Doing "multiple" filters

[Ian Rowlands <Ia...@sro.vic.gov.au>]

Just wondering what is the best way to do "multiple" filters over a set of
files.  The context of the question is:

I have a set of configuration files, and 6 different environments they
could be deployed in.  There is one properties file for each environment.
I'd like to generate the configuration files for all of the environments
during the build, stored in different sub-directories.  Then when I deploy,
I'll extract the set of files which is appropriate and deploy them.  But I
need to have the files for all environments upfront.

>From my understanding of maven filtering, I can only filter the files once.

Any ideas?


Regards,

Ian Rowlands

Hi Ian,

[Warning: Following is untested.]

I don't know about the best way, but I think you should be able to set
up an <execution> for each of the filterings you want to do, something like:

<build>
  ...
  <plugins>
    ...
    <plugin>
      <artifactId>maven-resources-plugin</artifactId>
      <executions>
        <execution>
          <id>one</id>
          <goals><goal>resources</goal></goals>
          <configuration>
            <resources>
              <resource>
                ...  <!-- same syntax as <build><resources>? -->
              </resource>
            </resources>
            <filters>
              <filter>
                ...  <!-- same syntax as <build><filters>? -->
              </filter>
            </filters>
            <outputDirectory>
              ${project.build.outputDirectory}/one
            </outputDirectory>
          </configuration>
        </execution>
        <execution>
          <id>two</id>
          ...
        </execution>
        ...
      </executions>
    </plugin>
    ...
  </plugins>
</build>
