jebcli

Command-line APK decompilation helper backed by the adjacent JEB installation.

Requirements

• JEB home must point to a directory containing bin/app/jeb.jar.
• A JDK with javac on PATH for building. No large IDE is required.

JEB home resolution order:

1. --jeb-home or -JebHome
2. JEB_HOME environment variable
3. jeb.home in jebcli.properties
4. Current working directory

Persist JEB home in the repository-local config file:

powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 config set jeb.home D:\IT\Android\JEB-5.30.0.202506111623_by_CXV
powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 config get jeb.home
powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 config list

Build

From this repository:

powershell -ExecutionPolicy Bypass -File .\tools\build.ps1

Artifacts are written locally:

• build/classes/
• build/sources.txt
• dist/jebcli.jar

Use -Clean to remove and rebuild local build outputs:

powershell -ExecutionPolicy Bypass -File .\tools\build.ps1 -Clean

Run

powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 -Apk C:\path\app.apk -Out .\out\app

Equivalent positional form:

powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 C:\path\app.apk .\out\app

The output directory contains:

• decompiled/: JEB decompiler exporter output for Dalvik units.
• resources/: raw non-DEX APK entries copied from the package, preserving APK-relative paths. Binary XML and resources.arsc are not decoded.
• smali/: smali-style Dalvik disassembly text exported from JEB DEX units.
• jeb-projects/: local JEB project database files used by the headless engines context.
• metadata.json: input path, JEB home, status, timestamps, Java/resource/smali output counts, and errors.

Smoke Checks

Invalid input should fail before JEB analysis:

powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 -Apk missing.apk -Out .\out\missing

Explicit JEB home:

powershell -ExecutionPolicy Bypass -File .\tools\jebcli.ps1 -JebHome D:\IT\Android\JEB-5.30.0.202506111623_by_CXV -Apk C:\path\app.apk -Out .\out\app

Exit codes:

• 0: success
• 2: command-line usage error
• 10: validation error
• 20: JEB initialization error
• 30: analysis error
• 40: export error
