There are several reason to cause this error as below because maven is unable to connect to Maven repository at http://repo1.maven.org/maven2.

      true
      http
      user name  
      password   
      127.56.8.64        
      80                 
      local.net|some.host.com

You don’t need to touch , and sections, unless you really know what are these tags.

After updating this setting restart eclipse and follow the steps in Maven Force update of Snapshot/Releases.

Remove .lastUpdated file

If this problem is not resolved yet got to .m2/repository/ to dependency sub directory and remove .lastUpdate file inside of it or delete complete directory for this particular dependency and again follow the steps in Maven Force update of Snapshot/Releases.

For Example as for above issue directory location showing in exception as

C:\Users\saurabh.gupta1.m2\repository\org
\springframework\spring-expression\5.1.6.RELEASE
