Build Failed due to leftShift() method not found in ":scalarinputapi:generateRelease"

I am getting issue while importing project in Android Studio.

Caused by: org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method leftShift() for arguments [android_release_aar_8aaffqenud6qsg8w8hrovmfvc$
_run_closure7@5f35a04c] on task ':scalarinputapi:generateRelease' of type org.gradle.api.DefaultTask.

        at org.gradle.groovy.scripts.internal.DefaultScriptRunnerFactory$ScriptRunnerImpl.run(DefaultScriptRunnerFactory.java:90)

I can see there is << available in "https://raw.githubusercontent.com/ArthurHub/release-android-library/master/android-release-aar.gradle" and this is deprecated android not allowed this.

I have research on this issue but not getting the solution.

Please help me..

Thank you

Hi, @rlogical-techsoft ! I resolved the issue by downloading Gradle file behind this link. File was added to the same level as the build.gradle that uses this file.

<< was replaced with doLast { ... }. The solution is not good because file behind this link may change but you won't receive any updates.

The other solution would be to lower Gradle version to 4.. In version 4. sign << was deprecated but still used. In 5.* it was removed.

Thanks for the bug report. I'll take a look.

@lizlooney : You mean you have downloaded the android-release-aar.gradle file and replaced << with doLast { ... }. Where you have placed in code or uploaded?

@rlogical-techsoft
Downloaded and physically placed the file on the same level as build.gradle that uses this file.

In build gradle next line

apply from: 'https://raw.githubusercontent.com/ArthurHub/release-android-library/master/android-release-aar.gradle'

was changed to

apply from: 'android-release-aar.gradle'

And inside this android-release-aar.gradle file the block using << was changed to

task generateRelease {
    doLast {
        println "Release ${version} can be found at ${localReleaseDest}/"
        println "Release ${version} zipped can be found ${buildDir}/release-${version}.zip"
    }
}
