Include maven dependencies inside jar file

Hi all.

I´m newbie in maven.

I have a Maven project and I need to build a jar file with the maven
dependencies inside, like I do with export jar as runnable in Eclipse to
execute the functionality from the command line.

What plugin can I use for this with what config?

Thanks.

Hi,
As you already saw, there's a special classloader to handle embedding jars
into jars (which is in fact not standard).

There is (was?) a maven plugin called onejar-maven-plugin that would do
exactly that. This is a variant (currently offline so I can't double-check)
of the fatjar-maven-plugin.

Cheers

Oh, I forgot to mention: I set up my pom so the classpath of my main
jar includes lib/, so all my users have to do is unzip it and run the
main jar.

As Anders Hammar said, there is some classpath magic to the way
Eclipse creates executable jars containing other jars.  I wanted
something like that, but instead I ended up creating an assembly that
creates a zip file.  The zip file contains my main executable jar,
along with all the dependencies in a lib/ directory.  Because I wanted
the zip file to contain an artifact from a project that depends on my
main jar, I had to separate the assembly pom from my main pom.  Now I
build my main project, build the artifact that depends on it, and then
build the assembly.

In that case, I cannot explain the error you seem to have run into.

IIRC, there is no Java standard to put dependency JARs in a jar file. So I
believe there is some Eclipse magic (hence that file) to get that rolling.

Wayne, I do the check and yes the dependency is inside the exec jar and yes inside that dependency I found the class AxisFault.class.

When I ask about a class loader and put the eclipse example it´s because I see this difference when compare the two jar, one generate by eclipse and the another by maven.

Unzip your jar file (or just drill into it) and see if that AxisFault.class file is inside the jar you created.

I really have no idea how Eclipse creates executable jars, nor any special interest in it. I'm here to talk about Maven.

Unzip your jar file (or just drill into it) and see if that
AxisFault.class file is inside the jar you created.

RE: Include maven dependencies inside jar file

I have two jar, one created with eclipse and another with maven. Both have the same dependencies but the one with maven have this error:

> Exception in thread "main" java.lang.NoClassDefFoundError:
> org/apache/axis2/AxisFault

I double check and maven include this dependency inside the exec jar: axis2-1.6.1.wso2v6.jar and this dependency have org\apache\axis2\AxisFault.class

I could be a problem with the class loader? Eclipse include this package inside the exec jar: org\eclipse\jdt\internal\jarinjarloader

It seems you are missing a necessary dependency, thus the NoClassDefFoundError you ran into. Looks like you need to add a dependency to Axis2.

If you want the deps extracted, you need to do a combination of [1] and [2].

If you want the dep jars included in the final jar, I think you best option
is to use the maven-assembly-plugin [3]. You also need to make the final jar
executable in this case.
