Running imagej plugins in eclipse

[juliofederico]

Hi everyone! I have a problems to run imageJ plugins in eclipse. I Added all jar files needed in the referenced libraries and I have been looking for solutions in the web but nothing. I can compile and run the plugin using the fiji compiler but I get this exception (Exception in thread "main" java.lang.NullPointerException)  using eclipse. I think it could be a problem with the sentences: public void run(String arg) and public static void main(String[] args) whiches I have to change when I paste the code from fiji compiler to eclipse. What do you recommend me?
