Yaml File Scanning Java

I'm trying to run a maven project written in intellij idea 2020.2.1.

I run into this error:

org.yaml.snakeyaml.scanner.ScannerException: while scanning for the next token
found character '@' that cannot start any token. (Do not use @ for indentation)
in 'reader', line 3, column 15:
    artifact: @project.artifactId@
              ^
at org.yaml.snakeyaml.scanner.ScannerImpl.fetchMoreTokens(ScannerImpl.java:420)
at org.yaml.snakeyaml.scanner.ScannerImpl.checkToken(ScannerImpl.java:226)

There are similar questions (here, or here ) but none has solved my problem.
