i know that maven is included in spring framework, and when i check the directory, the jars are there.

How can I solve this error?

Answer 1

The relevant part of the error message is:

invalid LOC header (bad signature) 

which suggests some binary file being broken, most likely one of the dependencies. If you have a fast Internet connection, just delete your whole maven repository and let maven redownload all the dependencies:

rm -rf ~/.m2/repository/*

Answer 2

From my experience , invalid LOC header (bad signature) is most probably due to the downloaded .jar file is corrupt.

If you have a slow internet connection , instead of deleting the whole Maven repository , you can try to delete the folder containing the problematic jar according to the hints of the errors message (i.e C:\Users\User01\.m2\repository\org\apache\maven\plugins\maven-war-plugin\2.1.1\) . Then use mvn clean install -U to download the dependencies again.
