| # Local developer settings # | ||
| ############################# | ||
| # | ||
| # The first invocation of any task in Solr gradlew will generate and save this project-local 'gradle.properties' file. | ||
| # This file contains the defaults you may (but don't have to) tweak for your particular hardware (or taste). Note there | ||
| # are certain settings in that file that may be _required_ at runtime for certain plugins (an example is the spotless/ | ||
| # google java format plugin, which requires adding custom exports to JVM modules). gradlew only generates this file | ||
| # if it's not already present (it never overwrites the defaults) -- occasionally you may have to manually delete (or move) | ||
| # this file and regenerate from scratch. | ||
| # | ||
| # This is an overview of some of these settings. | ||
| # | ||
| ############### | ||
| # Parallelism # | ||
| ############### | ||
| # | ||
| # Gradle build can run tasks in parallel but by default it consumes all CPU cores which | ||
| # is too optimistic a default for Solr tests. You can disable the parallelism | ||
| # entirely or assign it a 'low' priority with these properties: | ||
| # | ||
| # org.gradle.parallel=[true, false] | ||
| # org.gradle.priority=[normal, low] | ||
| # | ||
| # The default level of parallelism is computed based on the number of cores on | ||
| # your machine (on the first run of gradle build). By default these are fairly conservative | ||
| # settings (half the number of cores for workers, for example): | ||
| # | ||
| # org.gradle.workers.max=[X] | ||
| # tests.jvms=[N <= X] | ||
| # | ||
| # The number of test JVMs can be lower than the number of workers: this just means | ||
| # that two projects can run tests in parallel to saturate all the workers. The I/O and memory | ||
| # bandwidth limits will kick in quickly so even if you have a very beefy machine bumping | ||
| # it too high may not help. | ||
| # | ||
| # You can always override these settings locally using command line as well: | ||
| # gradlew -Ptests.jvms=N --max-workers=X | ||
| # | ||
| ############# | ||
| # Test JVMS # | ||
| ############# | ||
| # | ||
| # Test JVMs have their own set of arguments which can be customized. These are configured | ||
| # separately from the gradle workers, for example: | ||
| # | ||
| # tests.jvms=3 | ||
| # tests.heapsize=512m | ||
| # tests.minheapsize=512m | ||
| # tests.jvmargs=-XX:+UseParallelGC -XX:TieredStopAtLevel=1 -XX:ActiveProcessorCount=1 | ||
| # | ||
| ################# | ||
| # Gradle Daemon # | ||
| ################# | ||
| # | ||
| # The gradle daemon is a background process that keeps an evaluated copy of the project | ||
| # structure, some caches, etc. It speeds up repeated builds quite a bit but if you don't | ||
| # like the idea of having a (sizeable) background process running in the background, | ||
| # disable it. | ||
| # | ||
| # org.gradle.daemon=[true, false] | ||
| # org.gradle.jvmargs=... | ||
