Proguard issue while building an extension using the latest sources

Taifun · September 27, 2022, 3:35pm

I cloned the latest sources and while trying to build an extension using ant extensions -Dproguard=1
I get the following error

No such file or directory: C:\DATEN\Git\appinventor-sources\appinventor\build\components\deps\google-api-client-beta.jar

Building without Proguard works fine...
Which files need to be updated? I guess others also will run into that issue...

Hmm. I wonder if there's a better way of structuring the proguard task so we don't have to enumerate all of the JARs like that. The idea behind the deps folder is that it contains all of the JAR files, so a glob ought to do the trick but I'm not sure that it would work with the libraryjar element.

Actually, we did implement it this way in the extension template repo, so we should probably just apply that adjustment to the main repo.
