Spring boot parent prevents resources:resources

Marcel :

I have a spring boot maven project with a property file in which I need to replace the property value for spring.cloud.config.server.git.username and spring.cloud.config.server.git.password properties using mvn resources:resources, but the values are not replaced as I expected. To try to find the cause I created a small project that only contains the property file and pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.5.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>demo</groupId>
    <artifactId>resource-demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>resource-demo</name>

    <properties>
        <java.version>1.8</java.version>
        <a.name>placholder</a.name>
    </properties>

    <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>
</project>

Executing mvn resources:resources -Da.name="some name" with the above pom, the ${a.name} is not replaced, but when I remove the spring boot parent from the pom, the ${a.name} is replaced.

Can anyone explain me what I am doing wrong here?

This is the content of the property file:

Hello ${a.name}.

In the documentation it is stated that you have to use @a.name@ instead of ${a.name}.
