刷maven报错
com.saas:pdf:pom:0.0.1 failed to transfer from http://0.0.0.0/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of maven-default-http-blocker has elapsed or updates are forced. Original error: Could not transfer artifact com.saas:pdf:pom:0.0.1 from/to maven-default-http-blocker (http://0.0.0.0/): Blocked mirror for repositories: saas.com (http://192.168.31.109:8081/service/rest/repository/browse/maven-public/, default, releases+snapshots)
Since Maven 3.8.1 http repositories are blocked.
Possible solutions:
-
Check that Maven pom files do not contain http repository http://192.168.31.109:8081/service/rest/repository/browse/maven-public/
-
Add a mirror(s) for http://192.168.31.109:8081/service/rest/repository/browse/maven-public/ that allows http url in the Maven settings.xml
-
Downgrade Maven to version 3.8.1 or earlier in settings
这个错的原因是：Maven从3.8.1版本开始就禁用了http仓库
简单粗暴的方法，直接降级Maven到apache-maven-3.6.3
