复制依赖关系，排除某些配置 [英] Copy dependencies excluding some configuration

问题描述

假设一个这样的项目布局：

Suppose a project layout like this:

allprojects {
    apply plugin: "java"

    configurations {
        provided
        compile.extendsFrom(provided)
    }
}

project("a") {
    dependencies {
        compile("foo:bar:1.0")
        ...
        provided("bar:baz:3.14")
        ...
    }
}

project("b") {
    dependencies {
        compile("abc:def:1.0")
        ...
        provided("xyz:foo:3.14")
        ...
    }
}

dependencies {
    compile(project(":a"))
    compile(project(":b"))
}

现在，我需要一个任务，将根目录的所有依赖关系（可传递地）复制到某个目录，但不包括提供的配置。我怎么能做到这一点？

Now, I need a task that will copy all the dependencies of root project (transitively) to some directory, but excluding the provided configuration. How can I do this?

推荐答案

对此有点痴迷并试图找出如何做到这一点。我用它来处理下面的gradle文件。

Was a little obsessed with this and tried to figure out how to do it. I got it to work with the following gradle file. Note the configurations part and where I copy the dependencies.

allprojects {
    apply plugin: "java"

    configurations {
        provided
    }

    sourceSets {
        main { 
            compileClasspath += configurations.provided 
        }
    }

    repositories {
        mavenCentral()
    }
}

project("a") {
    dependencies {
        compile("jdom:jdom:1.0")
        provided("javax.servlet:servlet-api:2.5")
    }
}

project("b") {
    dependencies {
        compile("javax.jcr:jcr:2.0")
        provided("commons-logging:commons-logging:1.0")
    }
}

dependencies {
    compile(project(":a"))
    compile(project(":b"))
}

task copyDependencies(type:Copy) {
    from configurations.compile
    into 'build/dependencies'
}

我认为这是解决这个问题的更简单的方法，但没有弄明白。但是这个工作。唯一的问题是，您必须将所提供的配置添加到idea / eclipse classpath中，以使ide集成能够正常工作。

I think it's a simpler solution to this problem, but did not figure it out. But this one works. The only thing is that you have to add provided configuration to idea/eclipse classpath too to make the ide integration work as espected.
