Eclipse not recognizing Maven dependent Springframework JAR files

Question

I am trying to compile a java program, can see build is completing successfully. But if i open java program can see errors in java springframework dependence package imports. Though having those jars in the lib folder, getting the error.

Tried following commands,

mvn clean install
mvn package -P local -Dmaven.test.skip=true

It is building the jar.

But not resolving the jar issues. Then i tried giving.

mvn eclipse:eclipse 

Getting below error messages. I can see the dependent jars again in the paths mentioned in the error but still facing the issue.

Any pointers will be highly helpful.

Answer 1

Seems that some artifacts related to eclipse maven plugin are currupted in local maven repo.

So,

1. Delete the entire .m2 folder. (You can also try deleting just org folder in .m2 first to see if it works)
2. Fire mvn clean install -U
3. Fire mvn eclipse:eclipse

Btw, rather than firing eclipse:eclipse you can directly import a maven project in eclipse through File -> Import -> Existing Maven projects.
