How to compile javacc files everytime before running project in eclipse

Question

I have an eclipse project which uses javacc files (jjt and jj) and i would like to know how i can configure the run option on my project, so that it automatically does the following (in order):

• Compile jjt file using javacc (jjtree command)
• Compile jj file using javacc which was created in the compilation above (javacc command)
• Compile java files (created from the jj file) using javac command
• Run project?

I have a working .bat file which executes correctly from the command line, but i needed to run in it eclipse for faster development and easier code correction.

Any help would be greatly appreciated!

Answer 1

If you use the JavaCC eclipse plugin, then it should run jjt, javacc, and compile each time you save your .jjt file. Get it at http://eclipse-javacc.sourceforge.net/

Answer 2

You can configure what exactly happens on "Run" in Eclipse, afaik there is also an option to execute external applications before actually running.
