Java.io.File cannot be added to org.gradle.api.artifacts.Configuration

I got a problem in Android-Studio after updating one project to a new gradle-plugin (14.0.2):

Error:Cause: java.io.File cannot be cast to org.gradle.api.artifacts.Configuration
Possible causes for this unexpected error include:<ul><li>Gradle dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process may be corrupt.
<a href="stopGradleDaemons">Stop Gradle daemons and sync project</a></li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

I have tried all the suggested things but have no success. Also this project builds nicely on the console - stuck here. Any hint can help.

This type of error can be corrected by changing

plusConfigurations += project.configurations.compile


To:

plusConfigurations += [ project.configurations.compile ]

There was the same problem. I have an appengine module in a project. Updating the gradle config for it to 1.9.17 resolved this for me

As per Ales above, upgrading to 1.9.17 resolved this for me. I was on 1.9.7 earlier.

Specifically, in any appengine projects you have included, update the versions in your build.gradle file for both buildscript dependencies and general dependencies. I have updated for:

buildscript dependencies:

classpath 'com.google.appengine:gradle-appengine-plugin:1.9.17'

dependencies:

appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.17'
compile 'com.google.appengine:appengine-api-1.0-sdk:1.9.17'

compile 'com.google.appengine:appengine-endpoints:1.9.17'
compile 'com.google.appengine:appengine-endpoints-deps:1.9.17'

I solve it with the following steps

  • quitting android studio.

  • delete folders with names

    • appName /build

    • APPNAME /app/build

    • APPNAME /.gradle

  • start android studio then go to build

    >rebuild project

hope this work with you
