", "-jar", "/runtime-environment/lib/${project.build.finalName}.jar", "-classpath", "/runtime-environment/lib/*"]</entryPoint>
      <resources>
        <resource>
          <targetPath>/runtime-environment/lib/</targetPath>
          <directory>${project.build.directory}</directory>
          <include>${project.build.finalName}.jar</include>
        </resource>
        <resource>
          <targetPath>/runtime-environment/lib/</targetPath>
          <directory>${project.build.directory}/lib</directory>
          <include>**/*</include>
        </resource>
      </resources>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>build</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
