未找到项目“org.springframework.boot:spring-boot-starter-parent:2.6.0-SNAPSHOT”

Question

I am trying to create a spring boot project in IntelliJ Idea. I tried creating a project from Spring initializr. But when I unzip it and run it on my IDE, it keeps repeating the same error:

Project 'org.springframework.boot:spring-boot-starter-parent:2.6.0-SNAPSHOT' not found

Tried using other versions of Spring Boot, but still the same error. I have also tried solutions provided on other posts earlier, but none of them work for me.

my pom.xml file

Answer 3

Try to clean your local maven repository. Mine was corrupted and the following lines solved the problem :

rm -rf ~/.m2/repository
rm -rf ~/.m2/wrapper
