Question

Ok I am switching from ant to maven on an android project and wondering if it the following would be easy to implement:

Currently I have a custom build.xml script wh

In Maven, this is called resource filtering, android-maven-plugin support filtering the following resource types:

• AndroidManifest.xml, see this answer.
• assets/, see this answer.
• res/, see below.

Sample res/value/config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<resources>
  <string name="config_server_url">${config.server.url}</string>
</resources>

Sample pom configuration for filtering all xml file under res/ directory:

<build>
  <resources>
    <resource>
      <directory>${project.basedir}/res</directory>
      <filtering>true</filtering>
      <targetPath>${project.build.directory}/filtered-res</targetPath>
      <includes>
        <include>**/*.xml</include>
      </includes>
    </resource>
  </resources>
  <plugins>
    <plugin>
      <artifactId>maven-resources-plugin</artifactId>
      <executions>
        <execution>
          <phase>initialize</phase>
          <goals>
            <goal>resources</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <groupId>com.jayway.maven.plugins.android.generation2</groupId>
      <artifactId>android-maven-plugin</artifactId>
      <extensions>true</extensions>
      <configuration>
        <sdk>
          <platform>10</platform>
        </sdk>
        <undeployBeforeDeploy>true</undeployBeforeDeploy>
        <resourceDirectory>${project.build.directory}/filtered-res</resourceDirectory>
      </configuration>
    </plugin>
  </plugins>
</build>

There are several ways to define the substituted value, you can define them in an external properties file with properties-maven-plugin. For simplicity, I prefer to use Maven profiles and define them in pom.xml, like so:

<profiles>
  <profile>
    <id>dev</id>
    <properties>
      <config.server.url>dev.company.com</config.server.url>
    </properties>
  </profile>
  <profile>
    <id>Test</id>
    <properties>
      <config.server.url>test.company.com</config.server.url>
    </properties>
  </profile>
  <profile>
    <id>Prod</id>
    <properties>
      <config.server.url>prod.company.com</config.server.url>
    </properties>
  </profile>
</profiles>

Then use mvn clean install -Pxxx to build corresponding apk.
