Maven install error after deleting .m2 folder

Question

I was instructed to delete the .m2 folder as I had a problem with one of the project dependencies but now when I tried to Maven > Clean, then Maven > Install the application I get the following error.

I've tried re-running Maven > Clean, Maven Install several times (as sometime it works this way) but no use. I still get the same error message.

Can someone please advice me how to resolve this problem?

Answer 1

The whole problem resided in that I was right clicking on project folder, selecting Maven > Clean, then Maven > Install. When I right clicked on pom.xml and selected Maven > Install everything worked just fine.

Answer 2

Did you also move the location of the maven repository?

Some maven versions had some trouble with whitespaces in path names. So you may try to change the location in settings.xml - then a mvn clean install should re-download everything.

Maybe some of those artifacts are re-downloaded but corrupt? I would then just delete them again and retry. Maybe the jars are HTML files from a proxy?

You can also execute mvn dependency:go-offline - this will download also plugins and everything else required to build the project.

Answer 3

just create .m2 folder and run clean install command.
