51. Hello Gradle build.gradle task hello << { println 'Hello world!' } > gradle -q hello Hello Gradle!

52. gradle task != ant task gradle task == ant target

53. Groovy в Gradle build.gradle task count << { 4.times { print &quot;$it &quot; } } > gradle -q count 0 1 2 3

54. Dependencies build.gradle task hello << { println 'Hello world!' } task count(dependsOn: hello) << { 4.times { print &quot;$it &quot; } } > gradle -q count Hello world! 0 1 2 3

55. Lazy dependencies build.gradle task hello(dependsOn: 'lazy') << { println 'Hello world!' } task lazy << { println 'so lazy...' } > gradle -q hello so lazy... Hello world!

56. Java Plugin build.gradle apply plugin: 'java' > gradle build ...

57. Java build-cycle customization build.gradle apply plugin: 'java' test.doFirst { println 'Before testing...' } test.doLast { println '...after testing.' }

58. Repos build.gradle apply plugin: 'java' repositories { mavenCentral() } dependencies { compile group: 'commons-collections', name: 'commons-collections', version: '3.2' testCompile group: 'junit', name: 'junit', version: '4.+' }

59. Ant build.gradle ant.importBuild 'build.xml' task ant << { ant.echo(message: 'hello from Ant') ant.zip(destfile: 'archive.zip') { fileset(dir: 'src') { include(name: '**.xml') exclude(name: '**.java') } } }
