[application使用@符合问题：'@' that cannot start any token. (Do not use @ for indentation)][application_ that cannot start any token. _Do not use _ for indentation]

在application配置文件中使用@出现异常：

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@

      app:
        name: @project.artifactId@
        encoding: @project.build.sourceEncoding@
        java:

解决方案，用单引号或双引号将@@之间的内容包起来：
