I am using Mac Sierra. I deleted /Users/<username>/Library/Application Support/Postman/ directory, It solved the problem.

How to include custom library into maven local repository?

Format :

1. mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>

Ex :
mvn install:install-file -Dfile=/Users/administrator/IdeaProjects/extlib/MSDKCodeAssist.jar  -DgroupId=MSDKCodeAssist  -DartifactId=MSDKCodeAssist  -Dversion=1.0 -Dpackaging=jar
