B4J Question Problem/bug? using B4JBuilder 7.31

[JackKirk]

I have just upgraded to Java 12 and B4j 7.31

I have a series of .bat files that do compilation of various B4J apps

I am getting the following error when the .bat files are run:

D:\XXXX\B4X\AWS EC2\FTPServer\YYYY>call "C:\Program Files (x86)\Anywhere Software\B4J\B4JBuilder" -BaseFolder="D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=Default
B4JBuilder v7.31
Java version: 12
BaseFolder: D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\Obfuscation
ProjectFile: FTPServer.b4j
System.IO.FileNotFoundException: Could not find file 'D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\FTPServer.b4j'.
File name: 'D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\FTPServer.b4j'

Could not find file 'D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\FTPServer.b4j'.

For some reason the folder \Obfuscation is recognised at the BaseFolder: echo but not when it goes to execute.

I have made absolutely no changes to the .bat file or B4J source - I have merely upgraded the Java and B4J environments.

I'm assuming this is some B4JBuilder bug but hesitate to say so - I've been wrong before!

Update: went back to B4J 7.0 (which I never used) - same problem.

Update: went back to B4J 6.51 (my prior working release).

B4JBuilder works but Java 12 is hiccupping:

Update: went back to Java 10.0.1 (my prior working release) - everything working.

 

[Erel]

Current version of B4J is compatible with Java 8, 9, 10 and 11. I recommend to use either 8 or 11. These are the long term supported versions.

Erel, I tried running B4J 7.31 with Java 10.0.1 and got:

D:\XXXX\B4X\AWS EC2\FTPServer\YYYY>call "C:\Program Files (x86)\Anywhere Software\B4J\B4JBuilder" -BaseFolder="D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=Default

Note is reporting:

BaseFolder: D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\Obfuscation

but then

Could not find file 'D:\XXXX\B4X\AWS EC2\FTPServer\YYYY\FTPServer.b4j'.

B4JBuilder is somehow losing the last folder (\Obfuscation).

With Java 10.0.1 this also happens with B4J 7.0 but not B4J 6.51.

 

[Erel]

Does it only happen with obfuscation enabled?

Does it only happen with obfuscation enabled?

Java 10.0.1 B4J 7.31 -obfuscate=False
Same result

I am getting same problem with Java 10.0.1 + B4A 9.00 - see new thread:

NOTE B4A

I just tried Java 11.0.2 - doesn't work - see new thread:

It is difficult to help you like this. You are keep adding irrelevant information in multiple threads. I'm sorry but if you want my assistance then you should start a single thread and only provide the information I ask you.
