我正在尝试gradle并尝试建立一个构建应用程序不同风格(品牌)的系统,该系统主要因配置而异。到目前为止,我有两个版本的构建脚本-都无法正常工作。
版本1
将第一个特定于 flavor 的资源文件夹flavor-res
添加到sourcesets
,它实现了覆盖某些默认资源的功能。任务规则为每种口味定义任务,(理想情况下)应触发整个 jar 的构建。
这样可以很好地工作,并一次生成一种口味的所需 jar ,例如
gradle clean flavorOne
但是如果我这样做,
shadowJar
任务只运行一次gradle clean flavorOne flavorTwo
精简脚本:
sourceSets {
main {
...
resources {
srcDirs = ['src/main/resources', "${project.buildDir}/flavor-res/"]
}
}
}
shadowJar { classifier = 'SNAPSHOT' }
tasks.addRule("Pattern: flavor<Name>") { String taskName ->
if (taskName.startsWith("flavor")) {
String flavorName = (taskName - "flavor")
String flavorOutDir = "${project.buildDir}/${flavorName}"
// Set output folder and jar name
task("${taskName}Configure") {
outputs.dir(flavorOutDir)
doFirst {
archivesBaseName = flavorName
project.buildDir = flavorOutDir
}
}
// Copy res to folder used in sourcesets
task("${taskName}CopyResources") {
mustRunAfter = ["${taskName}Configure"]
outputs.dir("${project.buildDir}/flavor-res")
doFirst {
copy {
from "flavors/${flavorName}/"
into "${project.buildDir}/flavor-res/"
}
}
}
shadowJar.mustRunAfter = ["${taskName}Configure", "${taskName}CopyResources"]
// Define task that depends on shadowJar
task(taskName, dependsOn: ["${taskName}Configure", "${taskName}CopyResources",
shadowJar]) {
println "Configuring ${taskName}"
}
}
感觉到它可能不起作用,因为更改检测某种程度上不起作用,我尝试了一种替代方法。这是脚本的简化版本
版本2
修改了规则,以为每种 flavor 定义
shadowJar
动态任务。/* Removed sourceSets in this version */
shadowJar { classifier = 'SNAPSHOT' }
tasks.addRule("Pattern: flavor<Name>") { String taskName ->
if (taskName.startsWith("flavor")) {
String flavorName = (taskName - "flavor")
String flavorOutDir = "${project.buildDir}/${flavorName}"
// Set resources for main sourceset
task("${taskName}Configure") {
outputs.dir(flavorOutDir)
doFirst {
archivesBaseName = flavorName
sourceSets.main.resources.srcDirs = ['src/main/resources', "${flavorOutDir}/flavor-res"]
project.buildDir = flavorOutDir
}
}
task("${taskName}CopyResources") {
outputs.dir("${flavorOutDir}/flavor-res")
dependsOn "${taskName}Configure"
doFirst {
copy {
from "flavors/${flavorName}/"
into "${project.buildDir}/flavor-res/"
}
}
}
// This should shadowJar for each flavor - but generate jars dont have the required artifacts.
task ("${taskName}Build", type: ShadowJar) {
from sourceSets.main.output
configurations = [ configurations.runtime ]
classifier = 'SNAPSHOT'
dependsOn "${taskName}CopyResources"
}
task(taskName, dependsOn: ["${taskName}Build"]) {
}
}
}
但是,现在,生成的jar格式不正确。第一种口味仅获得主要的人工制品,但没有显示出 jar 。第二个 jar 只有 list ,没有其他东西。
实现该目标的正确方法是什么?
PS:不,它不是android应用程序( flavor 只是品牌的同义词)。
最佳答案
我决定重新创建一个 flavor 构建脚本,因为它可以简化为您现在所拥有的。 ShadowJar
任务本身可以处理所有类和资源的复制,无需定义单独的类和资源。我还采用了一些默认配置,该配置将应用于shadowJar
任务,并将其应用于自定义ShadowJar
任务以获得相同的行为。
我首先建立一个快速测试项目结构,可以在这里找到:
Test Structure
然后我想出了以下脚本:
import com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar
plugins {
id 'java'
id "com.github.johnrengelman.shadow" version "2.0.4"
}
group 'your-group'
version 'dev-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
// Example dependency
compile group: 'com.google.guava', name: 'guava', version: '19.0'
}
tasks.addRule("Pattern: flavor<Name>") { def taskName ->
if (!taskName.startsWith("flavor")) {
return
}
def flavorName = taskName - "flavor"
// Define the shadow task
def shadowTask = task ("${flavorName}ShadowJar", type: ShadowJar) {
classifier = flavorName
// Add our flavor resources, first to prioritize these resources
from file("src/main/flavors/${flavorName}")
// Include our project classes
from project.sourceSets.main.output
// Don't include duplicate resources, only the first ones added, in
// this case the flavored resources will override the default ones
duplicatesStrategy = DuplicatesStrategy.EXCLUDE
// Some defaults taken from the default shadowJar task
// https://github.com/johnrengelman/shadow/blob/master/src/main/groovy/com/github/jengelman/gradle/plugins/shadow/ShadowJavaPlugin.groovy#L48
configurations = [ project.configurations.runtime ]
manifest.inheritFrom project.tasks.jar.manifest
exclude('META-INF/INDEX.LIST', 'META-INF/*.SF', 'META-INF/*.DSA', 'META-INF/*.RSA')
}
// Define the flavor task
task ("${taskName}", dependsOn: shadowTask) {}
}
