我们有一个第三方的罐子放在内部的手工作坊里.我们必须将其包装为docker图像并持久化在docker注册表中.我们已经有了CI流程来构建一个Maven项目，并用docker包装和部署它.但在这种情况下，不需要额外的Java构建过程，因为它是一个可运行的第三方JAR.
我知道作为CI步骤的一部分，我们可以这样做，然后继续对接构建
mvn dependency:copy -Dartifact=<org:artifact:version> -DoutputDirectory=<Path>/target
但这需要一个定制的CI步骤来适应这一点.QN:有没有什么方法可以避免这个特殊的CI步骤，比如使用虚拟包装器pom.xml来下载第三方JAR并将其作为构建输出.
不嫁给maven，它也可以gradle.
"复制"部分看起来微不足道:您只需要将相应的maven-dependency-plugin配置添加到pom.xml，并将适当的生命周期阶段分配给copy目标，例如，下面的配置:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<goals>
<goal>copy</goal>
</goals>
<phase>prepare-package</phase>
<configuration>
<artifactItems>
<artifactItem>
<groupId>tld.group</groupId>
<artifactId>artifact</artifactId>
<version>version</version>
<outputDirectory>${project.build.directory}</outputDirectory>
<destFileName>copy-of-artifact.jar</destFileName>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
导致maven在构建生命周期期间将所需的jar复制到目标目录中.
至于"将第三方jar标记为构建输出"部分，有几个选项:
基本上，您可以将unpack个第三方JAR放入类目录，并要求maven-jar-plugin不创建 list :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<useDefaultManifestFile>true</useDefaultManifestFile>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>unpack</id>
<goals>
<goal>unpack</goal>
</goals>
<phase>prepare-package</phase>
<configuration>
<artifactItems>
<artifactItem>
<groupId>tld.group</groupId>
<artifactId>artifact</artifactId>
<version>version</version>
<outputDirectory>${project.build.directory}/classes</outputDirectory>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
Ii.另一种 Select 是通过禁用maven-jar-plugin并使用gmavenplus-plugin修改项目状态来欺骗maven构建:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>default-jar</id>
<phase>none</phase>
</execution>
</executions>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<goals>

</goals>
<phase>prepare-package</phase>
<configuration>

</artifactItem>

</configuration>
