Gradle build painfully slow


Whenever I try and run a gradle build in Idea - particularly for Android - it is agonisingly slow.

I have added "org.gradle.daemon=true" to the project's, but it does not appear that a daemon is started at any time.  If I go into settings and specify that the local gradle distribution should be used instead of the wrapper then the daemon is started , but I get the following error: 

Error:Cause: org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection
Possible causes for this unexpected error include:<ul><li>Gradle's 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 (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</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 following all the advice given in the error, but it makes no difference.
