If anyone has the answer please write it down in the comment and thanks in advance.

There's no configuring for Java 7.
You must use Java 8.
We're going to be moving up to minimum Java 11 in early 2021, although it should work now

I am trying to run jira application on my local machine with atlas-run and atlas-debug command. But i have a build failure here.

Following are the major versions of JRE the class file is compatible with
Java SE 9 = 53
Java SE 8 = 52
Java SE 7 = 51
Check what version of JAVA does your MAVEN is using mvn -version. You should be using jre 1.7

You didn't mention the Jira version you're running, but the error, as mentioned by ravthiru comes from a Java version mismatch. That is you have to use Java 8 for this to work, at least if you stick to the atlas-run and atlas-debug scripts, which use the mentioned com.atlassian.maven.plugins:maven-amps-dispatcher-plugin:6.2.1
which is a bit odd, as that one is included in the plugin-sdk 6.2.2, maybe you updated the sdk? Would you mind having a look inside atlas-run and double check it's 5.0.3?
That plugin was compiled using Java 8, so you either have to do so too or use an older version of the atlassian-plugin-sdk, which was compiled using Java 7. The 5.x versions should work.
Regarding the failure of running Jira with Java 8: Which version are you running, and what errors does it log?

Also i dont know how to check the output... Is the error normal?

1) Check if your JRE (java version) of your project in your workspace(eg: eclipse properties window) is same as your java version in your machine from which you are running the hadoop jar command.
2) I am assuming that you are submitting the jar as
hadoop jar

Hadoop jars, you need to check them. Make sure all jars are updated (better bring in the latest version for every jar) and compatible with each other. You can find the version dependencies at http://www.mvnrepository.com/

ABRT problem creation: 'success'
i have tried the simple google search but all i can find out is that the program is being compiled using a later version of java and being run with another. however, all the solutions i came across are based on eclipse and i am not using this.
please help!

The error that you are getting because you are using different version of Java. Try down grading to Java 1.7 or Java 1.6 if you are using Java 1.8.
Hope this helps.

It will help you. Its because, your compiler and JVM versions mismatch. Your IDE tools might have options to change Compiler version.

it has only one class.
classname=Server.java
one external library is used name=Bluecove.jar which is used for accessing bluetooth from java.
Ide used=Eclipse
used Eclipse for creating jar,already checked the option "Pacakage required libraries into generated jar"
This Error came while i try to run that same jar in another computer....

It is a problem with the version of the used JRE. See this post for details.
Try
java --version
on both machines.

This error indicates, that your file is not executable with the installed JRE version.
See How to fix java.lang.UnsupportedClassVersionError: Unsupported major.minor version for more info about that.

java.lang.UnsupportedClassVersionError happens because of a higher JDK during compile time and lower JDK during runtime. Make sure the jdk version installed in your laptop is equal or higher than your friend's.
