Remove only comments with macros?

[Lilianne-Blaze]

Could you please add an option to Maven plugin that allows removing comments but only those that contain JCP macros? So that javadocs and code-explaining comments remain untouched?

[raydac]

if file preprocessed then such comments will be removed automatically and how to be if file not preprocessed but for instance such code snippet cleared of jcp comments?

//#if DEBUG
  // Hello debug
  System.out.println("Hello debug");
//#else
  // No debug
  System.out.println("No debug");
//#endif

we will get clean result

  // Hello debug
  System.out.println("Hello debug");

  // No debug
  System.out.println("No debug");

how to be in the case?

Basically given that code:

    public static long getMyPid() {
        System.out.println("(getMyPid called)");
        long retVal = 0;
        // #if preprocess.java.version >= 9
        // use new API
        retVal = ProcessHandle.current().pid();
        // #else
        // use old MXBean hack
        // $retVal = getMyPidOld();
        // #endif
        return retVal;
    }

Normally I get this:

    public static long getMyPid() {
        System.out.println("(getMyPid called)");
        long retVal = 0;
        // JCP! if preprocess.java.version >= 9
        // JCP> // use new API
        // JCP> retVal = ProcessHandle.current().pid();
        // JCP! else
        // use old MXBean hack
        retVal = getMyPidOld();
        // JCP! endif
        return retVal;
    }

With keepComments=false I get this:

    public static long getMyPid() {
        System.out.println("(getMyPid called)");
        long retVal = 0;

        retVal = getMyPidOld();

        return retVal;
    }

I would like to get this:

    public static long getMyPid() {
        System.out.println("(getMyPid called)");
        long retVal = 0;

        // use old MXBean hack
        retVal = getMyPidOld();

        return retVal;
    }

Something like keepNormalComments or keepNonmacroComments would be nice

ok, I will check

I've made some improvements and now keepComments allows such variants:

• true it works as previously and keeps all comments
• false it removes all java formatted comments
• keep_all it works as true
• remove_c_style it works as false
• remove_jcp_only removes only JCP directives
  if you use gradle then just use keepComments='remove_jcp_only'
