How to run a Maven jar project from eclipse without tomcat

If you just created a Maven project of package type jar and wondering how to run the jar from Maven command without deploying it to Tomcat or executing the jar using run time then you simply add the below plugin code that is highlighted in your under your pom.xml build -> plugins tag,

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>

	<groupId>code2care</groupId>
	<artifactId>csvexample</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>csvexample</name>
	<url>http://maven.apache.org</url>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>com.opencsv</groupId>
			<artifactId>opencsv</artifactId>
			<version>4.1</version>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.5.1</version>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
				</configuration>
			</plugin>

			<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>exec-maven-plugin</artifactId>
				<version>3.0.0</version>
				<configuration>
					<mainClass>code2care.csvexample.App</mainClass>
				</configuration>
			</plugin>
		</plugins>
	</build>

</project>

Note: the mainClass tag should contain the package to your main class.

Now to run the code in eclipse, all you need to do is under your maven configuration under goal ass exec:java (or clean build exec:java)
