Running Jar file created by Maven
Hi guys,
I'm new to Maven. I have this problem that I created a Maven project in
netbeans, added dependencies, and build it successfully, it runs in Netbeans
as well. but if I try to build it from the command prompt using mvn install,
it build the whole staff, but when I try to run the jar file, it just fails
becuase it cannot find the library files (dependencies), looks like maven
doesn't add those files, although it downloads them...
please help me, i'm looking for the answer for quite a while now.
thanks
Tom

Seems shade plugin can have it's conflict resolution customized -
here<http://jira.codehaus.org/browse/MSHADE-43?focusedCommentId=164742&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_164742>is
solution for appending spring metadata. +1 for shade plugin features,
-1
for its documentation.

Stevo.

Re: Running Jar file created by Maven
Posted by Stevo Slavić <ss...@gmail.com>.
Just tried shade plugin,
this<http://www.thekua.com/atwork/2008/10/generating-a-single-fat-jar-artifact-from-maven/>assembly
plugin usage example, jar - maven-dependency-plugin combination,
and fatjar - they all seem to do same thing, and it's not enough in some
cases. Some libraries depend on their manifest metadata, like spring, and
last man wins conflict resolution doesn't work in that case. I'm not legal
expert but I think unpacking and repackaging libraries has legal
consequences too.
One-jar v0.96 used by most recent onejar-maven-plugin has some class loader
bugs which prevents spring framework component scan feature to work. That
bug is present for quite some time, one-jar library doesn't seem to be
actively maintained.
IMO, Java, language of the Web, is not best option for CLI.

Stevo.

Re: Running Jar file created by Maven

Which one is better?
maven-jar-plugin/maven-dependency-plugin
maven-shade-plugin
onejar-maven-plugin
fatjar
Why is that choice better than the other solutions?
Is the one which is "well maintained" always the better choice?
How do you define the "well maintained"-ness?
Just because it is debugged more frequently does it mean it is better?
It is possible that the other one did not have that much problems and
this is why it was not changed frequently.

Always nice to have choices.
Now, which one is better, the onejar-maven-plugin or fatjar?

Maven does not pack jar into jar. You can use assembly plugin to do that (as Eric Lewis wrote), but you can also use dependency plugin to copy dependencies (needed libraries) to you Target directory (or directory where your main jar is located).

If you do so, the jar files need to be included in the resulting jar file, or you have to add it to the classpath, via -cp ...

What kind of project are you talking about? Is it a pure Java project or
does it run inside glassfish (for example)? What class files are missing?
How does the stacktrace look like?
Try to add the missing artifacts to the pom.

No, it does not. It actually knows, which libraries are included and where they are (this includes also transitive dependencies.) but when you run java -jar only the generated jar is on the classpath, not the maven repository. So you have to tell maven, to include these artifacts inside the generated jar.
Fortunately there are a lot of plugins who can help you with this (so you don't have to include them manually.) I haven't used Maven for that purpose very often, but i have seen this plugin [1], which should help you. Maybe there is even an easier way, but i think this one is pretty straightforward. The plugin Mark suggested would do the job as well i think. So it is up to you which one to use.

If it's really a standalone app, you can also use the maven-shade-plugin [1] for creating an 'uber-jar' which contains all the dependencies.

Betreff: Running Jar file created by Maven
Hi guys,
I'm new to Maven. I have this problem that I created a Maven project in
netbeans, added dependencies, and build it successfully, it runs in Netbeans
as well. but if I try to build it from the command prompt using mvn install,
it build the whole staff, but when I try to run the jar file, it just fails
becuase it cannot find the library files (dependencies), looks like maven
doesn't add those files, although it downloads them...
please help me, i'm looking for the answer for quite a while now.
thanks
Tom
