Maven程序集插件:包含文件而不占用其路径文件夹 [英] Maven assembly plugin: include file without taking its path folders

问题描述

我正在使用maven-assembly-plugin将依赖项ZIP文件(也由程序集插件生成)中的文件包含到最终发行的ZIP文件中.

I'm using maven-assembly-plugin to include files from a dependency ZIP (also generated with assembly plugin) into a final release ZIP file.

问题是我想从依赖项中选择要获取的文件，但不复制这些文件所在的文件夹路径.只是文件.

The issue is that I want to select which files from the dependency to get, but not copying the folder path where those files are. Just the files.

例如:

<assembly>
    <formats>
        <format>zip</format>
        <format>dir</format>
    </formats>

    <includeBaseDirectory>false</includeBaseDirectory>

    <dependencySets>
        <dependencySet>
            <includes>
                <include>package:artifactId:zip:*</include>
            </includes>
            <outputDirectory>sql/update/01.00.00_to_01.01.00</outputDirectory>
            <unpack>true</unpack>
            <unpackOptions>
                <includes>
                    <include>oracle/update/1_alter_schema.sql</include>
                    <include>oracle/update/2_insert_data.sql</include>
                </includes>
            </unpackOptions>
            <useProjectArtifact>false</useProjectArtifact>
            <useTransitiveDependencies>false</useTransitiveDependencies>
        </dependencySet>
    </dependencySet>
</assembly>

这将复制所需的文件，如下所示:

This copies the required files like this:

• sql/update/01.00.00_to_01.01.00/ oracle/update /1_alter_schema.sql
• sql/update/01.00.00_to_01.01.00/ oracle/update /2_insert_data.sql

• sql/update/01.00.00_to_01.01.00/oracle/update/1_alter_schema.sql
• sql/update/01.00.00_to_01.01.00/oracle/update/2_insert_data.sql

我只想复制没有原始 oracle/update/文件夹的文件，从而得到以下文件夹结构:

I would like to copy just the files without the original oracle/update/ folder, resulting in this folder structure:

• sql/update/01.00.00_to_01.01.00/1_alter_schema.sql
• sql/update/01.00.00_to_01.01.00/2_insert_data.sql

依赖项ZIP包含许多由不同项目使用的文件，因此在这里区分oracle和sql-server文件的结构是有意义的，但是对于这种分发，我不需要那些文件夹，而仅是文件.

The dependency ZIP contains many files used by different projects, therefore the structure to differentiate oracle from sql-server files makes sense there, but for this distribution I don't need those folders, just the files.

有人知道使用maven-assembly-plugin是否可能?

Does somebody knows if this is possible with maven-assembly-plugin?

非常感谢！

推荐答案

它应该通过拆分依赖项解压缩和文件汇编来工作.

It should work by splitting the dependency unzipping and the file assembly.

在执行组装工作之前，配置 dependency-plugin 以解压缩所需的依赖项:

Configure the dependency-plugin to unpack the desired dependency before performing the assembly work:

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <configuration>
        <includeArtifactIds>project-sql</includeArtifactIds>
        <outputDirectory>${project.build.directory}/extract</outputDirectory>
        <includes>oracle/update/1_alter_schema.sql,oracle/update/2_insert_data.sql</includes>
    </configuration>
    <executions>
        <execution>
            <id>unpack-sql</id>
            <phase>prepare-package</phase>
            <goals><goal>unpack-dependencies</goal></goals>
        </execution>
    </executions>
</plugin>

然后，在您的 assembly-distribution.xml 中，仅从子目录进行组装:

Then, in your assembly-distribution.xml, just assemble from the sub-directory:

<?xml version="1.0" encoding="UTF-8"?>
<assembly
    xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
    <id>distribution-${project.version}</id>

    <formats>
        <format>zip</format>
        <format>dir</format>
    </formats>

    <includeBaseDirectory>false</includeBaseDirectory>

    <fileSets>
        <fileSet>
            <directory>${project.build.directory}/extract/oracle/update</directory>
            <outputDirectory>sql/update/01.00.00_to_01.01.00</outputDirectory>
        </fileSet>
    </fileSets>
</assembly>
