Android Question Library creation

[WebQuest]

Hi community I'm trying to create a library with eclipse I followed Erel's tutorial on creating a b4a library with eclipse but when generating the jar file with 'generate javac' I get a compilation error does anyone know how to solve? I state that I do not use SLC because the browser is blocking the download.

Use SLC to build the project: https://www.b4x.com/android/forum/t...uild-libraries-without-eclipse.29918/#content

Hi Erel thanks for the reply. I am using SLC I indicated the library path but I get this error:
[CODE = b4x] Fase iniziale: compilazione del codice Java.
javac 14.0.1

Completato con successo.
Fase iniziale: creazione del file jar.
Accesso al percorso 'C: \ Program Files (x86) \ Anywhere Software \ Basic4android \ Libraries \ FristLib.jar' negato.

Did you start in administrator mode so that you also have access to folders that are not in documents?

 

[Erel]

The additional libraries folder is misconfigured. It shouldn't be the same as the internal folder.

 

[WebQuest]

I ran as administrator and configured the additional libraries folder now I get this error:

Starting step: Compiling Java code.
javac 14.0.1

Completed successfully.

Error.

 

[Erel]

Looks like the doclet tool is missing from OpenJDK. You will need to install Oracle Java 8 and configure B4A to use it.

 

[WebQuest]

I currently have jdk14 the latest version of java. I have set the b4a paths to jdk8. But keep getting the same error about compiling the xml file.

 

[Erel]

Please post the logs when it compiles with Java 8.

Error.

 

[WebQuest]

I will try to create the library from the b4a compiler.

@Erel

I am encountering this same error trying to build a Library for B4J. Are you suggesting that we use Java 8 for a jar that we want to reference in B4J? I am a little concerned about that because I do not think it will make it through the Apple notarization process. The reason I "know" this is because I have an old program that uses Java 8 and I could not notarize it through Apple because of that.

For reference, this is my attempt at using SLC.

Thank you.

 

[Erel]

Use Java 8. It has no effect on the notarization (it also has no effect on the built jar).

Will do. Thank you!
