I have a maven project with a lot of dependencies. I want to pack all in a jar with dependency using assembly plugin, but I don't won't all the dependencies jars unpacked in a big mess. I want all of them do go into lib folder, but I don't know how to add the class path. my pom:

He was probably reconfiguring his maven dependency plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.10</version>
<executions>
<execution>
<id>copy</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${distDirectory}/lib</outputDirectory>
<includeScope>runtime</includeScope>
</configuration>
</execution>
</executions>
</plugin>
Now, when your run mvn package
, all your dependency jars will go to target/lib
(or whatever your distDirectory is).

If maven-jar-plugin is not generating the entry Class-Path in the manifest file although you have set <addClasspath>true</addClasspath>
, make sure you are using version 2.2 or newer of the plugin.
It seems that the bug MJAR-83 in version 2.1 was preventing the plugin from listing the dependencies in Class-Path.
