Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Question

I got the following error message when I tried to create a Maven project in eclipse. Many have posted about proxies in settings.xml file and also flush the .m2 folder forcin

Answer 1

There could be multiple reasons, i fixed with following steps:

1. delete .m2 folder and re launch eclipse. (Find m2 folder in windows: c:\Users\Your_User_Name\ .m2 or to search in Mac : ~/.m2
2. make sure settings.xml is configured as #JustinBieber mentioned.
3. provide settings.xml path in eclipse (windows->preferences->maven->user settings) User Settings must locate settings.xml file.

save changes and relaunch the eclipse..!! it should work.
