When I got an error saying  archive for required library could not be read   I solved it by removing the JARS in question from the Build Path of the project  and then using  Add External Jars  to add them back in again  navigating to the same folder that they were in    Using the  Add Jars  button wouldn t work  and the error would still be there   But using  Add External Jars  worked

I faced this problem  I had  Archive for required library spring-boot-devtools cannot be read or is not a valid ZIP file  and the solution was like that - 1- determine the dependencies names that have problems for may case it is spring-boot-devtools   2- close eclipse  3- search in your  m2 file on these dependencies by name   4- delete these folders  5- reopen eclipse and let maven rebuild your dependencies again

Indeed IDEs often cache the local repository  Eclipse does something similar  and I have to relaunch Eclipse    One ugly maven behavior you might encounter is that if you declare a dependency before you actually install it  maven will create an empty version of the missing dependency  folder with metadata but no jar   and you will have to manually clean your  m2 repository   Third  an installed archive  jar     can get corrupted  so try to open it with any archive tool  7zip     to test it  and delete the whole folder if the archive is corrupted
