Getting All Maven Dependencies

If you are running any static analysis tool for Java, you know how hard it is to get all dependencies from a client. This is especially true if the application uses Maven build. Most clients use Nexus, which makes it even harder to get libraries to compile.

During one such engagement, one of my team members was struggling to compile the code. And anytime you have compilation errors, many of the static analysis tools produce 0 findings.

That's when I sent this simple command line option to my team member, who in turn was able to ask the client to send them all the dependencies using this command. And this worked like a charm, we had all libraries required to compile the code, the tool was happy, we were happy and the client was happy as well.

So, here it is. Make sure you can compile the code without any errors.

From a command line within your project, run "mvn clean compile"

Next, once you have a clean compilation, run the command "mvn dependency:copy-dependencies". This will copy all the dependencies into the target\dependency folder.

Take a look at the target\dependency folder, you have all the libraries to compile and can now configure any tool to scan your code successfully.

  1. I am having a project with multiple sub-project. Is there a command which can copy the dependencies of all projects without duplicates to one folder? I have tried using maven build options for multiple modules but did not get expected result.
