Execution failed for task ':transformClassesWithMultidexlistForDebug' Ionic 3

Question

I let my Ionic 3 application and went back to it several months later, now when I try to build I get this error :

Execution failed for task ':transformClassesWithMultidexlistForDebug'.
> java.io.IOException: Can't read [MY_PATH\platforms\android\build\intermediates\transforms\jarMerging\debug\jars\1\1f\combined.jar] (Can't process class [module-info.class] (Unsupported class version number [53.0] (maximum 52.0, Java 1.8)))

I don't know how to fix it nor what cause this issue, could somebody help me please ?

In my build.gradle I already enabled multidex

defaultConfig {
        versionCode cdvVersionCode ?: new BigInteger("" + privateHelpers.extractIntFromManifest("versionCode"))
        applicationId privateHelpers.extractStringFromManifest("package")
        multiDexEnabled true 

        if (cdvMinSdkVersion != null) {
            minSdkVersion cdvMinSdkVersion
        }
    }

Not very good solution but was the only one I found, reinstall platform android

ionic cordova platform rm android

ionic cordova platform add android

After that I got the error "net::ERR_CLEARTEXT_NOT_PERMITTED" I found the solution here : Why am I seeing net::ERR_CLEARTEXT_NOT_PERMITTED errors after upgrading to Cordova Android 8?
