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@
代码：
info:
app:
name: @project.artifactId@
encoding: @project.build.sourceEncoding@
java:
source: @java.version@
target: @java.version@
解决方案，用单引号或双引号将@@之间的内容包起来：
info:
app:
name: "@project.artifactId@"
encoding: ‘@project.build.sourceEncoding@‘
java:
source: ‘@java.version@‘
target: ‘@java.version@‘
application.yml使用@符合问题：'@' that cannot start any token. (Do not use @ for indentation)
