Android Question [SOLVED] Problem/bug? using B4ABuilder 9.00

[JackKirk]

I have just installed B4A 9.00 on Java 10.0.1 and am getting:

D:\XXXX\B4X\Customer - Android\YYYY>call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -BaseFolder="D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=customer
B4ABuilder v9.00

ProjectFile: Customer.b4a

when trying to use B4ABuilder.

Very similar to B4J problem:

Does same thing on B4A 8.80 but works on B4A 8.50

 

[Erel]

Follow the installation instructions: https://www.b4x.com/b4a.html

 

[JackKirk]

Follow the installation instructions: https://www.b4x.com/b4a.html

OK:

• I uninstalled Android, Java and B4A
• I installed Java JDK v8 (actually jdk1.8.0_202) as per https://www.b4x.com/b4a.html - Installation - Step 1
• I installed Android exactly as per https://www.b4x.com/b4a.html - Installation - Step 2
• I installed B4A v9.00 and followed other instructions as per https://www.b4x.com/b4a.html - Installation - Step 3

I then ran my .bat file that does compiles and get:

D:\XXXX\B4X\Customer - Android\YYYY>call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -BaseFolder="D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=customer
B4ABuilder v9.00
BaseFolder: D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation
ProjectFile: Customer.b4a
System.IO.FileNotFoundException: Could not find file 'D:\XXXX\B4X\Customer - Android\YYYY\Customer.b4a'.
File name: 'D:\XXXX\B4X\Customer - Android\YYYY\Customer.b4a'

Could not find file 'D:\XXXX\B4X\Customer - Android\YYYY\Customer.b4a'.

Short of it: problem is still there, B4ABuilder is echoing:

BaseFolder: D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation

but then saying:

Could not find file 'D:\XXXX\B4X\Customer - Android\YYYY\Customer.b4a'

somewhere between these 2 events B4ABuilder is losing the Obfuscation folder.

 

[Erel]

I'm able to compile with obfuscation turned on. What happens if you run it from the project folder without the BaseFolder parameter?

 

[thetahsk]

Perhaps a path or a white space problem.
What happens if you remove all white spaces from path and filenames ?

 

[JackKirk]

What happens if you run it from the project folder without the BaseFolder parameter?

I do not understand exactly what you mean by this, my current command is:

D:\XXXX\B4X\Customer - Android\YYYY>call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -BaseFolder="D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=customer

how are you suggesting I modify it?

I suspect you may be missing the point - it appears to me that it has nothing to do with obfuscation - B4ABuilder internally is dropping the last nested folder.

What if you try a similar command with multiple nested folders in the BaseFolder parameter and see if you get a similar result?

Perhaps a path or a white space problem.
What happens if you remove all white spaces from path and filenames ?

I have been running the .bat file of which the above forms a part for several years and through multiple releases of B4A.

This problem was introduced at B4A v8.80 (which I never used) and perpetuated in v9.00 - v8.50 works fine.

There is an almost identical problem with B4J v7.00 and v7.31 - v6.51 works fine.

D:\XXXX\B4X\Customer - Android\YYYY>call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -BaseFolder="D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=customer

I mean the blanks in your path "D:\XXXX\B4X\Customer - Android\YYYY" .

 

[JackKirk]

thetahsk,

I was responding to Erel's comment:

not yours.

 

[Erel]

D:\XXXX\B4X\Customer - Android\YYYY>call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -BaseFolder="D:\XXXX\B4X\Customer - Android\YYYY\Obfuscation" -task=Build -obfuscate=True -configuration=customer

Try this:

cd Obfuscation
call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -task=Build -obfuscate=True -configuration=customer

 

[JackKirk]

Try this:

cd Obfuscation
call "C:\Program Files (x86)\Anywhere Software\Basic4android\B4ABuilder" -task=Build -obfuscate=True -configuration=customer

OK that workaround works.

You now obviously realise the dimensions of the bug - when will it be fixed (particularly in B4J)?

Thanks...

 

[Erel]

when will it be fixed

I cannot say. However there is a very simple workaround which I recommend you to use for now.

 

[JackKirk]

I cannot say. However there is a very simple workaround which I recommend you to use for now.

The workaround is simple, however the implementation is a bit of a problem when your project involves 17 B4J apps each one having a compiler .bat file that use B4JBuilder twice - all of which have a master on my desktop and a copy on an AWS EC2 instance and/or a headless legless PC in the bush.

Far easier to wait until it is fixed.
