Failed to execute goal org.codehaus.mojo:rpm-maven-plugin:2.0.1:rpm (default-cli) on project inv-project

Question

I am getting the error below while creating an RPM of my Maven Project.

I am able to package the Jar successfully but RPM creation is failing.

Note: I am trying on Windows 7

Let me know what is missing here?

Answer 1

You need to have the rpm command. Different operating systems may have different ways to to install it. Cygwin is a way to have it in windows. I had the same problem in Ubuntu and solved it by:

sudo apt install rpm

So depending on the OS/Distribution you may have different ways to install RPM

Answer 2

The rpm-maven-plugin just calls the operating system rpm commands, so you need to run it on RedHat or CentOS where those commands are available. This plugin will not do anything on other operating systems.
