Gradle - nimrody/knowledgebase GitHub Wiki

• Gradle for devops

• Running with a proxy

  $ ./gradlew -Dhttps.proxyHost=XXXXX -Dhttp.proxyHost=XXXXX -Dhttp.proxyPort=XXXXX
  -Dhttps.proxyPort=XXXXX -Dhttp.proxyUser=XXXXX -Dhttp.proxyPassword=XXXXX
  -Dhttps.proxyUser=XXXXX -Dhttps.proxyPassword=XXXXX
  build

• Running a single test or group of tests

  sh ./gradlew :policy:test --tests "ReportsServletTestConcur*"

• Run with the application plugin in debug mode: gradle run --debug-jvm

• Setup default JVM args applicationDefaultJvmArgs = ["-Dgreeting.language=en"]

• Setup run arguments with run.args "aa", "bb", ...

• gradle --daemon to run in daemon mode (faster)

• gradle --help for other command line options

• Gradle - create new java project gradle init --type java-library

• Use settings.gradle to make gradle search other directories for modules. E.g.,

  include '../rep/server/Tenserver/policy' findProject(':../rep/server/Tenserver/policy')?.name = 'policy'

• More than one application with the application plugin

  task groupEventsByUsers(type: CreateStartScripts) { mainClassName = 'periodic.GroupEventsByUsers' applicationName = 'group' outputDir = new File(project.buildDir, 'scripts') classpath = jar.outputs.files + project.configurations.runtime }

  applicationDistribution.into('bin') { from(groupEventsByUsers) fileMode = 0755 }

• Application plugin - set jvm defaults and command line arguments

  apply plugin: 'application'

  mainClassName='analysis.MainClass' applicationDefaultJvmArgs=['-Xmx2G']

  run.args "../../databaseSchema/server.local.config"

  // add the public directory (js/html/css) to the distribution applicationDistribution.from('public') { into 'public' }

• Run a java program (without the application plugin)

  task run(type: JavaExec) { main = "analysis.MainVideoAnalysis" classpath = project.sourceSets.main.runtimeClasspath //args "../../databaseSchema/server.local.config", "com.rge.sport5", "full_20151228" args "../../databaseSchema/server.local.config", "com.rge.sport5", "full_20160114" jvmArgs "-Xms5G", "-Xmx5G" }

• Add a local jar file as a dependency: compile files('xxx.jar')

• Execute external command: (the following sets the version code according to the git version count):

  def cmd = 'git rev-list HEAD --first-parent --count' def gitVersion = cmd.execute().text.trim().toInteger()

  android { defaultConfig { versionCode gitVersion } }

Shadow plugin for fat jars

• Shadow plugin documentation

  // Use "gradle shadow" to generate a fat-jar

  buildscript { repositories { mavenCentral() } }

  plugins { id 'com.github.johnrengelman.shadow' version '1.2.4' }

  group 'tensea' version '1.0-SNAPSHOT'

  apply plugin: 'java' apply plugin: 'application'

  sourceCompatibility = 1.8 mainClassName = 'Obfuscate'

  shadowJar { baseName = 'obfuscate' classifier = null version = null }

Speedup

• Enable parallel builds

  echo 'org.gradle.parallel=true' >> ~/.gradle/gradle.properties

• Enable the gradle daemon

  echo 'org.gradle.daemon=true' >> ~/.gradle/gradle.properties

• Enable configuration on demand

  echo 'org.gradle.configureondemand=true' >> ~/.gradle/gradle.properties
