B4J Question SLC BADoclet.writeClass java.lang.NullPointerException

[MicroDrie]

When I try to create a jar file with SLC, this part goes to creating the xml documentation file. I have the latest software version of both the SLC program and the C:\Program Files\Java\jdk1.8.0_361\bin\javac.exe version. How do I get rid of the error message?

B4J is configured to use Java 8, right?

Does your project include Java classes except of your wrappers? If so then hide them with the @Hide annotation. Not all features of Java classes are supported by the doclet tool.

Yes

Yes, indeed ?there are three public interfaces which have all three a public static class

If so then hide them with the @Hide annotation

I search the forum and the Internet for documentation how to use the @Hide option. I try to write @Hide just before the class:

   @Hide("Checker")
   public static class Checker implements TypeQualifierValidator<RegEx> {

This gives me the following error:

Starting step: Compiling Java code.
javac 1.8.0_361
D:\Data\1 B4X SLC\SimpleLibraryCompiler\SimpleLibraryCompiler\javax\src\javax\annotation\Nonnegative.java:18: error: cannot find symbol
@Hide("Checker")
 ^
  symbol:   class Hide
  location: @interface Nonnegative
1 error


Error.

So what is the correct place and format for the Doclet @hide option?

Make sure you have this import in your code
import anywheresoftware.b4a.BA.Hide;
Then just use it as below

 import anywheresoftware.b4a.BA.Hide;
 //...
 @Hide
public static class Checker implements TypeQualifierValidator<RegEx> {
