Guides the agent through upgrading a Capacitor plugin to a newer major version. Supports upgrades from Capacitor 4 through 8, including multi-version jumps. Covers automated upgrade via official migration tools, Android SDK targets, Gradle configuration, Java/Kotlin versions, iOS deployment targets, and manual step-by-step fallback for each version. Do not use for app project upgrade or non-Capacitor plugin frameworks.

Capacitor Plugin Upgrade

Upgrade a Capacitor plugin to a newer major version (4→5, 5→6, 6→7, or 7→8).

Prerequisites

Target Version	Node.js
5	16+
6	18+
7	20+
8	22+

The project must be a Capacitor plugin (not an app project).

Procedures

Step 1: Detect Current Version

Read

@capacitor/core

version from

package.json

(

devDependencies

or

peerDependencies

). Determine the current major version.

Ask the user for the target version. Default to the latest (8) if not specified.

Step 2: Execute Upgrade

For each major version jump between the current and target version, apply the corresponding upgrade guide sequentially:

Current → Target	Reference
4 → 5	`references/upgrade-v4-to-v5.md`
5 → 6	`references/upgrade-v5-to-v6.md`
6 → 7	`references/upgrade-v6-to-v7.md`
7 → 8	`references/upgrade-v7-to-v8.md`

For multi-version jumps (e.g., 5 → 8), apply each upgrade in order:

Read and apply
```
references/upgrade-v5-to-v6.md
```
Run
```
npm install && npx cap sync
```
, build, and verify the plugin's test/example app
Read and apply
```
references/upgrade-v6-to-v7.md
```
Run
```
npm install && npx cap sync
```
, build, and verify the plugin's test/example app
Read and apply
```
references/upgrade-v7-to-v8.md
```
Run
```
npm install && npx cap sync
```
, build, and verify the plugin's test/example app

Do not skip intermediate versions.

Step 3: Final Verification

After completing all upgrade steps:

bash

npm install
npx cap sync

Build the plugin's test/example app on both platforms to verify.

Error Handling

If automated upgrade tools fail, check the terminal output for which steps failed and apply those manually using the steps in the corresponding reference file.
If Android build fails after upgrade, run Tools > AGP Upgrade Assistant in Android Studio.
If iOS build fails, verify the deployment target matches the target version requirements in the reference file.
If Gradle property syntax warnings appear (v8+), search all
```
.gradle
```
files for property assignments without
```
=
```
and update them.
If a multi-version upgrade fails mid-way, fix the current version step before proceeding to the next.
