How to run Maven project in Eclipse by importing it from github

Question

I am new to Java and maven I just need to run this https://github.com/att/XACML Maven project.

Any one please give me some guidelines as If I build this in Eclipse I get these errors.
I need to install gpg software as I don't know much about gpg, because I am new to this.

Once that will work, I will need to know how to run:

mvn jetty:run-war

The part of the error message that matters is just above what you posted.
See for instance att/XACML issue 30:

[INFO] --- maven-gpg-plugin:1.5:sign (sign-artifacts) @ att-xacml ---
gpg: signing failed: Inappropriate ioctl for device
gpg: signing failed: Inappropriate ioctl for device

That error was resolved with a Java update, so double-check which Java you are using in your Eclipse.

In the OP's case, the error is:

'gpg.exe' is not recognized as an internal or external command,
operable program or batch file.

That simply means you need to launch Eclipse from a CMD session where gpg.exe is recognized:

gpg.exe --version
gpg (GnuPG) 2.0.29 (Gpg4win 2.3.0)

Check your %PATH% in the CMD:

set PATH

And adjust it accordingly:

set PATH=C:\path\to\gpg;%PATH%

Then launch Eclipse, and in it maven.

The OP adds:

how I am able to access the console of local host?
Like where I can run this command (mvn jetty:run-war) and how.

See "Is there any tool in eclipse to run maven commands directly?": assuming you have m2e (M2Eclipse) already installed with you Eclipse, you will be able to define a maven "run configuration".

See more in "Sonatype: Developing with Eclipse and Maven / 4.2. Running Maven Builds".

For mvn jetty:run specifically, see "how to run a web service maven project on jetty 8 from eclipse?".
