Fastlane Migration

Use this skill when you need to migrate from Fastlane supply to the gplay CLI.

Preconditions

• Existing Fastlane metadata directory structure.
• gplay CLI installed and authenticated.
• Familiarity with the source Fastlane directory layout.

Migrate Command

Basic migration

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata

Dry run (preview without writing files)

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --dry-run

Migrate specific locales only

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --locales en-US,es-ES,fr-FR

Dry run with specific locales

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --locales en-US,ja-JP \
  --dry-run

What Gets Migrated

The command converts the Fastlane directory structure into the gplay metadata format:

Fastlane source structure

fastlane/metadata/android/
├── en-US/
│   ├── title.txt
│   ├── short_description.txt
│   ├── full_description.txt
│   ├── video.txt
│   ├── changelogs/
│   │   ├── 100.txt
│   │   └── 101.txt
│   └── images/
│       ├── phoneScreenshots/
│       │   ├── 1.png
│       │   └── 2.png
│       ├── icon.png
│       └── featureGraphic.png
├── es-ES/
│   └── ...

Migrated output structure

metadata/
├── en-US/
│   ├── listing.json
│   ├── changelogs/
│   │   ├── 100.txt
│   │   └── 101.txt
│   └── images/
│       ├── phoneScreenshots/
│       │   ├── 1.png
│       │   └── 2.png
│       ├── icon.png
│       └── featureGraphic.png
├── es-ES/
│   └── ...

File conversions

• title.txt, short_description.txt, full_description.txt, video.txt are consolidated into listing.json.
• changelogs/ are copied as-is.
• images/ are copied as-is.

Workflow Examples

Full migration from Fastlane

# 1. Preview the migration
gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --dry-run

# 2. Run the actual migration
gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata

# 3. Verify the output
ls -R ./metadata

# 4. Import to Play Store
gplay sync import-listings \
  --package com.example.app \
  --dir ./metadata

Incremental locale migration

# Migrate English first
gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --locales en-US

# Verify and test
gplay sync diff-listings \
  --package com.example.app \
  --dir ./metadata

# Migrate remaining locales
gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --locales es-ES,fr-FR,de-DE,ja-JP

CI/CD migration validation

# In CI, validate that migration produces expected output
gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata-test \
  --dry-run

# Check exit code
if [ $? -eq 0 ]; then
  echo "Migration validation passed"
else
  echo "Migration validation failed"
  exit 1
fi

Replacing Fastlane Supply Commands

Best Practices

1. Always dry-run first - Preview the migration output before writing files.
2. Migrate locale by locale - Start with your primary locale and verify.
3. Keep Fastlane source - Do not delete the Fastlane directory until fully migrated and verified.
4. Validate after migration - Use gplay validate listing to check character limits.
5. Update CI/CD gradually - Replace Fastlane commands one at a time.
6. Version control the output - Commit migrated metadata to track changes.
