Add-on debug

[Nick]

Hello,

I was wondering if it's possible to test an add-on by putting breackpoints, I would use the deploy in intelliJ, and eventually how to do it

Best regards

It is, yes.

We have these instructions for Eclipse: https://www.zaproxy.org/docs/developer/building-zap-with-eclipse/#debugging-add-ons

It should be similar for IntelliJ - if you work it out could you update these docs? :) https://www.zaproxy.org/docs/developer/building-zap-with-intellij-idea/

Cheers,

Simon

Ok thank I will try, but now I'm trying to load my code in the zap-extensions folder, so then I can put breackpoints, and it fails the JavaCompile for the -Werror flag, I know the plugin works if as a standalone project, do you know how I can fix it?

[psiinon]

No, I am not telepahic, or omnipresent :D

Maybe if you shared the error messages...?

[Nick]

Sorry,

I never encountered this kind of message so I assumed it had to be related to something specific of ZAP, my bad, I will list you the errors during the copyzapaddon task:

error: warnings found and -Werror specified

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':addOns:migt:compileJava'.
> Compilation failed; see the compiler output below.
  C:\Users\Utente\Desktop\ZAP IntelliJ\zap-extensions\addOns\migt\src\main\java\org\zaproxy\addon\migt\ParsingException.java:4: warning: [serial] serializable class ParsingException has no definition of serialVersionUID
  public class ParsingException extends Exception {
         ^
  1 error
  11 warnings

* Try:
> Run with --scan to get full insights.

It seems to found some warnings, and because of them it stop and returns an error. When compiling the project standalone I don't have any problems and the addon loads and work.

This are the warnings, I just noticed that they were missing: 

public class ParsingException extends Exception {
       ^

error: warnings found and -Werror specified

I was able to resolve the issue with the warnings and to deploy the addon on IntelliJ, I will update if I'm able to enter debug mode.
