Follow those steps for installing full version:

1. Download xText

Help -> Install new Software -> Add -> Download from: http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/

2. Download and import

• Download The project
• Copy the project into the work-space
• Import The xText project in eclipse: File -> Import -> General -> Existing Project into workspace.

3. Run

• right click the grammar file (org.xtext.BPMN_translator -> src -> org.xtext -> BPMN_translator.xtext) -> run as -> Generate xText artifact
• Wait for generation to finish
• Right Click the folder: org.xtext.BPMN_translator -> Run as Eclipse Application.

4. Get Started

• Create a new blank java project
• Create a new File with the extension ".translator"
• A window will pop up asking if you want to convert the project in an xtext project -> yes

5. Usage

• In the file ".translator" you can write any kind of BPMN xml.
• Everytime a change will occur a new file with the translation in code will be generated.

6. Optional

For better understand how the parse tree will be generated is suggested to use ANTLRWorks: https://www.antlr3.org/works/ . Copy all the grammar in the file /org.xtext.BPMN_translator/src-gen/org/xtext/parser/antlr/internal/DebugInternalBPMN_translator.g into ANTLRWorks and run it: a graphical parse tree will be generated.
