Maven resource filtering not working - because of spring boot dependency

Question

In a maven project I trying to replace some tokens using maven resource filtering but it does not work. I have some other projects which works but does not work in this single project not sure what is wrong.

The property files is in location /src/main/resources/my.properties

I tried different maven commands as below but does not work.

mvn clean install
mvn clean install resources:resources

my.properties

### Spring boot properties
jdbc.url=${jdbc.url}
ldap.domain=${ldap_domain}
ldap.url=${ldap_url}

</project>

Update:-

I figured out this problem is caused due to the spring boot dependency. If I comment the <parent> section and other spring boot dependencies, then it works fine and able to replace the token. But still not sure how to fix this by keeping spring boot.

Seems this is a defect in spring boot https://github.com/spring-projects/spring-boot/issues/980 — Jay, Apr 08 '16 at 15:12

At last found the answer from the link in my comments. As this is a spring boot application ...special case... the notations should be

@xxxxx@  instead of ${xxxxx}

So my property file would be as below

### Spring boot properties
jdbc.url=@jdbc.url@
ldap.domain=@ldap_domain@
ldap.url=@ldap_url@

You have more information about that in https://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html – pedrocgsousa Jan 19 '17 at 13:22

Just to keep people from hunting, this was changed in SB 1.3.0. Here are the https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-1.3-Release-Notes#maven-resources-filtering – mdo123 Jul 06 '17 at 21:59

I'm using @ but still not working. I'm trying to inject a property during the build. mvn clean install -DsecretProperty=hello and have a property in my property file value.from.file=@secretProperties@ what I got when I run my Spring boot application is this -> @secretProperties@ – Ahmed Aziz Dec 01 '20 at 20:40
I can'be belive this is still an issue in Spring Boot 2.5.4. But it is. – jediz Sep 13 '21 at 07:35
