yml使用@符合問題：'@' that cannot start any token. (Do not use @ for indentation)

在application配置文件中使用@出現異常：

Exception in thread "main" while scanning for the next token
found character '@' that cannot start any token. (Do not use @ for indentation)
 in 'reader', line 4, column 11:
        name: @project.artifactId@

代碼：

info:
  app:
    name: @project.artifactId@
    encoding: @project.build.sourceEncoding@
    java:
      source: @java.version@
      target: @java.version@

解決方案，用單引號或雙引號將@@之間的內容包起來：

info:
  app:
    name: "@project.artifactId@"
    encoding: '@project.build.sourceEncoding@'
    java:
      source: '@java.version@'
      target: '@java.version@'
