在gradle中-如何将jar嵌入lib目录(特别是lib / enttoolkit.jar和lib / mail.jar)的build输出jar中?
Answers:
从以下网址逐字删除:http : //docs.codehaus.org/display/GRADLE/Cookbook#Cookbook-Creatingafatjar
摇篮0.9:
jar {
from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
摇篮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,而不包含任何传递性运行时依赖项。如果您还希望合并它们,请用configuration.runtime替换configuration.compile。
编辑:只选择您需要的罐子
进行新的配置,也许发布Jars
configurations {
releaseJars
}
将您想要的罐子添加到该配置
dependencies {
releaseJars group: 'javax.mail', name: 'mail', version: '1.4'
//etc
}
然后在上述jar任务中使用该配置。
如果您的项目中的所有jar都位于目录中(称为libs
),则只需要这样做:
jar {
into('lib') {
from 'libs'
}
}
我猜这些罐子很可能是某种依赖。然后,您可以这样做:
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
}
}
configurations.runtime
,从而为您提供默认的compile
依赖关系,从而省去了创建自己的extraLibs
配置的麻烦。
configurations.runtimeClasspath
不是从中进行复制configurations.runtime
,同时避免了对extraLibs
定义的需求。
srcDirs
processResources{ from(zipTree("src/main/resources/lib/local-jar-name.jar")) }
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
我还需要做类似的事情,但并不能完全按照Guus和stigkj的建议工作,但是在他们的帮助下,他们已经足够亲密,以使这项工作正常进行(Guus的例子dependencies { compile { extendsFrom myLibs }}
对我来说是封闭的。
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,这将为我提供输出,显示我得到的jar文件具有Groovy以及它依赖于“胖jar”内部的所有jar:
% gradle jar
includeInJar: [/Users/tnaleid/.gradle/caches/artifacts-8/filestore/org.codehaus.groovy/groovy/1.8.6/jar/553ca93e0407c94c89b058c482a404427ac7fc72/groovy-1.8.6.jar, /Users/tnaleid/.gradle/caches/artifacts-8/filestore/antlr/antlr/2.7.7/jar/83cd2cd674a217ade95a4bb83a8a14f351f48bd0/antlr-2.7.7.jar, /Users/tnaleid/.gradle/caches/artifacts-8/filestore/asm/asm/3.2/jar/9bc1511dec6adf302991ced13303e4140fdf9ab7/asm-3.2.jar, /Users/tnaleid/.gradle/caches/artifacts-8/filestore/asm/asm-tree/3.2/jar/cd792e29c79d170c5d0bdd05adf5807cf6875c90/asm-tree-3.2.jar, /Users/tnaleid/.gradle/caches/artifacts-8/filestore/asm/asm-commons/3.2/jar/e7a19b8c60589499e35f5d2068d09013030b8891/asm-commons-3.2.jar, /Users/tnaleid/.gradle/caches/artifacts-8/filestore/asm/asm-util/3.2/jar/37ebfdad34d5f1f45109981465f311bbfbe82dcf/asm-util-3.2.jar, /Users/tnaleid/.gradle/caches/artifacts-8/filestore/asm/asm-analysis/3.2/jar/c624956db93975b7197699dcd7de6145ca7cf2c8/asm-analysis-3.2.jar]

Exception in thread "main" java.lang.NoClassDefFoundError: com/rabbitmq/client/ConnectionFactory
。我应该以某种方式设置classpath吗?
下面的代码可以尝试。它取决于jar任务,属于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"
}
}
上面的代码会将不同的内容包装在不同的目录中。在gradle 2.2上测试
我需要跟您问的一样,并使用了这种方法。您可能不需要自定义配置声明,但是我需要将本地使用的jar文件与在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)
我有同样的问题。我这样解决了:
使用copyToLib将文件复制到lib文件夹中,并使用Class-Path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)
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,要使其工作,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
}
我的例子:
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
}
这是我使用Gradle设法实现此构建设置的方法。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。

id 'application'

archiveClassifier = 'uber'

dependsOn(copyToLib)
// use onfigurations.runtimeClasspath to collect all the jars
