I'm newbie in maven and trying to configure it to build my android project with android-maven-plugin. I have an application.properties file in assets directory which contains different application settings. And i want to obtain this values from my pom. In properties file i define one property as

myFilteredProperty=${helloFromPOM}

and also define the same property in POM:

    <properties>
        <helloFromPOM>MY PROPERTY</helloFromPOM>
    </properties>

Switched on filtering on assets dir

<build>
    ...
    <resources>
        <resource>
            <directory>${project.basedir}/assets</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    ...
</build>

And configure recources plugin as in samples for android-maven-plugin

        <plugin>
            <artifactId>maven-resources-plugin</artifactId>
            <executions>
                <execution>
                    <phase>initialize</phase>
                    <goals>
                        <goal>resources</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

But when i'm trying to show Toast in my application with this property i see ${helloFromPOM} instead MY PROPERTY.

In my target directory which generated by maven i see this properties file in two places:

  • /target/generated-sources/combined-assets/assets/application.properties
  • /target/myapp-0.0.1-SNAPSHOT.apk\application.properties

First is wrong, it contains ${helloFromPOM} instead MY PROPERTY. Second, inside the apk file is correct. But when i install this apk on the device it show me wrong value ${helloFromPOM}.

What did i do wrong?

EDIT

Thanks for answer, I tryed it, but get this error:

When i comment <resourceDirectory>${project.build.directory}/filtered-assets</resourceDirectory> in POM, build finishing successfull, but it doesn't use filtered assests.

Also i try to execute this cmd.exe /X /C ""C:\Program Files\Android\android-sdk\platform-tools\aapt.exe" package -m -J D:\projects\myapp\target\generated-sources\r -M D:\projects\myapp\AndroidManifest.xml -S D:\projects\myapp\target\filtered-assets --auto-add-overlay -A D:\projects\myapp\assets -I "C:\Program Files\Android\android-sdk\platforms\android-8\android.jar"" in my command line and get this error: invalid resource directory name: D:\projects\myapp\target\filtered-assets/application.properties. Wrong slash instead back-slash after filtered-assets. Changing <resourceDirectory>${project.build.directory}/filtered-assets</resourceDirectory> to <resourceDirectory>${project.build.directory}\filtered-assets</resourceDirectory> also doesn't help.

P.S. my plugins section looks like this

   <plugin>
        <artifactId>maven-resources-plugin</artifactId>
        <executions>
            <execution>

Now it works, i change <resourceDirectory>${project.build.directory}/filtered-assets</resourceDirectory> to <assetsDirectory>${project.build.directory}/filtered-assets</assetsDirectory>. Results POM:

    <myProperty>MY PROPERTY!!!!111</myProperty>
</properties>

    <resources>
        <resource>
            <directory>${project.basedir}/assets</directory>
            <filtering>true</filtering>
