FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':google_api_headers:compileDebugKotlin'.

Answer 1

As a temporarily solution:-

Solution 1

Delete every line of code in GoogleApiHeadersPlugin.kt file and leave it blank, then add this flutter dependency

google_api_headers: ^1.3.0

Some of your packages needs updates so this is a temporary fix while you update your packages or awaiting updates.

Solution 2

you open this file producing error GoogleApiHeadersPlugin.kt (cmd + click on it in console for macOS) and cut all the try catch part

try {
            val info: PackageInfo
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.P) {
                info = context!!.packageManager.getPackageInfo(call.arguments<String>(), PackageManager.GET_SIGNING_CERTIFICATES)
                for (signature in info.signingInfo.apkContentsSigners) {
                    parseSignature(signature, result)
                }
            } else {
                @Suppress("DEPRECATION")
                info = context!!.packageManager.getPackageInfo(call.arguments<String>(), PackageManager.GET_SIGNATURES)
                @Suppress("DEPRECATION")
                for (signature in info.signatures) {
                    parseSignature(signature, result)
                }
            }

        } catch (e: Exception) {
            result.error("ERROR", e.toString(), null)
        }

so if method is empty and doing nothing

if (call.method == "getSigningCertSha1") {}else{}

then it works, I don't know why but it is a temporary solution, check if your libraries work ok

check this github issue

path to the file you should edit on windows os

C:\flutter\.pub-cache\hosted\pub.dartlang.org\google_api_headers-1.2.0+1\android\src\main\kotlin\io\github\zeshuaro\google_api_headers\GoogleApiHeadersPlugin.kt

Solution 3

you could downgrade your flutter version as you wait for the flutter libraries to be fixed
