I'm trying to compile a Java project with Maven and Eclipse but I tried a lot of solutions seen on the web but none of them seem to work. I just want to build the application, create a runnable jar and include the needed libraries. I tried maven-dependency or maven-assembly but I surely miss something because I fail every time.
Here is my pom.xml, is it ok or does it miss something?

Use the maven-assembly-plugin to generate an executable jar with dependencies

It's not working for you because ,you have added the plugin execution in the pluginManagement section. pluginManagement is supposed to be used for managing the plugin version and configuration.
Minimal version of how your build tag should look like :
<build>
<!-- if you have a multimodule project, I will probably manage this in the
parent pom -->
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>${assembly.version}</version>
</plugin>
</plugins>
</pluginManagement>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<groupId>org.apache.maven.plugins</groupId>
<executions>
<execution>
<id>make-executable-jar-with-dependencies</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.coderplus.sample.MainClass</mainClass>
</manifest>
