No, by default, the Eclipse application doesn't have native export to PDF file format. It's hard to develop a plugin to enable this function, while there are simple ways to do it. The most simple way is to install a virtual PDF printer. Download and install CutePDF Writer. Install the application and then reload Eclipse and load the code. Once the code has been set-up, go to File > Print and choose the CutePDF Writer. After a few seconds you will be prompted to save the PDF file and that's it.
