1 Chapter 1. Installation and Setup Gradle ( Ant) HSQLDB Hibernate Core Project Hierarchy 1 / 18

2 Getting an Gradle Distribution Why do I care? Ant vs Maven vs Gradle How do I do that? Download and unzip a binary release of Gradle to d:\javatool\gradle-2.6 folder gradle-2.6-all.zip Add the bin directory to your path add d:\javatool\gradle-2.6\bin to PATH 2 / 18

3 Check Your Java, and Gradle Version $ java version openjdk version "1.8.0_51" OpenJDK Runtime Environment (build 1.8.0_51-b16) OpenJDK 64-Bit Server VM (build b03, mixed mode) $ gradle version Gradle Build time: :15:06 UTC Build number: none Revision: 233bbf8e47c82f72cb898b3e0a96b85d0aad166e Groovy: Ant: Apache Ant(TM) version compiled on December JVM: 1.8.0_51 (Oracle Corporation b03) OS: Linux fc22.x86_64 amd64 3 / 18

4 Using the HSQLDB / H2 Database Engine How do I do that? When you build the examples in this book, the gradle will automatically download the HSQLDB and/or H2 JARs (and any other JARs you need) from the Maven repository at 4 / 18

5 Using Hibernate Core How do I do that? Our chosen release Hibernate Core GA Final Final Hibernate Tools GA When you build the examples in this book, the gradle will automatically download the Hibernate JARs (and any other JARs you need) from the Maven repository. 5 / 18

6 Setting Up a Project Hierarchy for Gradle How do I do that? $ mkdir <project-dir> $ cd <project-dir> $ mkdir -p src/{main,test/{java,resources $ mkdir -p src/{main,test/java/com/oreilly/hh/data (Linux/Unix only) com.oreilly.hh The example classes we're going to create are all going to live in here com.oreilly.hh. com.oreilly.hh.data We'll have our data beans in the com.oreilly.hh.data package 6 / 18

7 A quick test (Gradle build.gradle) apply plugin: 'java' sourcesets { main.resources.srcdir 'src/main/java' test.resources.srcdir 'src/test/java' repositories { jcenter() //mavencentral() dependencies { compile 'org.hibernate:hibernate-core:3.6.+' compile 'org.slf4j:slf4j-api:1.+' runtime 'ch.qos.logback:logback-core:1.+' runtime 'ch.qos.logback:logback-classic:1.+' runtime 'org.javassist:javassist:3.+' runtime 'org.hsqldb:hsqldb:2.+ runtime com.h2database:h2:1.+' testcompile 'junit:junit:4.+' testcompile 'org.hamcrest:hamcrest-library:1.+' task db( dependson: classes, type: JavaExec ) { main = 'org.hsqldb.util.databasemanagerswing' args '--driver', 'org.hsqldb.jdbcdriver', '--url', 'jdbc:hsqldb:file:build/music', '--user', 'sa' classpath = sourcesets.main.runtimeclasspath 7 / 18

8 A quick test (Dependency Search) 8 / 18

9 A quick test (Dependency Search) 9 / 18

10 A quick test (Dependency Search) 10 / 18

11 A quick test (Gradle build.gradle) $ gradle db :ch01:compilejava UP-TO-DATE :ch01:processresources UP-TO-DATE :ch01:classes UP-TO-DATE :ch01:db Download Download GA/javassist GA.jar... (repeating) 11 / 18

12 A quick test (hsqldb Database Files) $ ls data music.log music.properties music.script 12 / 18

13 Printing the dependency class path (Gradle build.gradle) build.gradle: task printclasspath << { println configurations.compile.aspath //println configurations.runtime.aspath task pprintclasspath << { configurations.compile.each { File file -> println file.name //configurations.runtime.files.each { File file -> println file.name $ gradle pprintclasspath $ gradle clean 13 / 18

14 Exercise #1: Learn Gradle (ex01/build.gradle) apply plugin: 'java' repositories { jcenter() //mavencentral() dependencies { compile 'org.slf4j:slf4j-api:1.+' runtime 'ch.qos.logback:logback-classic:1.+' testcompile 'junit:junit:4.11' testcompile 'org.hamcrest:hamcrest-library:1.+' test { testlogging { events "passed", "skipped", "failed", "standardout", "standarderror" outputs.uptodatewhen {false exceptionformat = 'full' aftersuite { desc, result -> if (!desc.parent) { println "\nresults: ${result.resulttype (${result.testcount tests, " + "${result.successfultestcount successes, " + "${result.failedtestcount failures, " + "${result.skippedtestcount skipped)" task helloworld(dependson: classes, type: JavaExec) { main = 'exercise.helloworld' classpath = sourcesets.main.runtimeclasspath task slf4j(dependson: classes, type: JavaExec) { main = 'exercise.slf4jlogback' classpath = sourcesets.main.runtimeclasspath 14 / 18

15 Exercise #1: Learn Gradle (compile and run App) $ cd ex1 $ gradle classes $ gradle helloworld :compilejava UP-TO-DATE :processresources UP-TO-DATE :classes UP-TO-DATE :helloworld Hello World! BUILD SUCCESSFUL $ gradle slf4j 15 / 18

16 Exercise #1: Learn Gradle (JUnit) $ gradle test :processtestresources UP-TO-DATE :testclasses :test... exercise.junittest setupclass() exercise.junittest > testsomethingelse teardown() exercise.junittest > testsomethingelse PASSED exercise.junittest > testonething teardown() exercise.junittest > testonething PASSED exercise.junittest > testanotherthing teardown() exercise.junittest > testanotherthing PASSED exercise.junittest teardownclass() BUILD SUCCESSFUL 16 / 18

17 Exercise #1: Learn Gradle (JUnit and Hamcrest) $ gradle test :processtestresources UP-TO-DATE :testclasses :test exercise.hamcresttest > testnumber PASSED exercise.hamcresttest > testcollection PASSED... BUILD SUCCESSFUL 17 / 18
