--------------------------------------------
{quote}You can add {{--stacktrace}} to gradle invocation, this should help in
diagnosing the root cause of those strange errors, Mike.
{quote}
Thanks, I'll add that option to the nightly benchmark's {{precommit}}
invocation, and I'll re-beast {{precommit}} with that. Let's see if the
strange errors happen again...
{quote}> I will now 1) go back to my original ~/.gradle/gradle.properties
I don't know if this is a good idea. This overrides global defaults... are the
settings generated on the first gradle run not working for you? Perhaps we
should improve those?
{quote}
Well, first off, the "auto-properties" solution requires two {{gradle}}
invocations, right? First runs w/o good defaults but writes
{{gradle.properties}}. Second run will use those properties. After a {{git
clean -xfd}} the {{gradle.properties}} is gone.
But second off, e.g. here is the {{gradle.properties}} written on my 128 core
{{beast3}} box:
{noformat}
[mike@beast3 trunk]$ cat gradle.properties
# These settings have been generated automatically on the first run.
# See gradlew :helpLocalSettings for more information.
systemProp.file.encoding=UTF-8
org.gradle.jvmargs=-Xmx3g
org.gradle.parallel=true
org.gradle.priority=normal
org.gradle.warning.mode=none
# You may disable the background daemon if it consumes too much memory.
org.gradle.daemon=true
org.gradle.daemon.idletimeout=900000
# Maximum number of parallel gradle workers.
org.gradle.workers.max=1
# Maximum number of test JVMs forked per test task.
tests.jvms=1{noformat}
Which I don't understand – why only 1 gradle worker and 1 test JVM?
I also would like to direct test temp output to my {{tmpfs}} mount instead of
local SSD. And I keep going back and forth about whether this {{daemon}} is a
good thing or not.
Finally, if push comes to shove, I blame [~rcmuir] for suggesting these
settings defaults :) I really have not much clue what these powerful sounding
gradle settings are doing!
