Android Question Is there a Way to Batch Clean Projects

[Mahares]

I have several folders with B4A projects. Is there a way or B4J code to batch clean all of them one after the other to reduce the folders sizes other than individually opening a project and cleaning it before opening another. Usually, when I archive projects, I like to clean them first.
Thank you

If you compile a project using the commandlinebuilder it will be cleaned while building the Project.

B4ABuilder v11.20
Global Java version: 11
Usage example: B4ABuilder -task=Build -obfuscate=False
Parameters:
-Task Possible values: Build, BuildBundle or BuildLibrary. Build - Release compilation (default value), BuildBundle - AAB bundle. BuildLibrary - Library compilation.
-BaseFolder The project folder. Default value is the current folder.
-Project Main project file. Can be omitted if there is only one b4a file in the base folder.
-NoSign If True then the APK / AAB is not signed.
-Obfuscate If True then the compiled APK / AAB will be obfuscated.
-ShowWarnings Whether to list the compilation warnings.
-Configuration Build configuration.
-Optimize Whether to include an optimization step during the byte conversion (dexer).
-NoClean Whether to skip the project cleaning step.
-Output Compiled APK name (does not affect libraries builds).

These projects have been compiled in debug over time. For instance, I have a folder that is called: C:\MiscPrograms2021. There are say 50 projects there now. How do you isssue a batch file command to process all the projects inside that folder and clean them, preferably in the back ground although not essential that it is done in the background. I just want to reduce the sizes and simply clean them.

write a small b4j app which finds all the projects and call the batchcompiling-step using shell.

I have not used these batch programs or shell in B4A , so I have no idea what you are talking about
Thank you

Time to learn something new i guess ;-)

Try to use the forumsearch. I´m pretty sure you´ll find some examples of using shell.

The functionality that you are looking for is implemented in the "zipper" tool, the tool that is used for the export as zip feature in B4XPages projects.

The source code is available here: https://www.b4x.com/android/forum/threads/comment-links-with-date-and-time.132262/post-834930
It is quite short but it is not so simple. It collects all files other than the files that you want to delete. You can use it as a base for a program that cleans the projects.
