Gradle排除依赖项中的特定文件 [英] Gradle exclude specific files inside dependency

问题描述

我想知道是否有任何方法要排除特定文件，这些文件位于依赖项（不是传递依赖项）中，不会被下载。

I was wondering if there was anyway to exclude specific files,that are inside a dependency (not a transitive dependency), from being downloaded.

我正在将一个构建从Ant + Ivy切换到Gradle，这是在Ivy之前完成的。我问，因为我有一个依赖包含Artifactory中的许多已编译的wsdl jar我们正在下拉，但我不想下载依赖项中的所有jar。

I am switching a build from Ant + Ivy to Gradle and this was done with in Ivy before. I ask because I have a single dependency that contains many compiled wsdl jars in Artifactory that we are pulling down, but I do not want to download all of the jars in the dependency.

在Ivy中它的设置如下：

In Ivy it was setup like:

这6个工件发布到Artifactory到一个目录repo / dep.location / example / 7.3 / jar。

These 6 artifacts are published to Artifactory in to one directory repo/dep.location/example/7.3/jar.

<publications>
    <artifact name="foo-1-0" type="jar" />
    <artifact name="foo-1-0-async" type="jar" />
    <artifact name="foo-1-0-xml" type="jar" />
    <artifact name="bar-1-0" type="jar" />
    <artifact name="bar-1-0-async" type="jar" />
    <artifact name="bar-1-0-xml" type="jar" />
</publications>

这就是我只检索六个工件中的两个的方法。

This is how I retrieve only two of the six artifacts.

<dependency org="dep.location" name="example" rev="7.3"
            conf="compile,runtime">
    <include name="foo-1-0-async"/>
    <include name="foo-1-0-xml"/>
</dependency>

目前，如果我尝试在Gradle中执行类似的操作，则会忽略排除并下载所有六个工件。

Currently if I attempt to do something similar in Gradle the excludes are ignored and all six artifacts are downloaded.

compile (group:"dep.location", name:"example", version:"7.3")
{
    exclude module:'foo-1-0-xml'
    exclude module:'bar-1-0'
    exclude module:'bar-1-0-async'
    exclude module:'bar-1-0-xml'
}

我正在使用Gradle版本1.8。

I am using Gradle version 1.8.

推荐答案

我不认为Gradle有任何内置支持来完成此任务，但你可以清理文物你自己从类路径出来。

I don't think Gradle has any built in support for accomplishing this, but you can clean the artifacts out from the classpath yourself.

灵感来自这个主题我想出了这个：

Inspired by this thread on the Gradle forums I came up with this:

// The artifacts we don't want, dependency as key and artifacts as values
def unwantedArtifacts = [
    "dep.location:example": [ "foo-1-0-xml", "bar-1-0", "bar-1-0-async", "bar-1-0-xml"],
]

// Collect the files that should be excluded from the classpath
def excludedFiles = configurations.compile.resolvedConfiguration.resolvedArtifacts.findAll {
    def moduleId = it.moduleVersion.id
    def moduleString = "${moduleId.group}:${moduleId.name}:${moduleId.version}" // Construct the dependecy string
    // Get the artifacts (if any) we should remove from this dependency and check if this artifact is in there
    it.name in (unwantedArtifacts.find { key, value -> moduleString.startsWith key }?.value)
}*.file

// Remove the files from the classpath
sourceSets {
    main {
        compileClasspath -= files(excludedFiles)
    }
    test {
        compileClasspath -= files(excludedFiles)
    }
}

请注意，Gradle可能仍会下载文件并为您缓存它们，但它们不应该在您的类路径中。

Note that Gradle will probably still download the files and cache them for you, but they should not be in your classpath.
