Maven - import local jar to project

Quick solution:

<dependency>
    <groupId>com.example</groupId>
    <artifactId>example-name</artifactId>
    <version>1.0</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/external_libs/MY_JAR_NAME.jar</systemPath>
</dependency>

We just need to:

1. add this dependency to our pom.xml
2. import maven dependency (reimport with intellij IDEA or run mvn clean install command)

Maven - included external JAR lib into WAR

In order to include external JAR library into our WAR we need to add below plugin to pom.xml:

<plugin>
	<artifactId>maven-war-plugin</artifactId>
	<version>2.4</version>
	<configuration>
		<failOnMissingWebXml>false</failOnMissingWebXml>
		<webResources>
			<resource>
				<directory>${project.basedir}/external_libs</directory>
				<targetPath>WEB-INF/lib</targetPath>
				<filtering>false</filtering>
				<includes>
					<include>**/*.jar</include>
				</includes>
			</resource>
		</webResources>
	</configuration>
</plugin>
