B4J Question MergeLibraries break my lib

#MergeLibraries: False = I can run app in Release mode
#MergeLibraries: True = App crash in Release mode

The error is completely unrelated... I cannot get it.

This behavior also create unusable app with standalone package.

Library:

Selenium Library - Pnd_Selenium

Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. Library...

I need to build standalone package, any solution?

Possible reasons for such issues:
1. The jar is signed and merging the jars breaks the signature.
2. There are multiple files with the same name. This one is not too difficult to solve once you find it. Check the files inside the jars, under META-INF.

 

[Pendrush]

After some research, I found that some files from my library were not copied into the JAR file that was compiled in release mode with flag #MergeLibraries: True.
If I copy ALL the files from my kotlin-selenium-all.jar library, WITHOUT overwriting, into the compiled JAR everything works fine.

You can also see the difference in the size of the files, it is obvious that something is also missing in the Release JAR:

My Library:

Pnd_Selenium.xml              70,210
Pnd_Selenium.jar               6,457
kotlin-selenium-all.jar   30,139,004

Release JAR (#MergeLibraries: True):

Selenium7.jar             26,156,717

Any solution?

Which files weren't copied?

 

[Pendrush]

2940 Files are missing in Release Jar.
PDF with folders and file names is attached to this post.

 

[Erel]

With the exception of services and native, META-INF subfolders are not copied. Simply copying many of the folders there will not work for various reasons.
You can make a test and manually copy the folders to the merged jar.

 

[Pendrush]

Simple copy missing files from META-INF subfolder make app to work as it should.

EDIT:
Only one file make app to work on path: META-INF\selenium-build.properties

Is there any chance to make app in release mode and somehow to instruct B4J to include this file?

Example of adding a file to a merged jar during "build standalone package":

#CustomBuildAction: before packager, %JAVABIN%\jar.exe, uf BCTextInCLV.jar -C C:\Users\H\Downloads Files\1.txt

The file is located in C:\Users\H\Downloads\Files\1.txt and it will be included in the jar under Files\1.txt.
BCTextInCLV.jar is the name of this app.

My test worked. I was able to read the file. I'm not 100% sure that it will work with the META-INF file, after it is packed.

 

[Pendrush]

\META-INF\selenium-build.properties - folder and file inside project Files folder

Solution for: build standalone package

#CustomBuildAction: before packager, %JAVABIN%\jar.exe, uf Selenium16.jar -C e:\B4J\_WRAP\Selenium\Selenium16\Files META-INF\selenium-build.properties

Solution for: compile app in release mode with #MergeLibraries: True

#CustomBuildAction: 2, %JAVABIN%\jar.exe, uf Selenium15.jar -C e:\B4J\_WRAP\Selenium\Selenium15\Files META-INF\selenium-build.properties
