iText 7 Core is available via Maven on The Central repository. If you need all iText 7 modules, then you don't need to add the individual modules and you can just add this XML snippet in your pom.xml. Maven will then do all the heavy lifting for you and download the required modules from The Central Repository. Simply add iText 7 as a dependency to your pom.xml:
NOTE: We use "RELEASE" as the iText version in this installation, which will ensure you install the current release versions of the iText 7 modules. If your project requires a specific version of iText 7 to function correctly, ensure you replace this with your desired version number in your pom.xml.
