How to include system dependencies in war built using maven

Let me try to summarise the options I tried :

<packagingIncludes>${java.home}/lib/jfxrt.jar</packagingIncludes>

This doesn't work! Also, only having the jar name, excludes everything else, so if you are willing to try then try

<packagingIncludes>${java.home}/lib/jfxrt.jar,**/*</packagingIncludes>

Jatin's answer seemed a bit complex and I tried going through the POM again & again to figure out where exactly were the system jars mentioned to be included in WEB-INF POM.

Anyways, I ended up using this solution, which wasn't working at first but after some time and some corrections worked :

I installed the jar in my local repository using the below command :

mvn install:install-file -Dfile="C:\Users\hp\Documents\NetBeansProjects\TwitterAndLoginRadiusMaven\lib\LoginRadius-1.0.jar" -DgroupId=LoginRadius -DartifactId=LoginRadius -Dversion=1.0 -Dpackaging=jar`

After running the above command, I changed the dependency in POM to

<dependency>
   <groupId>LoginRadius</groupId>
   <artifactId>LoginRadius</artifactId>
   <!--<scope>system</scope>-->
   <version>1.0</version>
   <!--<systemPath>${basedir}\lib\LoginRadius-1.0.jar</systemPath>-->
</dependency>

NOTE - See I've commented the system scope & systemPath.

Building the war now, includes this LoginRadius-1.0.jar in WEB-INF/lib

You can configure the war plugin to have all or some jar included or excluded as per your need as mentioned below. Simple & works

           <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <webResources>
                        <resource>
                            <directory>${project.basedir}\lib</directory>
                            <targetPath>WEB-INF/lib</targetPath>
                            <filtering>false</filtering>
                            <includes>
                                <include>**/*.jar</include>
                            </includes>
                            <excludes>
                                <include>**/javax.servlet-api-3.1.0.jar</include>
                            </excludes>
                        </resource>
                    </webResources>
                </configuration>
            </plugin>

If you meant as jar dependencies, then below is a sample pom.xml which takes are needed files and generates a war file:

 <build>
        <defaultGoal>install</defaultGoal>
        <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
        <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
        <outputDirectory>${project.basedir}/target/classes</outputDirectory>
        <testOutputDirectory>${project.basedir}/target/test-classes</testOutputDirectory>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
            </resource>
        </resources>
        <testResources>
            <testResource>
                <directory>${project.basedir}/src/test/resources</directory>
            </testResource>
        </testResources>

If by chance you can't install the third party library to your local repository, due to some silly naming/packaging checks by the third party, you can still add your system scoped dependencies to your final package at build time (at least if you are building a webapp) using the maven-war-plugin where you would need to create a configuration like this.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.2.0</version>
    <configuration>
        <failOnMissingWebXml>true</failOnMissingWebXml>
        <webResources>
            <resource>
               <directory>path/to/lib/in/project</directory>
               <targetPath>WEB-INF/lib</targetPath>
            </resource>
        </webResources>
    </configuration>
</plugin>

Not sure but I believe that the library must be somewhere local to the project's base directory. I tend to create a directory under src/main/ called lib to hold these sorts of 3rd party libs. During build process they are placed in the correct directory and added to the war file.
