Capacitor Filesystem error in Android and Xcode: HttpURLConnectionBuilder has private access in HttpRequestHandler

Capacitor

I try to download a file in my ionic+vue app, but when I add the Capacitor filesystem plugin:

npm install @capacitor/filesystem
npx cap sync

My package.json:

    "@capacitor/android": "4.3.0",
    "@capacitor/app": "4.0.1",
    "@capacitor/core": "4.3.0",
    "@capacitor/filesystem": "^5.2.1",

The error when I build in Android:

node_modules/@capacitor/filesystem/android/src/main/java/com/capacitorjs/plugins/filesystem/Filesystem.java:324: error: HttpURLConnectionBuilder has private access in HttpRequestHandler
        HttpRequestHandler.HttpURLConnectionBuilder connectionBuilder = new HttpRequestHandler.HttpURLConnectionBuilder()

The error in Xcode:

Cannot find 'HttpRequestHandler' in scope

I’m lost with this problema, and don’t know what happens with that Filesystem capacitor plugin… Any help will be welcome!

You can’t use Capacitor 5 plugins with Capacitor 4.
