上一篇gradle學習文章學到構建java項目，這一篇來看看怎么講上一次的java項目變成eclipse項目 ## 1.標示eclipse項目 ~~~ apply plugin: 'eclipse' ~~~ build.gradle如下 ~~~ apply plugin: 'java' apply plugin:'eclipse' repositories{ mavenCentral() } dependencies { compile group:'commons-collections',name:'commons-collections',version:'3.2' testCompile group:'junit',name:'junit',version:'4.0+' } sourceCompatibility = 1.5 version = '2.0' jar { manifest { attributes 'Implementation-Title':'Gradle Quickstart', 'Implementation-Version':version } } test { systemProperties 'property':'value' } uploadArchives { repositories { flatDir { dirs 'repos' } } } ~~~ 執行gradle eclipse構建項目 ~~~ <pre name="code" class="html">qianhuis-Mac-mini:1228_1 qianhui$ gradle eclipse :eclipseClasspath Download https://repo1.maven.org/maven2/commons-collections/commons-collections/3.2/commons-collections-3.2.pom Download https://repo1.maven.org/maven2/junit/junit/4.0/junit-4.0.pom Download https://repo1.maven.org/maven2/commons-collections/commons-collections/3.2/commons-collections-3.2.jar Download https://repo1.maven.org/maven2/junit/junit/4.0/junit-4.0.jar Download https://repo1.maven.org/maven2/commons-collections/commons-collections/3.2/commons-collections-3.2-sources.jar Download https://repo1.maven.org/maven2/junit/junit/4.0/junit-4.0-sources.jar :eclipseJdt :eclipseProject :eclipse BUILD SUCCESSFUL Total time: 2 mins 33.783 secs ~~~ 但是目錄結構沒發現什么改變，希望隨著學習的深入能發現什么端倪。 ## 2.多重項目構建 項目目錄結構如下： multprojec目錄下含有3個項目［api,services,shared］,services項目下又含有［shared，webservice］  ## 3.settings.gradle 為了構建多重項目，需要在多重項目的根目錄定義一個文件,包含所有的子項目。該文件名必須定義為settings.gradle ~~~ qianhuis-Mac-mini:multproject qianhui$ touch settings.gradle qianhuis-Mac-mini:multproject qianhui$ ~~~ 在該文件中用include來包含所有的子項目 ~~~ include "shared","api","services:webservice","services:shared" ~~~  ## 4.配置注入 使用configuration injection來管理所有的項目，主項目像一個容器，通過subprojects方法能夠遍歷所有的子項目,然后為每一個項目注入特殊的配置信息。這樣我們就能夠很容易的為依賴和壓縮包定義配置內容。如下所示，我們首先根據settings.gradle里的配置信息得到所有的子項目，然后逐個位每個項目注入下面的配置。 ~~~ subprojects{ apply plugin:'java' apply plugin:'eclipse-wtp' repositories{ mavenCentral() } dependencies{ testCompile 'junit:junit:4.11' } jar{ manifest.attributes provider:'gradle' } } ~~~ 這個時候在根項目下執行gradle build，你會發現它為每個項目都做了構建 ~~~ qianhuis-Mac-mini:multproject qianhui$ gradle build :api:compileJava UP-TO-DATE :api:processResources UP-TO-DATE :api:classes UP-TO-DATE :api:jar :api:assemble :api:compileTestJava UP-TO-DATE :api:processTestResources UP-TO-DATE :api:testClasses UP-TO-DATE :api:test UP-TO-DATE :api:check UP-TO-DATE :api:build :services:compileJava UP-TO-DATE :services:processResources UP-TO-DATE :services:classes UP-TO-DATE :services:jar :services:assemble :services:compileTestJava UP-TO-DATE :services:processTestResources UP-TO-DATE :services:testClasses UP-TO-DATE :services:test UP-TO-DATE :services:check UP-TO-DATE :services:build :shared:compileJava UP-TO-DATE :shared:processResources UP-TO-DATE :shared:classes UP-TO-DATE :shared:jar :shared:assemble :shared:compileTestJava UP-TO-DATE :shared:processTestResources UP-TO-DATE :shared:testClasses UP-TO-DATE :shared:test UP-TO-DATE :shared:check UP-TO-DATE :shared:build :services:shared:compileJava UP-TO-DATE :services:shared:processResources UP-TO-DATE :services:shared:classes UP-TO-DATE :services:shared:jar :services:shared:assemble :services:shared:compileTestJava UP-TO-DATE :services:shared:processTestResources UP-TO-DATE :services:shared:testClasses UP-TO-DATE :services:shared:test UP-TO-DATE :services:shared:check UP-TO-DATE :services:shared:build :services:webservice:compileJava UP-TO-DATE :services:webservice:processResources UP-TO-DATE :services:webservice:classes UP-TO-DATE :services:webservice:jar :services:webservice:assemble :services:webservice:compileTestJava UP-TO-DATE :services:webservice:processTestResources UP-TO-DATE :services:webservice:testClasses UP-TO-DATE :services:webservice:test UP-TO-DATE :services:webservice:check UP-TO-DATE :services:webservice:build BUILD SUCCESSFUL Total time: 6.571 secs ~~~ 相應的子項目目錄下都生成了jar包。但是要注意上面的配置不會對root project產生作用。 ## 5.項目之間的依賴 比如A項目依賴B項目，那么在A項目下定義一個build.gradle 。寫法如下: ~~~ dependencies{ compile project(':B') } ~~~ 那么在A項目構建前，會先構建B項目。然后將B項目的jar包作為A項目的依賴jar，構建A的jar包。 ## 6.調配項目 ~~~ task dist(type: Zip) { dependsOn spiJar from 'src/dist' into('libs') { from spiJar.archivePath from configurations.runtime } } artifacts { archives dist } ~~~ 具體的信息學習完再講。暫時我也不清楚
