Gradle build failed:Execution failed for task ':common:scala:compileScala'.

[axiqia]

I'm trying to setup openwhisk on ubuntu. Getting build failed error when building. Any idea?

Environment details:

$ docker --version                   
Docker version 18.09.0, build 4d60db4

$ uname -a
Linux ubuntu 4.4.0-138-generic #164-Ubuntu SMP Tue Oct 2 17:16:02 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Steps to reproduce the issue:

./gradlew distDocker

Provide the actual results and outputs:

Execution failed for task ':common:scala:compileScala'.

Can you run ./gradlew distDocker --debug --stacktrace > gradle.log and share the log file? That may provide clue on why its failing

Also if its an existing checkout which you recently update then try running ./gradlew clean first as I was also seeing some strange error post update to Gradle 4.10.2 and clean helped

@chetanmeh I'm sorry to bother you.
I have found the reason that virtual memory of my vps is running short the kernel OOM (Out of Memory) killer forcibly kill individual builds, you can check the original answer here.

I increased swap space and then build success.

cd /opt
mkdir swap
cd swap
dd if=/dev/zero of=swapfile bs=1M count=10240
mkswap swapfile
swapon swapfile

Thank @axiqia for details. Would close this issue then as its more of a setup issue
