原因解释

mvn版本低了，项目中使用到了下述插件:

application.yml

logging:
  file:
    path: logs
  config: classpath:logback-spring.xml
spring:
  profiles:
    active: @profile.active@

pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <configuration>
    <delimiters>@</delimiters>
    <useDefaultDelimiters>false</useDefaultDelimiters>
    </configuration>
</plugin>

application.yml中使用@来定义不同环境的配置，pom中使用了插件来消除默认的@转义，导致低版本的manen不能正常使用。

解决方案

换用高版本maven，笔者升级到了3.5.4
