Gradle 在目录中包含传递依赖项

[英]Gradle include transitive dependencies in directory

我有一个 java 项目,它有几个依赖项,例如:

dependencies {
    compile("com.whatever.jar:jar-1:1.2.3")
    compile("com.whatever.jar:jar-2:4.5.6")
    compile("com.whatever.jar:jar-3:7.8.9")
} 

我将 package 作为 jar 库并将其与描述这些依赖项的 POM 文件一起发布到存储库:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.my.project</groupId>
    <artifactId>my-library</artifactId>
    <version>1.0.0</version>
    <dependencies>
        <dependency>
            <groupId>com.whatever.jar</groupId>
            <artifactId>jar-1</artifactId>
            <version>1.2.3</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>com.whatever.jar</groupId>
            <artifactId>jar-2</artifactId>
            <version>4.5.6</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>com.whatever.jar</groupId>
            <artifactId>jar-3</artifactId>
            <version>7.8.9</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>
</project>

我还有另一个项目,它依赖于之前在编译时构建的 jar:

dependencies {
    compileOnly("com.my.project:my-library:1.0.0")
}

我想创建一个任务来构建第二个项目并创建一个 zip 文件,其中包含com.my.project:my-library:1.0.0 jar 及其依赖项( jar-1 jar-2 -3-1 jar-3 ) .

task createZip << {
    into('lib') {
        // here I would like to do something like (it's a horrible pseudo-code):
        from configurations.(com.my.project:my-library:1.0.0).jar.transitiveDependencies.files
    }
}

我该如何做到这一点?

编辑:我还想以编程方式访问my-library的传递依赖项列表(确切地说是那些,而不是项目中的任何其他依赖项),以便使用它们构建Loader-Path清单属性。

task uberJar(type: Jar) {
   dependsOn classes
   from sourceSets.main.runtimeClasspath.collect { it.directory?fileTree(it):zipTree(it)}
   classifier = 'uber-jar'
} 
assemble.dependsOn uberJar

这是一个自包含的build.gradle脚本,它演示了如何创建您的createZip任务(仅将特定依赖项添加到 ZIP 存档):

/* make the "compileOnly" configuration available */
plugins {
    id 'java'
}

/* add some demo dependencies to the project */
repositories {
    jcenter()
}
dependencies {
    compileOnly 'junit:junit:4.12'
    compileOnly 'org.slf4j:slf4j-simple:1.7.28'
}

task createZip(type: Zip) {
    // the "lib" directory in the ZIP file will only have all those dependency
    // files of the "compileOnly" configuration which belong to the
    // "junit:junit:4.12" module:
    def depOfInterest = dependencies.create('junit:junit:4.12')
    into('lib') {
        from configurations.compileOnly.resolvedConfiguration.getFiles({dep ->
            dep == depOfInterest
        })
    }

    // the "justForDemonstration" directory in the ZIP file will have all
    // dependency files of the "compileOnly" configuration, incl. SLF4J:
    into('justForDemonstration') {
        from configurations.compileOnly
    }
}

这可以使用./gradlew createZip运行(使用 Gradle 5.6.2 测试)。 它在build/distributions/<your_project_name>.zip下生成 ZIP 文件。 让我知道这是否是您对伪代码的想法。
