相关疑难解决方法(0)

我正在尝试在多个Gradle任务中重用通用逻辑,类似于本答案中建议的,但是我遇到了额外的项目属性不可见的问题.

归结起来,这就是问题所在.假设我有一个根Gradle构建脚本,build.gradle它设置了一个额外的项目属性,

project.ext.myProp = 'myValue'

我有一个子项目settings.gradle,

include 'subproject'

子项目定义并使用引用该额外项目属性的自定义任务,

class CustomTask extends DefaultTask {
    CustomTask() {
        doFirst {
            println project.ext.myProp
        }
    }
}

task custom(type: CustomTask) {
    println 'custom task'
}

执行这个给了我这个:
