How to define a profile in gradle like maven to replace properties

Question

In my project, i use a profile that changes a property defined in a .pom file. That property is replaced on a file inside of a project. I want to migrate to gradle but i didn't know how to fully convert.

My question is, how to convert this to gradle?

    </build>

    <properties>
        <key.test>jdbc/test</key.test>
    </properties>

    <profiles>
        <profile>
            <id>wildfly</id>
            <properties>
                <key.test>java:/jdbc/test</key.test>
            </properties>
        </profile>
    </profiles>

</project>

On my project, there is a file with a content like this:

<jta-data-source>${key.test}</jta-data-source>

Thank you

Maven-like profiles with gradle :

Create build files for each Maven profile you had in the project root: profile-default.gradle and profile-wildfly.gradle. Then declare your key.test property in those files.

Next, add a condition similar to the following to the main build file:

if (!hasProperty('buildProfile')) ext.buildProfile = 'default'
apply from: "profile-${buildProfile}.gradle"

When you want to build with your wildfly profile call :

gradle -PbuildProfile=wildfly build

Resource filtering with gradle :

Use the ReplaceTokens filter (from ant) within your build.gradle file:

import org.apache.tools.ant.filters.*

processResources {
    filter ReplaceTokens, tokens: [
        "application.version": project.property("application.version")
    ]
}

Then use of @ instead of ${} as token identifier.

<jta-data-source>@key.test@</jta-data-source>
