Maven:复制没有子目录结构的文件 [英] Maven : copy files without subdirectory structure

问题描述

我正在尝试使用Maven将给定文件夹中包含的所有* .xsd文件移动到另一个文件夹，但没有源子目录结构.

I am trying to use Maven to move all the *.xsd files contained in a given folder to another one, but without the source subdirectory structure.

这是我到目前为止所拥有的:

This is what I have so far:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.3</version>
    <executions>
        <execution>
            <id>move-schemas</id>
            <phase>generate-sources</phase>
            <goals>
                <goal>resources</goal>
            </goals>
            <configuration>
                <outputDirectory>${basedir}/schemas-target</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

...

<resources>
    <resource>
        <directory>${basedir}/schemas-source</directory>
        <includes>
            <include>**/*.xsd</include>
        </includes>
    </resource>
</resources>

而且(几乎)可以正常工作.唯一的问题是，它保留了源子目录的结构，而我需要删除该层次结构并将所有xsd文件放在目标文件夹中.示例:

And it is (almost) working. The only problem is that it keeps the source subdirectory structure, while I need to remove that hierarchy and put all the xsd files in the target folder. Example:

这是我在schemas-source文件夹中拥有的内容:

This is what I have in the schemas-source folder:

schemas-source
 │- current
 │    │- 0.3
 │        │- myfile.xsd
 │- old
      │- 0.2
          │- myfile-0.2.xsd

这是我在schemas-target文件夹中所需要的:

and this is what I'd need in the schemas-target folder:

schemas-target
 │- myfile.xsd
 │- myfile-0.2.xsd

推荐答案

我自己一次又一次地撞到了那个限制.

I banged my head against that restriction myself, again and again.

基本上:我不认为只有Maven的解决方案.您将不得不使用动态的东西，例如

Basically: I don't think there's a maven only solution. You will have to resort to using something dynamic like

• Maven Antrun插件
  将ant任务嵌入到maven中，在本例中为ant 复制任务，类似这样:

• The Maven Antrun Plugin
  Embed ant tasks in maven, in this case an ant copy task, something like this:

<copy todir="${project.basedir}/schemas-target" flatten="true">
    <fileset dir="${project.basedir}/schemas-source">
        <include name="**/*.xsd"/>
    </fileset>
</copy>

GMaven插件 使您可以从pom执行Groovy代码，如下所示:

The GMaven plugin Lets you execute Groovy code from your pom, something like this:

new File(pom.basedir, 'schemas-source').eachFileRecurse(FileType.FILES){
    if(it.name.endsWith('.xsd')){
        new File(pom.basedir, 'schemas-target/${it.name}').text = it.text;
    }
}
