Question

我正在使用Spotify's docker-maven-plugin将我的一个服务打包到Docker容器中。通过执行mvn docker:build创建图像。我遇到的问题是我需要运行一些Maven目标，以便将所有内容放在预期的位置，例如将传递依赖关系复制到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>

如何在copy-dependencies运行之前运行docker:build？

Answer 1

答案是here。通过添加docker:build部分将executions目标绑定到包阶段，然后运行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>

Answer 2

关于您对dependency-plugin的使用：您的find(strncmp(cellname,'B_1W',4) & ... cellfun(@(x)str2double(x(6:9))<5434,cellname) & ... cellfun(@(x)str2double(x(11:14))>5436,cellname))嵌套在<configuration>之下，这使您的配置仅在标准maven构建生命周期的一个或多个阶段内可用。

我的猜测如下：

1）将您的依赖项插件<executions>放在与您的docker-maven-plugin相同的级别上（直接在<configuration>下）。

2）运行<plugin>

如果有效，请告诉我。

在插件运行之前运行插件执行
