java - Yaml 文件上的 Maven ArcheType 过滤器

Question

构建我的 Archetype 时，我在解析 yaml 文件时收到错误

我已经以这种方式在yaml的archetype-metadata.xml上设置了fileSet

<fileSet filtered="true" encoding="UTF-8">
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.yml</include>
            </includes>
        </fileSet>

这是我的 yaml 文件

spring:
 application:
  name: ${applicationName}-service
logging:
 pattern:
  console: ""
management:
  security:
    enabled: false
server:  
  port: ${PORT:4001}

这是我的 ArcheType 的清理并安装错误

 org.apache.velocity.exception.ParseErrorException: Encountered ":4001}" at archetype-resources/src/main/resources/bootstrap.yml[line 11, column 15]
Was expecting one of:
    "[" ...
    "}" ...

Velocity 将尝试在 $ (美元符号)之后获取变量，因此我建议您欺骗 Velocity 来忽略它，然后您的 Spring 将获得所需的输出 ${PORT:4001} 速度完成后转换模板。

#set ( $dollarSign = "$")
port: $dollarSign{PORT:4001}

应该是 ${dollarSign}{PORT:4001}
