build-toos/aapt2 issue with gradle in android termux

[amsitlab]

If we use gradle build tools in termux (android) to build android apps,
android-sdk build-tools/<version>/aapt2 is unused
cause android gradle plugin (AGP) will auto download and use aapt2 from https://maven.google.com/web/m_index.html#com.android.tools.build:aapt2
and that will produce an error in termux
because downloaded file contains executable for linux and not compatible for termux

current solution:

• use maven local repository in all build.gradle
• convert all jar file in ~/.gradle/cache/modules-2/files-1/ to maven local repository format by using this script (without finalizedBy)
• run gradle cacheToMavenLocal
• replace executable aapt2 in .m2/repository/com/android/tools/build/aapt2/< version >/aapt2-< version >.jar (downloaded by AGP from here ) with aapt2 provided by termux
• and rebuild gradle assembleDebug
