NullPointerException in ProfileEventAdapter.completed(ProfileEventAdapter.java:72)

Thag · October 25, 2014, 3:32am

After upgrading to gradle 2.0 we started seeing this NPE. We didn’t see this in the initial QA. It wasn’t until we started running a lot of concurrent jobs that this started happening.

Not sure what other info to provide. It’s not a stack trace that I’ve seen anywhere else in this forum or in jira.

Here’s the env:

#> gradle -version

Seeing this in gradle 2.1 as well. Trace line numbers slightly different but it’s the same problem. This is current bug.

Can a JIRA issue be created to track this issue? We are seeing this frequently during the development of Grails 3.0 (master branch)

Peter_Niederwieser · November 21, 2014, 1:26am

Raised GRADLE-3200.

Radim_Kubacki · December 2, 2014, 8:52am

Thag/Graeme,

can you give exact steps to reproduce your problem? I have a theory that something wrong happens very early during the build initialization and the build fails and tries to run regular finish sequence but the ProfileEventAdapter wasn’t even initialized and throws this NPE. Knowing what exactly happens will help us to apply a fix with confidence rather than doing just some poor workaround.

Possibly there can also be some additional information in Gradle log.

Graeme_Rocher1 · December 2, 2014, 9:17am

I haven’t seen the issue for a while with the latest build snapshots of Gradle, so maybe it has been resolved already. It was reproducible simply by using the Gradle tooling API to run a command in 2.2 final

Radim_Kubacki · December 2, 2014, 9:28am

OK, we can wait for a while and close the bug if there is no update from you before 2.3 release.

Thag · December 2, 2014, 11:26pm

Is there a specific milestone build we should try to see if this is still reproducible?

luke_daley · December 2, 2014, 11:27pm

You can use the nightly build.

I see the same NullPointerException in 2.2. I only see this when running in a docker container. I also tried distributionUrl=https://services.gradle.org/distributions-snapshots/gradle-2.4-20141229230057+0000-bin.zip and get the same error

Seeing this after changing the system locale to Japanese:
