idea maven打包错误

一：idea language level 总是变成springboot 默认5时，

打包错误：-source 1.5 中不支持 diamond 运算符

plugin添加指定版本配置，如下

二：idea maven 打包报如下错误

Caused by: org.yaml.snakeyaml.scanner.ScannerException: while scanning for the next token
found character '@' that cannot start any token. (Do not use @ for indentation)
 in 'reader', line 7, column 13:
        active: @activatedProperties@

plugin添加配置，如下

注：当打包不报如上错误，启动项目主类时同样报此错，添加以下依赖

        
            org.yaml
            snakeyaml
            your-version

END 完整配置：
