gradle - 我如何用其他jar中的lib目录构建一个jar？

Question

在gradle中 - 我如何在lib目录(特别是lib/enttoolkit.jar和lib/mail.jar)中的jar输出jar中嵌入jar？

Answer 1

逐字解读: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)
    }
}

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

编辑:只选择你需要的罐子

做一个新的配置,releaseJars也许吧

configurations {
    releaseJars
}

将所需的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 2

如果libs项目中的目录中有所有jar(让我们调用它),您只需要:

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

我想这些罐子更有可能是某种依赖.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 3

简单:

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

jar { dependsOn copyToLib }

运行:

$ 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

我也需要做类似的事情并且不能完全得到Guus和stigkj建议的工作,但是在他们的帮助下得到了足够的接近才能使这个工作(Guus的例子dependencies { compile { extendsFrom myLibs }}为我打破了关闭.

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
    }

}

然后运行gradle jar并检查创建的jar给了我这个输出,显示我得到了jar文件,以及它依赖于"fat jar"内的所有jar文件:

%  gradle jar

Answer 5

可以尝试下面的代码.它取决于jar任务,属于Type Jar

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"
    }
}

上面的代码将在不同的目录中打包不同的内容.在gradle 2.2上测试

我需要你提出的相同的事情,并使用这种方法.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jar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)
