NullPointerException from TaskPathProjectEvaluator

We are still occasionally (as of 19-Dec-2016) receiving the exception below when attempting to run any gradle task (i.e. originally failed attempting ‘gradle test --tests…’, but also fails with ‘gradle tasks’). This is a multiple-project build.

It seems that this begins to happen after some time running tasks within the project (i.e., tasks worked previously, then start failing as below).

I do have other stacktraces where it failed similarly at TaskPathProjectEvaluator.java:35 (instead of :42 as below), which is the same source code, project.evaluate();

Gradle Version: 2.14.1
Operating System and JVM version: OpenSUSE, JVM 7.1
Is this a regression? unknown


* What went wrong: 
while trying to invoke the method org.gradle.api.internal.project.ProjectInternal.evaluate() of a null object loaded from local variable 'project' 

* Try: 
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Are you by any chance using configure-on-demand?
