Hi!

I’m using Gradle 3.5 and for I frequently get the DaemonDisappearedException.

Hi @Marcin_Grzejszczak,

Any tips for reproducing this issue? I’ve run ./gradlew generateDocumentation dozens of times and haven’t seen an issue. Could you share the output of ./gradlew --version?

Also, would you try running with Gradle 3.4.1 to see if the problem only happens to you with that version?

Thanks!

That’s the problem - there’s nothing else I can suggest you do :wink:

I’ve ran ./gradlew --version

I’ll try to play around with 3.4.1 and I’ll get back to you

@Marcin_Grzejszczak,

If you have access to another machine (or even a VM or container on the same machine), I’d also like to know if you see the same behavior. I don’t know how readily reproducible the problem is for you.

5

I had the same problem on the same machine on another project so it’s not really project related I guess :confused:

6

Was that project using the same version of Gradle?

Hi! Sorry for the delay. Recently I stopped seeing this issue so maybe that was sth wrong with my laptop. Let’s close this issue.

Hi, I have linux server on AWS EC2 instance, which runs gradle generates APK and sends it to related client…
Recently after updating to gradle 3.5… i am having this issue I have tried many things

Including having daemon as false in gradle.properties
org.gradle.jvmargs=-Xmx1536M
org.gradle.daemon=false

tried to run ./gradlew --no-daemon build

tried to increase =-Xmx1536M to =-Xmx2048m

but nothing helps… I keep getting same error, the stacktrace says

* What went wrong:
Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)

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

* Exception is:
org.gradle.launcher.daemon.client.DaemonDisappearedException: Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)
