How to include the dependencies in the built jar?
Hi all,
assumed we have a project with packaging jar. When we build the project with "mvn package", a jar is build. But the dependencies in the project are not included in the built jar. Is it possible to include the dependencies in the built jar?
Regards
Thomas

If you say "there is no such convention for a .jar file", what does ahd for what use is "jar-with-dependencies"?
**********************************
What do you mean?
As far as I know, while the .war and .ear formats allow jars to be
nested inside jars, there is no such convention for a .jar file.
If you use a maven package type of "war" or "ear" in the pom, then
a .war or .ear does get created, and the dependencies are present.

Simon

Yup, Wendy's right. Here's a sample we've used:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorId>jar-with-dependencies</descriptorId>
<finalName>the-jar-name</finalName>
<outputDirectory>target/</outputDirectory>
<workDirectory>target/assembly/work</workDirectory>
<!-- include runtime deps -->
<scope>runtime</scope>
<archive>
<manifest>
<!-- a main class for using the jar from a shell -->
<mainClass>gr.abiss.someproject.App</mainClass>
<addClasspath>true</addClasspath>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- this is used for inheritance merges -->
<phase>package</phase>
<!-- append to the packaging phase. -->
<goals>
<goal>attached</goal>
</goals>
</execution>
</executions>
</plugin>

Hi Simon,
thanks for the answer.
And sorry, I will put my question by the mailinglist by logger.

This is really the wrong mailing list. See:
http://logging.apache.org
However the answer is that the file needs to be in the *classpath*. The
WEB-INF directory of a webapp is not in the classpath.
The directory WEB-INF/classes is in the classpath.

Do you mean you want to dynamically create a configuration file at
runtime? Don't do that, it is a bad idea.
In most cases, there is no reason to set the logging configuration from
your program; just use a normal configuration file. That allows someone
to modify the configuration after installing the webapp.
However if you really must configure log4j from your code, then use the
log4j api to do this instead of writing a configuration file.
Please send all further questions to the log4j email list, NOT to this
list.
Regards,
Simon

Hi all,
1.
Where should I save the "log4j.properties"? I think it should be under /webapp//WEB-INF?
2.
How can the program find this file (I mean how to write in the java)?

Thomas

Take a look at the assembly plugin. There are a few standard
assemblies... it sounds like jar-with-dependencies might be what you
want.
If not, you can define your own descriptor to create what you need.
