CodePudding user response：

Seems like there is an outdated Gradle version. I clone the Persona flutter project from GitHub.

Yes the project is working fine in version 2.2.9

implementation "com.withpersona.sdk2:inquiry:2.2.9"

But having an issue with version 2.2.34

implementation "com.withpersona.sdk2:inquiry:2.2.34"

I have seen the Persona android SDK v2 changelog https://docs.withpersona.com/docs/android-sdk-v2-changelog

where I found the recent releases, which are working on the latest Gradle version which you can see by cloning Persona Android SDK https://github.com/persona-id/persona-android-sdk

I follow the same and the issue resolved

Steps to resolve

1. Update kotlin version

   ext.kotlin_version = '1.7.10'

2. Update classpath

from

classpath 'com.android.tools.build:gradle:4.1.2'

to

classpath 'com.android.tools.build:gradle:7.2.2'

3. Remove compile options

    compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
    }
   

4. Update the gradle-wrapper.properties to the latest 7.3.3 version

    distributionBase=GRADLE_USER_HOME
    distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-bin.zip
    distributionPath=wrapper/dists
    zipStorePath=wrapper/dists
    zipStoreBase=GRADLE_USER_HOME
   

5. At last, you need to update the persona to the latest 2.2.37

   implementation "com.withpersona.sdk2:inquiry:2.2.37"

6. Now build the project.
