Question

I am using Intellij Idea and i had created a simple maven project but when i create a jar file and make it run on the terminal it shows me error :
"no main manifest attribute, in target/JMS-1.0-SNAPSHOT.jar"
My pom.xml is :
<?xml version="1.0" encoding="UTF-8"?>
http://maven.apache.org/xsd/maven-4.0.0.xsd">
4.0.0
<groupId>JMS</groupId>
<artifactId>JMS</artifactId>

Not sure what you are trying
But you can add manifest to jar see https://maven.apache.org/shared/maven-archiver/examples/classpath.html
i.e in plugin you need to specify tag true
sample code
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.6</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
<classpathPrefix>../../../../../..</classpathPrefix>
<classpathLayoutType>repository</classpathLayoutType>
<mainClass>com.MainClass</mainClass>
</manifest>
<manifestEntries>
<Implementation-Build>1</Implementation-Build>
<Implementation-Version>1.2</Implementation-Version>
</manifestEntries>
</archive>
</configuration>
</plugin>
