adding spring-boot-starter-parent to project 'corrupts' resourse filtering-CodePudding

I have resource plugin configuration in pom.xml in CLI NON-SPRING app:

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

calling mvn resources:resources successfully replaces all ${variables}.

The project got into state, that it would really genefit from inversion of control, so I'd like to throw spring into action here. Step one, add spring parent:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
<!--    <version>2.7.7</version>-->
    <version>2.6.6</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

not the same command won't substitute variables, resource filtering does not work.

What am I missing?

I know that spring defines some plugins, and if one want to redefine them, he needs to use same ID for example, but I cannot find the root-problem here. (and note: yes, I know I can avoid referencing spring via parent or use weld/cdi instead, but atm I'd like to get working spring with defined parent)

Remembered the cause thanks to writing to stack overflow used a rubber duck (sorry).

It's caused by that variable pattern is different to avoid conflict between spring and maven variables. Spring redefined variable placeholders. What was: ${project.version} before is now @project.version@ or whatever you define, but you cannot use ${} otherwise spring will 'erase' all variables spring should substitute.

Sorry for pointless question. Keeping it, maybe it will help someone in future.

CodePudding user response：

If you are only adding spring for IoC then you don't need to add the whole package. I thing you can get away only with:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>5.4.0</version>
</dependency>

Also the dependency that you have added is used for spring boot projects.
