在IDEA中新建一个SpringBoot项目时报错
Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.6.7 from https://maven.aliyun.com/nexus/content/repositories/central/ was cached in the local repository, resolution will not be reattempted until the update interval of alimaven has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.6.7 from/to alimaven (https://maven.aliyun.com/nexus/content/repositories/central/): java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
网上查，试过了在Maven的setting.xml中注释掉镜像-----未解决
也能够进入阿里云仓库，网络正常
也忽略了证书验证打包
然后看了下上面报错的内容
其中有was cached in the local repository，猜想可能是因为之前使用过2.3.4，导致org.springframework.boot包下已有文件
于是删除org.springframework.boot下的所有文件，再重新加载Maven项目就解决了
