Re: Setting dependency with plugin generated jar

Thu, 11 Nov 2010 22:53:20 -0800

If you simply have classes for action / view I suppose they should not be referenced outside the war. If you have model classes its good to package them as separate jar. Trying to generate the jar in the same war project will only complicate things for you. You should create a separate module for model classes, which then should create a jar and then it can be referenced by your other components including your war file. 

Thanks,

by mentioning "Looking for classes", I did not meant the source code, I was
mentioning . I extracted the war file manually using 7zip tool and found
that it had compiled .class files. I know that war contains all resources.
Our project don't have separate modules for Model, View and Controllers. And
its high time to setup everything like that. so, I am finding a way to
generate jar also in the war project and setting fer other projects depend
on that.

War project has almost no code or preferably no code .
Code is in jar project.

War project has WebContent stuff (configurations, XML, images, JSPs) and
depends on your Jar project for its classes. It will create a WAR file
with the classes from the dependencies.

I tried using classifier already, it is not working.

Currently, the maven project where I have all the implementations is
generating war file. If I add another maven project for generating JAR,

from

where will this project get the source files from? I can add a dependency

on

first project then my second project will have access to the war

generated,

right. What I wrote in my earlier mail was, should my second project

extract

the war. locate the .class files then again package them in to jar? but

that

will be lots of work right?

How do I add the "projectVersion.jar" as a dependency?

Use dependency classifier. Specifying type as jar is not required since
it is the default.

<dependency>
<groupId>your.groupId</groupId>
<artifactId>your-artifactId</artifactId>
<version>${project.version}</version>
<classifier>modals</classifier>
<type>jar</type>
</dependency>



Separate modules you mean separate Maven Projects? Then I don't get the
other modules source files right. I will have to unpack the war and

repack

them as jar?

Yes separate module means separate Maven Project. I did not understand
the rest of your comment.

     To make it work the Maven way, you should ideally separate the jar
from the war file as an independent module. Your war file will then
depend on the jar.

Not sure if your packaging is war, adding maven-jar-plugin creates a

jar

file? If it does then you can use build-helper-maven-plugin to install
the additional jar generated to the repository.

In any case you can even depend on the war file with dependency
definition like,

<dependency>
<groupId>mycorp.groupid</groupId>
<artifactId>mycorp-artifactid</artifactId>
<version>myversion</version>
<type>war</type>
</dependency>

But I would strongly recommend separating jar and war as separate

module.

I have a scenario where in my pom generates a war file. Whereas I

also

need a

jar of the same to be referenced by other projects. So I added a
maven-jar-plug-in to generate a jar for the same. As the pom was

installing

this generated jar as the war to the repository. I mentioned a

classifier

to

differentiate this jar with war. Now the problem is how I should put

a

dependency in other projects on this jar file.

Thanks in advance
