I have 2 Projects namely Project_1 and Project_2.
Both projects are Maven and I am using Netbeans.
I want to include the jar of Project_1 in Project_2 which I am doing like this.
The problem is when I include the jar I do not get any compile time error, however I get a NoClassDefFoundError exception at runtime.
When I include the Project_1 in Project_2 by performing the steps mentioned here. (The Open Project example). I do not get any errors. Neither runtime nor compile time.
Can you please explain me what am I missing here?
Update
Project_2 is deployed on a Server which is not in my local machine however Project_1 is in my local machine.
Inclusion of Project_1 into Project_2 as a project was done for testing in my local machine.
First of all, a good rule of thumb to adopt is never use the system scope and system path to pull in dependencies. In my experience there’s always a better way 🙂
If Project_2 depends on Project_1, then first install it’s jar into the local repository:
Watch the output you’ll discover the jar is placed somewhere under the following directory:
Once this is done the jar will be available as a normal dependency to the second build
The local repository ensures the projects are now decoupled from each other. Assuming you’re using snapshot revisions of Project_1, the Project_2 build will always retrieve the latest revision built and tested.
Update
You should use a Maven repository manager to share jars between machines/teams. Recommendations are contained in the following answer:
Share jar of the module with another team
How to configure Maven to use a repository like Nexus is described in it’s documentation.
As described in the deploy plugin documentation you’ll need to add a distributionManagement section to your POM (detailing the repository URL) and then upload the project’s jar to your repository as follows:
