Error message

[repackageWith7z]7z repackage signed apk fail,you must install 7z command line version first, linux: p7zip, window: 7za, path=%s

What it means

Thrown by ResourceRepackage.repackageWith7z after running the 7-Zip compression pipeline: the expected 7z-repackaged signed APK (mSignedWith7ZipApk) was not produced. This means the 7-Zip command failed — most commonly because the p7zip/7za command-line tool is not installed or not on PATH — so the compression ran but generated no output APK.

Solutions

1. Install the 7-Zip command line tool: p7zip on Linux (apt-get install p7zip-full) or 7za on Windows, and ensure it is on PATH
2. Verify the configured 7z executable path in the build config is correct and executable
3. If 7z compression is not required, disable the 7zip repackage option so the pipeline uses the regular zip output
