But in my project explorer :
I am unable to understand that why it is creating a proper maven project every time it shows a red warning mark into my project and as well as in my pom.xml file.

I am fail to understand that why this happening every time to me and my .m2\repository folder is also empty . Please suggest me some steps to fix it and properly run a maven project.

Answer 1

Since i am not behind any proxy so i don't need to worry about the settings.xml file i just deleted .m2 folder and just simply try to create a maven project again
and maven itself downloads the required dependencies automatically.
Hence problem is resolved.

Answer 2

As reputable sources go:
apache/maven PR 38 illustrates you should not define any M2_HOME (not with recent maven versions)
apache-maven/src/bin/mvn shows that, if MAVEN_HOME is not defined, it defaults to where maven is installed.
By deleting your ~/.m2 folder, you have forced Eclipse (through m2e, included in any Eclipse 4.5 or newer), to revert back to a default m2 folder.
It also uses, per FAQ, the default <maven home>/conf/settings.xml
