gradle - 如何构建一个带有 lib 目录和其他 jar 的 jar？

Question

在 gradle 中 - 如何将 jar 嵌入到 lib 中的构建输出 jar 中 目录（特别是 lib/enttoolkit.jar 和 lib/mail.jar）？

Answer 1

如果您的项目中的一个目录（让我们称之为libs）内有所有的jar，您只需要这个：

jar {
    into('lib') {
        from 'libs'
    }
}

我想这些jar更有可能是某种依赖项。然后你可以这样做：

configurations {
    // configuration that holds jars to copy into lib
    extraLibs
}
dependencies {
    extraLibs 'org.something:something-dep1:version'
    extraLibs 'org.something:something-dep2:version'
}

jar {
    into('lib') {
        from configurations.extraLibs
    }
}

Answer 2

逐字摘自：http://docs.codehaus.org/display/GRADLE/Cookbook #Cookbook-Creatingafatjar

Gradle 0.9：

jar {
    from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}

Gradle 0.8：

jar.doFirst {
    for(file in configurations.compile) {
        jar.merge(file)
    }
}

上面的代码片段将仅包含该项目的编译依赖项，而不包含任何可传递的运行时依赖项。如果您还想合并它们，请将configurations.compile 替换为configurations.runtime。

编辑：仅选择您需要的 jar

进行新配置，releaseJars 可能

configurations {
    releaseJars
}

将您想要的 jar 添加到该配置中，

dependencies {
    releaseJars group: 'javax.mail', name: 'mail', version: '1.4'
    //etc
}

然后在上面概述的 jar 任务中使用该配置。

Answer 3

简单：

task copyToLib( type: Copy ) {
    into "$buildDir/libs/lib"
    from configurations.runtime
}

jar { dependsOn copyToLib }

运行它：

$ gradle jar
...
$ tree build/libs

build/libs
├── your-project-0.0.1.BUILD-SNAPSHOT.jar
└── lib
    ├── akka-actor-2.0.jar
    ├── akka-camel-2.0.jar
    ├── ... ... ...
    ├── spring-expression-3.1.0.RELEASE.jar
    └── zmq-2.1.9.jar

1 directory, 46 files

Answer 4

我还需要做类似的事情，但不太能够得到 Guus 和 stigkj 建议的工作，但在他们的帮助下足够接近以使其工作（Guus 的示例在 dependency {compile {extendsFrom myLibs 上爆炸了） 然后运行 ​​gradle jar 并检查创建的 jar 给出了这个

apply plugin: 'groovy'

repositories {
    mavenCentral()
}

configurations {
    // custom config of files we want to include in our fat jar that we send to hadoop
    includeInJar
}

dependencies {
    includeInJar 'org.codehaus.groovy:groovy:1.8.6'

    configurations.compile.extendsFrom(configurations.includeInJar)
}

jar {
    into('lib') {
        println "includeInJar: " + configurations.includeInJar.collect { File file -> file }
        from configurations.includeInJar
    }

}

输出，表明我得到的 jar 文件具有 groovy 以及它所依赖的所有 jar。在“胖罐子”里面：

Answer 5

下面的代码可以尝试一下。它取决于jar任务并且是Jar类型

task createJobJar(dependsOn:jar,type:Jar) {
    manifest {
        attributes(
                "Implementation-Title": 'Job '
                ,"Implementation-Version": version
        )
    }
    classifier 'job'
    destinationDir new File("$buildDir")
    into('libs'){
         from configurations.compile
    }
    into('classes'){
        from "$buildDir/classes"
    }
    into('resources'){
        from "$projectDir/src/main/resources"
    }
    into('scripts'){
        from "$projectDir/src/main/scripts"
    }
}

上面的代码将不同的内容打包到不同的目录中。

Answer 6

我需要你问的同样的事情，并使用了这种方法。您可能不需要自定义配置声明，但我需要将本地使用的 jar 文件与超级构建文件中声明的文件分开。

configurations{
    //declare custom config if necessary, otherwise just use compile
    myLibs
}
dependencies {
    //add lib/*.jar files to myLibs
    myLibs fileTree(dir: 'lib', include: '*.jar')
    compile {
        //set compile configuration to extend from myLibs
        extendsFrom myLibs
    }
}
// task to copy libs to output/lib dir
task copyToLib(type: Copy) {
    into "$buildDir/output/lib"
    from configurations.myLibs
}

jar {
    //include contents of output dir
    from "$buildDir/output"
    manifest {
        //...
    }
}

//set build task to depend on copyToLib
build.dependsOn(copyToLib)

Answer 7

我也有同样的问题。我这样解决了：

使用 copyToLib 将文件复制到 lib 文件夹中，并使用类路径引用依赖项

ext.mainClass = 'test.main'

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.google.code.gson:gson:2.8.2'
    //....
}

jar {
    from "$buildDir/libs/lib"
    manifest {
        attributes 'Main-Class': 'test.main',
        'Class-Path': configurations.compile.collect { 'lib/'+it.getName() }.join(' ')
    }
}

task copyToLib(type: Copy) {
    into "$buildDir/libs/lib"
    from configurations.compile
}

build.dependsOn(copyToLib)

Answer 8

就我而言，我需要将根项目 Jar 的内容包含到子项目 Jar 中。因此，为了使其工作，可以使用此模板：

jar{
  manifest{
    attributes 'Main-Class':'<main class>'
  }
  def conf= configurations.find {it.name.equals('compile') }
  File jar= conf.files.find {it.name.contains('<name or part of the name of produced Jar>')}

  FileTree fileTree=zipTree(jar)
  from fileTree
}

我的示例：

jar{
   manifest{
       attributes 'Main-Class':'alexiy.jace.Jace'
   }
   description='Make a runnable API Jar'
   def conf= configurations.find {it.name.equals('compile') }
   File tools= conf.files.find {it.name.contains('Tools')}

   FileTree fileTree=zipTree(tools)
   from fileTree
}

Answer 9

以下是我如何使用 Gradle 实现此构建设置。这会将您的应用程序构建到 Jar 中，将生成的库 jar 复制到 build/libs 下的 libs 目录中，并配置类路径以将 jar 包含在创建的 build/libs/libs 目录中。

 plugins {
    id 'application'
 }

 group 'org.pkg'
 version '1.0-SNAPSHOT'

 ext.mainClass = 'org.pkg.MainClass'

 repositories {
    mavenCentral()
    mavenLocal()
 }

 dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile group: 'junit', name: 'junit', version: '4.12'

    implementation group: 'com.mchange', name: 'c3p0', version: '0.9.5.5'
 }
 
 task copyToLib(type: Copy) {
    into "$buildDir/libs/libs"
    // configurations.runtimeClasspath includes maven jars
    from configurations.runtimeClasspath 
 }

 def archiveVersion = "1.0.0"

 task uberJar(type: Jar) {
    archiveClassifier = 'uber'

    from sourceSets.main.output
    // include the copy task
    dependsOn(copyToLib)

    // use onfigurations.runtimeClasspath to collect all the jars
    manifest {
      attributes(
            'Class-Path': configurations.runtimeClasspath.collect { 'libs/' + it.getName() }.join(' '),
            'Main-Class': 'org.pkg.MainClass',
            "Implementation-Title": "Gradle",
            "Implementation-Version": archiveVersion
      )
    }
 }

Answer 10

task <taskname>(type: Jar) {
    archiveName 'nameofjar.jar'
    doFirst {
    manifest {
            attributes 'Class-Path': configurations.compile.files.collect{ project.uri(it) }.join(' ')
        }
    }
}
