Error while executing Simple Spring Boot Application in Spring Tool Suite

Question

I have recently installed Spring Tool Suite 4.0.1 on Ubuntu 18.04 and tried to run hello world spring application but it gives the following compile-time error. I have searched on google a lot but cannot find the relevant info. Error:

"Description Resource Path Location Type Archive for required library: '/home/anshul/.m2/repository/org/springframework/spring-test/5.1.2.RELEASE/spring-test-5.1.2.RELEASE.jar' in project 'demo' cannot be read or is not a valid ZIP file"

Answer 1

It looks like the JAR file in your local Maven repository is corrupted. The easiest way to solve this is to completely wipe out the local Maven repo (delete everything under .m2/repository and kick off an Update Maven Project... in STS. That will trigger Maven to download the dependencies again.
