java cmdline application in eclipse with existing opensource libraries

Description A java cmdline application (no GUI) that creates, based on input (PDF/A file and several string arguments) an output (PDF/A-3 which contains embedded XML). For the sake of this description, we call the application "pre-convert". The job consists of creating a working "pre-convert" application and delivery of the full eclipse IDE (currently neon.2) project with proper inline documentation so that our programmer can enhance, correct, develop further on the base you deliver. The application "pre-convert" is most likely a very simple application, especially due to the fact that the code is almost complete in the [login to view URL] example (see below). But we need the complete programming environment and documentation on how to use it. Ideally, proper test classes are added to the project as well (see JUnit Tests). The project should allow to later add additional classes for output variants instead of ZUGFeRD. Examples are another type of XML or a specific text format that is unique to a European financial booking application. However, the coding of those additional classes and output formats is not part of this job. This might be an add-on later. Existing open source libraries are available for creation of the special XML file and the merging into the PDF/A-3 file. This output format is called ZUGFeRD (Basic profile) and is a standard to for electronic invoicing. In short, it represents an invoice in PDF/A3 format which in turn contains an embedded XML file. The PDF/A-3 file shows the visual representation of the invoice, while the embedded XML file contains the data elements of the invoice in a structured way. Existing open source libraries: • Mustangproject library on GitHub: [login to view URL] ○ There is an example on GitHub which implements almost all major code that is needed. See [login to view URL] ○ The following mustangproject document describes which additional libraries (i.e. PDFBox, PrefLight, XMPBox) need to be imported/added and how: [login to view URL] ○ The main website of the project is [login to view URL] Context of "pre-convert" The application "pre-convert" will be called from our tool "PRE" which provides the PDF/A file and some extracted data from this file as arguments. The output (a ZUGFeRD file) will be imported into compatible accounting systems. Input: - PDF/A document (file) - about 14 string arguments - Optional: the arguments in a defined format in a text file, one line per argument - Examples of arguments: PaymentReference=RE-20151008/504 (see getNumber()) ID=08.10.2015 (see getIssueDate()) Name=Theodor Est (see getName()) Street=Bahnstr. 42 (see getStreet()) PostcodeCode= 88802 (see getZIP()) Etc. - Possible example of call (not complete number of arguments):pre-convert -Z -if=[login to view URL] -of=[login to view URL] PaymentReference="RE-20151008/504" ID=08.10.2015 Name="Theodor Est" Street="Bahnstr. 42" PostcodeCode=88802 …… Actions of application: - Collect input (PDF/A and arguments) - Create XML file with content collected as arguments with the help of library - Merge XML and PDF with the help of library Output: - PDF/A-3 file which embeds the ZUGFeRD XML file
