具有多个应用程序的分级根项目

Question

如何使用多个使用相同库的应用程序创建gradle根项目。我希望以包含以下内容的tar和zip文件结束：

RootProject/
  bin/
    Command1
    Command2
    ...
  lib/
    Library.jar
    ..

RootProject/
  settings.gradle
  build.gradle
  common.gradle
  Library/
    build.gradle
    src/main/java/Library.java
  Command1/
    build.gradle
    src/main/java/Command1.java
  Command2/
    build.gradle
    src/main/java/Command2.java

apply plugin: 'base' // To add "clean" task to the root project.

allprojects {
    repositories {
        mavenCentral();
    }
}

subprojects {
    apply plugin: 'java'

    group = 'edu.csusb.ecs.gmailsettings'
    version = '1.0-SNAPSHOT'

    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.10'
    }
}

task build(type: Copy) {
    dependsOn subprojects.build
    from subprojects.collect { it.tasks.withType(Jar) }
    into project.rootProject.buildDir.toString() + "/libs"
}

task clean(group:project.rootProject.ext.group, type: Delete, description:"clean jars from subprojects") {
    delete fileTree(project.buildDir).include('**/*')
}

导致错误

Answer 1

在我的根项目build.gradle中，我定义了一个任务，将所有子项目jar文件复制到根项目的/build/libs文件夹中，如下所示：

task build(type: Copy) {
    dependsOn subprojects.build
        // from subprojects.collect { it.tasks.withType(AbstractArchiveTask) }
        from subprojects.collect { it.tasks.withType(Jar) }
        into project.rootProject.buildDir.toString() + "/libs"
}

task clean(group:project.rootProject.ext.group, type: Delete, description:"clean jars from subprojects") {
    delete fileTree(project.buildDir).include('**/*')
}

您应该能够以类似的方式将任何其他构建人工制品复制到根项目。
