Incremental daemon builds crash sporadically with a NullPointerException

issue-acknowledged
gradle-3481

(Todor Boev) #1

Gradle Version: 2.13
Operating System: Windows 7

When the gradle daemon is enabled certain incremental builds crash when gradle attempts to scan the input files of a task for changes. It appears as though the DefaultPersistentDirectoryStore becomes closed mid-build. The issue is not always reproducible and I was not able to deduce any concrete bulid configuration that causes this. The issue disappears when the daemon is turned off via org.gradle.daemon=false

Here is an example stack trace of such a crash:

Hi Todor,

Thank you for making us aware. I have created GRADLE-3481. We are investigating this.

Hi Todor,

Wanted to follow up here after we released Gradle 3.0. We fixed a couple fundamental issues that may have caused this.

Could you please give Gradle 3.0 a try and report back if you still see this issue? Note that we have a bit more work here so this may be addressed by Gradle 3.1.

Cheers,
Eric
