带有 maven- assembly-plugin 的多个文件 --> “已添加，跳过”

Question

我需要在按环境的 tar 包中创建多个 tar 文件。

每个不同的环境都有一个包含唯一文件“environment.properties”的文件夹，因此我必须将项目内容与每个环境的environment.properties 文件合并：RC、BC、PROD。

我使用 maven- assembly-plugin 来执行此操作，因此有 3 个与该程序集类似的程序集描述符，具有不同的“id”：

<assembly
    xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
    <id>pack-content-rc</id>
    <includeBaseDirectory>false</includeBaseDirectory>
    <formats>
        <format>tar</format>
    </formats>
    <fileSets>
        <fileSet>
            <outputDirectory>/definitions</outputDirectory>
            <directory>definitions</directory>
            <includes>
                <include>*.*</include>
            </includes>
            <excludes>
                <exclude>.*</exclude>
            </excludes>
        </fileSet>
        <fileSet>
            <outputDirectory>/library</outputDirectory>
            <directory>library</directory>
            <includes>
                <include>*.*</include>
            </includes>

                <exclude>.*</exclude>
            </excludes>
        </fileSet>
        <fileSet>
            <outputDirectory>/messages</outputDirectory>
            <directory>messages</directory>
            <includes>
                <include>*.*</include>
            </includes>
            <excludes>
                <exclude>.*</exclude>
            </excludes>
        </fileSet>
        <fileSet>
            <outputDirectory>/templates</outputDirectory>
            <directory>templates</directory>
            <includes>
                <include>**/*</include>
            </includes>
            <excludes>
                <exclude>.*</exclude>
            </excludes>
        </fileSet>
        <fileSet>
            <outputDirectory>/variables</outputDirectory>
            <directory>variables</directory>
            <includes>
                <include>*.*</include>
            </includes>
            <excludes>
                <exclude>.*</exclude>
            </excludes>
        </fileSet>
        <fileSet>
            <outputDirectory>/variables</outputDirectory>
            <directory>target/escape/rc</directory>
            <includes>
                <include>*.*</include>
            </includes>
        </fileSet>      
    </fileSets>
</assembly>

插件的 Maven 配置为：

...
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2.2</version>
<executions>
    <execution>
        <id>make-assembly</id>
        <phase>package</phase>
        <goals>
            <goal>single</goal>
        </goals>
        <configuration>
            <descriptors>
                <descriptor>pack-content-rc.xml</descriptor>
                <descriptor>pack-content-bc.xml</descriptor>
                <descriptor>pack-content-prod.xml</descriptor>
            </descriptors>
        </configuration>
    </execution>
</executions>
...

输出日志为：

问题是 3生成的文件具有相同的environment.properties 文件，确切地说是第一个文件，所以我最终得到了3 个完全相同的包的文件。

我假设组装过程使用一个目录来组成 tar，因此它复制第一个文件，对于第二个描述符，该文件已经存在......

有没有办法避免这种情况发生？在运行每个描述符之前进行一些清理？ 我应该使用 maven-ant-run 插件还是类似的东西？

谢谢！

Answer 1

已添加，跳过 的事情首先出现在插件的 2.2 版本中，您可以尝试 v2.1。

Answer 2

通常，一个 Maven 工件意味着一个输出文件。也许为每个 tar 制作 3 个独立的 Maven 模块更有意义。此外，它还提供了更多的灵活性。
