如何創建Maven構建配置文件來有條件地複製文件？

Question

我新來Maven和我想創建的pom.xml以建立不同的使用環境配置文件

戰爭文件，所以我創建的構建目標

<build> 
<finalName>myacct_okc</finalName> 
<resources> 
    <resource> 
    <directory>src/main/java</directory> 
    <excludes> 
     <exclude>**/*.java</exclude> 
    </excludes> 
    </resource> 
    <resource> 
    <directory>src/main/resources</directory> 
    </resource> 
    <resource> 
    <directory>config/${environment}</directory> 
    </resource> 
</resources> 
</build> 

然後創建的配置文件爲每個環境

<profiles> 
<profile> 
    <id>local</id> 
    <activation> 
    <activeByDefault>false</activeByDefault> 
    </activation> 
    <properties> 
    <environment>local</environment> 
    </properties> 
</profile> 
<profile> 
    <id>jboss</id> 
    <properties> 
    <environment>jboss</environment> 
    </properties> 
</profile> 
<profile> 
    <id>dev</id> 
    <properties> 
    <environment>dev</environment> 
    </properties> 
</profile> 

和我創建一個config文件夾中的每個ENV

project root 
|-- src 
| |-- main 
| | |-- java 
| | |-- resources 
| | | |-- config.xml 
| | | +-- config.properties 
| | |-- webapp 
| | | |-- META-INF 
| | | | +--context.xml 
| | |-- config 
| | | |-- local 
| | | | |--config.properties 
| | | | +--config.xml 
| | | |-- jboss 
| | | | |--config.properties 
| | | | +--config.xml 
| | | +-- dev 
| | | | |--config.properties 
| | | | +--config.xml 
+--pom.xml 

現在，當我運行這個pom.xml中與例如任何個人資料jboss，config/jboss文件夾的文件不會被複制（或者我的意思是src/main/resources中的文件沒有被替換）。

當我啓用了調試上Maven構建我可以看到越來越執行復制。

[DEBUG] resource with targetPath null 
directory C:\Projects\workspace\myaccount_build_4\myaccount\config\jboss 
excludes [] 
includes [] 
[DEBUG] ignoreDelta true 
[INFO] Copying 2 resources 
[DEBUG] file config.xml has a filtered file extension 
[DEBUG] copy C:\Projects\workspace\myaccount_build_4\myaccount\config\jboss\config.xml to C:\Projects\workspace\myaccount_build_4\myaccount\target\classes\config.xml 
[DEBUG] file config.properties has a filtered file extension 
[DEBUG] copy C:\Projects\workspace\myaccount_build_4\myaccount\config\jboss\META-INF\config.properties to C:\Projects\workspace\myaccount_build_4\myaccount\target\classes\META-INF\config.properties 

但它並沒有替代文件。這些文件仍然來自src/main/resources。

Maven的版本是3.0.4

有人可以幫助我什麼，我做錯了什麼？

我已經看過這個question。這提供了一個解決方案，但我想重寫文件，而不是排除它們，然後複製。

它的工作我添加filtering= true

<build> 
<finalName>myacct_okc</finalName> 
<resources> 
<resource> 
    <directory>src/main/java</directory> 
    <excludes> 
    <exclude>**/*.java</exclude> 
    </excludes> 
</resource> 
<resource> 
    <filtering>true</filtering> 
    <directory>src/main/resources</directory> 
</resource> 
    <resource> 
    <filtering>true</filtering> 
    <directory>config/${environment}</directory> 
    </resource> 
    </resources> 
</build>

我相信你有你的資源添加到Maven的資源 - 插件，複製資源執行內部。

<plugin> 
    <artifactId>maven-resources-plugin</artifactId> 
    <executions> 
    <execution> 
     <id>copy-config</id> 
     <phase>copy-resources</phase> 
     <goals> 
     <goal>copy-resources</goal> 
     </goals> 
     <configuration> 
     <outputDirectory>${project.build.outputDirectory}</outputDirectory> 
     <resources> 
      <resource> 
      <directory>src/main/java</directory> 
      <excludes> 
       <exclude>**/*.java</exclude> 
      </excludes> 
      </resource> 
      <resource> 
      <directory>src/main/resources</directory> 
      </resource> 
      <resource> 
      <directory>config/${environment}</directory> 
      </resource> 
     </resources> 
     </configuration> 
    </execution> 
    </executions> 
</plugin>
