Question

我有两个子项目subproject1和subproject2。我想将一些类从subproject2添加到subproject1并获取subproject1.jar。以下是我的gradle文件：

task copyClasses (dependsOn: [  ':subproject1:clean',  ':subproject1:classes']) {
    println "copyClasses "
    doLast {
        Task study = tasks.getByPath(':subproject1:jar')
        study.doFirst {
            copy {
                println "copy ... "
                println sourceSets.main.output.classesDir
                println project(':subproject1').sourceSets.main.output.classesDir
                from sourceSets.main.output.classesDir
                into project(':subproject1').sourceSets.main.output.classesDir
            }
        }
    }
}

task jarUpdated (dependsOn: [ clean, classes, copyClasses, ':subproject1:jar']) {
    doLast {
        println "jarUpdated"
    }
}

但是我得到了如下构建序列：

$ gradle jarUpdated
copyClasses
:subproject1:compileJava
:subproject1:processResources UP-TO-DATE
:subproject1:classes
:subproject1:jar
:subproject2:compileJava
:subproject2:processResources UP-TO-DATE
:subproject2:classes
:subproject2:clean
:subproject1:clean
:subproject2:copyClasses
Calling Task.doFirst(Closure) after task execution has started has been deprecated and is scheduled to be removed in Gradle 2.0. Check the configuration of task ':subproject1:jar'.
:subproject2:jarUpdated
jarUpdated

BUILD SUCCESSFUL

我的期望是：

$ gradle jarUpdated
:subproject2:clean 
:subproject2:compileJava
:subproject2:processResources UP-TO-DATE
:subproject2:classes
:subproject1:clean 
:subproject1:compileJava
:subproject1:processResources UP-TO-DATE
:subproject2:copyClasses
copyClasses
copy ... 
:subproject1:jar 
:subproject2:jarUpdated
jarUpdated

BUILD SUCCESSFUL

请您建议或指出我错过了什么？非常感谢！

最简单的＆＃34;在你的subproject1构建文件中完全按照你要求做的方式可能是这样的。

jar {
  from  tasks.getByPath(':subproject2:compileJava')
}

然而，这是一个非常简单的方法，有很多警告，例如

子项目1无法针对子项目2类进行编译
不包含子项目2的任何依赖项
等

我实际上建议将subproject2声明为subproject1的依赖项并使用Peter建议的其中一个插件。

Gradle依赖不能满足我的期望
