gradle - 转换maven jar并将资源插件复制到gradle

Question

我是gradle的新手，正在尝试将我的POM转换为gradle.build。我已经转换了依赖关系部分，现在正在转换插件部分。我的POM中有关注者

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>

                            <include>**/*.xml</include>
                            <include>**/*.vm</include>
                            <include>**/*.txt</include>
                        </includes>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

当我运行这个POM时，我得到了这样的结构







现在我用gradle jar任务尝试了以下内容

apply plugin: 'application' // implicitly apply java and distribution plugin
apply plugin: 'eclipse'

sourceCompatibility = 1.8
targetCompatibility = sourceCompatibility
mainClassName = "com.softech.ls360.integration.BatchImport"
version = '1.0'

ext {
    log4jGroupId = "org.apache.logging.log4j"
    springFrameworkGroupId = "org.springframework"
    springFrameworkVersion = "4.2.4.RELEASE"
    junitVersion = "4.12"
    ....
}

dependencies {
    compile group: log4jGroupId, name: 'log4j-api', version: log4jVersion
    ....
    runtime group: 'org.jboss.logging', name: 'jboss-logging', version: jbossLoggingVersion
    ....
    testCompile group: 'junit', name: 'junit', version: junitVersion
}

jar {

    // Keep jar clean:
    exclude '**/*.properties', '**/*.xml', '**/*.vm', '**/*.txt'

    //from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    manifest { 
       attributes ('Implementation-Version': version,
           'Main-Class': "$mainClassName",
           'Class-Path': "conf/" + " " + configurations.runtime.files.collect {"dependency-jars/$it.name" }.join(' ')
       )
    }
}

然后我得到了下面的 jar



它在jar中生成适当的类路径。但是build/libs/文件夹仅包含jar，其中没有dependency-jars和conf文件夹。我如何创建这些文件夹，所以当我运行任务jar时，它将在build/libs/文件夹中创建jar，还创建其中包含所有jar的dependency-jars文件夹。还有conf中的build/libs文件夹，以及.propeties, .xml, .vm, .txt文件夹中的所有src/main/resources/文件。

谢谢

Answer 1

嗯，我尝试了以下方法，并且有效。我不知道这种方法有多好。但是，如果有人有更好的方法，那么也请发布答案。

....
task wrapper(type: Wrapper) {
    gradleVersion = '2.10'
}

task copyJars(type: Copy) {
    from configurations.runtime
    into "$buildDir/libs/dependency-jars"
}

task copyConfigurationFiles(type: Copy) {
    description 'Copies the configurations files src/main/resources directory (from) to the target directory(into).'
    from "src/main/resources"
    into "$buildDir/libs/conf"
    include '**/*.properties', '**/*.xml', '**/*.vm', '**/*.txt'
}

task copyFiles(dependsOn: [copyJars, copyConfigurationFiles])

jar {

    dependsOn copyFiles

    // Keep jar clean:
    exclude '**/*.properties', '**/*.xml', '**/*.vm', '**/*.txt'

    manifest { 
        attributes ('Implementation-Version': version,
           'Main-Class': "$mainClassName",
           'Class-Path': "conf/" + " " + configurations.runtime.files.collect {"dependency-jars/$it.name" }.join(' ')
       )
    }
}

之后，我只需运行任务jar。它创建了jar，以及其中包含所有jar的dependency-jars文件夹，以及其中包含所有配置文件的conf文件夹。就像我做maven install一样

谢谢
