Replace properties with it's values in pom.xml before putting the pom file into maven repository

Tags:

When installing the project into (local) maven repository, I would like to replace all properties placeholders with their current actual values, is this somehow possible?

All in all I'm trying to create a customizable project version in maven, in order to resolve some problems with the transitive dependencies.

Here is my minimized pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>com.foo</groupId>
<artifactId>T</artifactId>
<version>${custom.version}</version>

<properties>
    <custom.version>TEST</custom.version>
</properties>

<build>
    <resources>
        <resource>
            <directory>${basedir}</directory>
            <includes>
                <include>pom.xml</include>
            </includes>
            <filtering>true</filtering>
            <targetPath>${basedir}</targetPath>
        </resource>
    </resources>
</build>

After "mvn clean install" I would like to have in the local maven repository here "~/.m2/repository/com/foo/T/TEST/T-Test.pom" following contents:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>com.foo</groupId>
<artifactId>T</artifactId>
<version>TEST</version>

<properties>
    <custom.version>TEST</custom.version>
</properties>

<build>
    <resources>
        <resource>
            <directory>doesn't matter</directory>
            <includes>
                <include>pom.xml</include>
            </includes>
            <filtering>true</filtering>
            <targetPath>doesn't matter</targetPath>
        </resource>
    </resources>
</build>

So the ${custom.version} placeholder should be replaced by it's current value "TEST", before installing the project into maven repository.

But all I get - is an empty file, even in the current project directory, probably because the file is locked and maven can't override it.

Is there any possibility to install/deploy the pom file with resolved property values?

    </plugins>
</build>

Produces in "~/.m2/repository/com/foo/T/TEST/T-Test.pom" what I want.
