Wasabi fails on build - Maven plugin - maven

Question

See the solution below
Using Ubuntu 16.04 on Google Cloud
Everything is done as noted here https://github.com/intuit/wasabi.
After successfully bootstraping the wasabai
by running:
$ ./bin/wasabi.sh bootstrap
and getting
Everything looks all right!
...
installed dependencies.
Then I reboot the machine
$ sudo reboot
and try running the build
$ ./bin/wasabi.sh build
which obviously fails, this is the output I see:

Solution
I don't know if it makes any sense but what fixed the issue was moving my cloud machine from micro to much more powerful one n1-standard-4 (4 vCPUs, 15 GB memory)

Answer 1

can you try the following:
% WASABI_MAVEN="-e -X" ./bin/wasabi.sh build
additionally one could try issuing the reported failed mvn invocation directly, ie:
% mvn -e -X -Pdevelopment clean -Dmaven.test.skip=true package javadoc:aggregate
clearly none of the codebase is compiling given the first module fails.
i don't see why a reboot would matter unless logged in as a different user, some directory is owned by 'root' and not writable/deletable, etc.
let's fix this :)
