Export as an executable jar file

Question

I have an maven eclipse project which I want to export as an executable jar file from command line. I have external library jars also in the project. How can I get the executable jar file inclusive of all library jars from command line?

EDIT:: Now there is a challenge.There are actually two projects.One is PROJECT and other is Project_Framework. Both these folders are having pom.xml.The dependencies are written in pom.xml in PROJECT folder. PROJECT is dependen t on Project_Framework. After adding maven-shade plugin it is saying it cannot find the snapshot dependency of Project_Framework. How can I solve this?

@AlessandroDaRugna: There is a challenge for me in this question.There are actually two projects.One is `PROJECT` and other is `Project_Framework`. Both these folders are having pom.xml.The dependencies are written in pom.xml in PROJECT folder. Where should I add the plugin? This is indeed confusing for me. — Nevin Raj Victor, May 08 '15 at 09:15

You have to use the maven-shade-plugin to add all dependecies to your jar.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>1.7</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <finalName>${project.build.finalName}</finalName>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>META-INF/spring.handlers</resource>
                    </transformer>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>META-INF/spring.schemas</resource>
                    </transformer>
                </transformers>
            </configuration>
        </plugin>

Then Change directory to PROJECT_FRAMEWORK.Then type

mvn install

Then, again change directory to PROJECT. If you have added it, you can simply run

mvn package.

Don't use acient versions of [maven-shade-plugin. Current version is 2.3](https://maven.apache.org/plugins/maven-shade-plugin/) – khmarbaise May 08 '15 at 07:34
@khmarbaise: All my dependencies are written in `pom.xml`. So I believe there is no need of a plugin.I am expecting a command which should do it. – Nevin Raj Victor May 08 '15 at 07:49

@NevinRaj You need the plugin. maven do not include jar files to the artefact. This will do the plugin – Jens May 08 '15 at 07:51
@Jens So this plugin should be added in the `pom.xml`. Right? – Nevin Raj Victor May 08 '15 at 09:04
@NevinRaj Yes you have to add it. – Jens May 08 '15 at 09:08
@Jens: Now there is a challenge.There are actually two projects.One is `PROJECT` and other is `Project_Framework`. Both these folders are having `pom.xml`.The dependencies are written in `pom.xml` in `PROJECT` folder. Where should I add the plugin. – Nevin Raj Victor May 08 '15 at 09:11
@NevinRaj in `PROJECT` – Jens May 08 '15 at 09:26
@Jens Does the `maven-compiler` plugin also do the job of `maven-shade` plugin? – Nevin Raj Victor May 12 '15 at 11:32
@NevinRaj No. maven-compiler only compiles your sources. – Jens May 12 '15 at 11:39
@Jens : I have written only a `maven-compiler-plugin` but when i run the command `mvn package` it runs the entire program. – Nevin Raj Victor May 13 '15 at 05:46

@NevinRaj it compiles yor program. But it not includes third party jars. – Jens May 13 '15 at 05:48
