Gradle排除依赖项内的特定文件

Question

<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>

<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，如果我试图在Gradle中做类似的事情，排除将被忽略，并且下载所有六个工件。

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'
}

我使用的是Gradle版本1.8。

我不认为Gradle有任何内置的支持来完成这一点，但您可以自己从类路径中清除工件。

受Gradle论坛上这条线程的启发，我想出了这个：

// 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)
    }
}

注意，Gradle可能仍然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。
