adding jar libraries into jar file

Question

I am doing a maven project. Everything is fine when compiling and running my project in an idea, but whenever I create jar file, my external jar files in web/lib/ cannot be copied into the jar file. Why this occurs ? Can I insert my all files into the jar file ?

You can use the jar-with-dependencies descriptor of Maven Assembly Plugin to achieve this.

You need to use Maven Assembly plugin something like this:

</project>
 ...
 <build>
      ...
      <plugins>
          <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.2</version>
            <configuration>
              <archive>
                <manifest> <!-- requires for executable Jar -->
                  <mainClass>org.my.main.MainClass</mainClass>
                </manifest>
              </archive>
              <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef> <!-- final Jar will have this text appended -->
              </descriptorRefs>
            </configuration>
        <executions>
          <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- append to the packaging phase. -->
            <goals>
              <goal>single</goal> <!-- goals == mojos -->
            </goals>
          </execution>
        </executions>
      </plugin>
      ....
      </plugins>
  </build>
</project>

I have already used this plugin. I am using Symmetricds jar files in my project, but I could not see these jar files in the jar file. Symmetricds jar files in web/lib directory. – olyanren Feb 15 '11 at 08:33
@Muhammed Yüce, Are these Symmetricds jar files added as dependencies in your pom.xml? – Nishant Feb 15 '11 at 08:42
NO, they did not. Because these jar files are special to Symmetric Ds which provides synchronization between two database. I just want to add the folder which contains jar files, into executable jar file. – olyanren Feb 15 '11 at 08:48
@Muhammed Yüce -- So, you need to add those Jars as dependencies. Since they are not publicly available, you need to install them in your local repo like `mvn install:install-file -Dfile= -DgroupId= -DartifactId= -Dversion= -Dpackaging=jar` and add it to dependencies list. They will be available in the package. see here http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html you can also use one-jar to manually create a jar bundle see here http://one-jar.sourceforge.net/ – Nishant Feb 15 '11 at 09:15
My folder is under src folder. This link shows how we can add src folder : http://stackoverflow.com/questions/4831831/maven-to-copy-jar-when-adding-dependencies – olyanren Feb 15 '11 at 09:19

            <manifest>
                <addClasspath>true</addClasspath>
                <mainClass>com.gui.launcher.LauncherMain</mainClass>
            </manifest>
        </archive>
 
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
 
    <executions>
        <execution>
            <id>make-assembly</id>
            <!-- this is used for inheritance merges -->
            <phase>package</phase>
            <!-- append to the packaging phase. -->
            <goals>
                <goal>single</goal>
                <!-- goals == mojos -->
