Hi.
I am writing a little tutorial in my company about the use of the Maven
Assembly Plugin to build a executable jar, with all dependencies inside it.
When I was using Maven 2.2.1, the following would done the job:
...
<build>
<plugins>
...
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<archive>
<manifest>
<mainClass>com.company.classX</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
...
</plugins>
</build>
...
This time, however, I am using Maven 3.0.4, and I am getting this warning:
[WARNING] Cannot include project artifact: com.company.class; it doesn't
have an associated file or directory.
I read the plugin's documentation, but could not figure what is the problem.
Here is the complete pom I am using now:
<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

</plugins>
</build>
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.1.3</version>
</dependency>
</dependencies>
</project>
The resulting jar contains httpclient and all the dependencies it has, but
no code of mine is added in the jar, and I get this output in command line:

Does anyone please have any idea? I am getting crazy with this problem.
Thank you very much,
Kind regards,
