I was able to reproduce, this is the stacktrace :

while scanning for the next token
found character '@' that cannot start any token. (Do not use @ for indentation)
in 'reader', line 3, column 14:
maven.value: @project.artifactId@
             ^
at org.yaml.snakeyaml.scanner.ScannerImpl.fetchMoreTokens(ScannerImpl.java:421)
at org.yaml.snakeyaml.scanner.ScannerImpl.checkToken(ScannerImpl.java:226)

The problem comes from the file itself :

instead of :

maven.value: @project.artifactId@

it should be :

maven.value: "@project.artifactId@"
