I have a similar issue using Flutter

    Execution failed for task ':flutter_inappwebview:minifyReleaseWithR8'.
[        ] > java.util.zip.ZipException: zip END header not found

For some reasons this only happens when building a release but generating a debug apk works fine.

I tried everything about downloading gradle manually nothing works. Flutter suggests this fix:

[!] The shrinker may have failed to optimize the Java bytecode.            │ To disable the shrinker, pass the `--no-shrink` flag to this command.       To learn more, see: https://developer.android.com/studio/build/shrink-code 

However, when I compile with --no-shrink it seems that the directive is being ignored.

I have this in my build.gradle

buildTypes {
        release {
            shrinkResources false
            minifyEnabled false
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

Any suggestions will greatly help

I've faced same issue and in my case I had firstly open an android folder

android>gradel>wrapper>gradle-wrapper.properties

in gradle-wrapper.properties change

distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip

to

distributionUrl=https\://services.gradle.org/distributions/gradle-7.5.1-all.zip

And then invalid caches and restarted fixed my issue

Had a similar issue. What I did was I headed to my gradle-wrapper

android>gradle>wrapper>gradle-wrapper.properties

copied the link and pasted in my browser and directly downloaded the file.

distributionUrl=https\://services.gradle.org/distributions/gradle-7.6.3-all.zip

After download I pasted the zip file in the

C:\Users\USER\.gradle\wrapper\dists\gradle-7.6.3-all\aocdy2d2z8kodnny3rsumj8i8

If you ran the build command, then I believe there should be a folder created for that wrapper in the .gradle, so just locate the folder depending on your gradle version and paste the zip.

The issue occurs when I change the gradle wrapper in my app. This method is what I use to solve it
