NullPointerException when running task from command line in grandchild project directories


(Grant Hutchins) #1

When we run a task on a two-level deep “grandchild” subproject from the top-level project directory, it works great. But when we run the same task from that subproject’s directory, it fails.

We don’t have the same problem for direct child subprojects.

Unfortunately, we don’t get a useful error message. The entire stacktrace shows org.gradle classes all the way down so we don’t know what in our configuration is triggering the problem, or if it’s a Gradle bug.

Here is the failing run as a scan: https://scans.gradle.com/s/3zf5zwcywxvpu
For this run, we ran ../../gradlew test from our ./backend/api/ directory.

And here’s a scan of running the same build successfully: https://scans.gradle.com/s/g6mzjhxnd34rs
For this run, we ran ./gradlew :spatial-backend:api:test from the top directory.

It also fails when we try running the fully-qualified ../../gradlew :spatial-backend:api:test, with this scan: https://scans.gradle.com/s/yeuf7gnihze6m

Any ideas?

Output:

* What went wrong:
java.lang.NullPointerException (no error message)

Stacktrace:

* Exception is:
java.lang.NullPointerException
