Java gradle中的条件依赖

我正在使用gradle进行多项目构建。 我有一个在命令行中注入属性的条件的要求

情景1：

        dependencies {

            if( ! project.hasProperty("withsources")){


             compile 'com.xx.yy:x-u:1.0.2'

            }else{
              println " with sources"
              compile project (':x-u')
            }

        }

1.每当我执行渐变运行-Pwithsources

    it is printing "withsources" 

    it is not printing "withsources" 

二,。但是对于gradle run

    it is printing "withsources" 

    it is not printing "withsources" 

情景2：

        dependencies {

            if(  project.hasProperty("withsources")){


             compile 'com.xx.yy:x-u:1.0.2'

            }else{
              println " with sources"
              compile project (':x-u')
            }

        }

1.每当我执行渐变运行-Pwithsources

    it is printing "withsources" 

    it is not printing "withsources" 

二,。但是对于gradle run

    it is printing "withsources" 

    it is not printing "withsources"

我不知道它总是转到其他循环。任何人都可以在这里提供帮助。

如果没有看到完整的构建，我真的无法说出您的问题所在。gradle但是您的一般方法是正确的

下面是一个对我有用的小例子：

plugins {
    id "java"
}

repositories {
    jcenter()
}

dependencies {
    if (project.hasProperty("gson")) {
        implementation "com.google.gson:gson:2.8.5"
    } else {
        implementation "org.fasterxml.jackson.core:jackson-core:2.9.0"
    }
}

无财产：

$ gradle dependencies --configuration implementation
:dependencies

------------------------------------------------------------
Root project
------------------------------------------------------------

implementation - Implementation only dependencies for source set 'main'. (n)
\--- org.fasterxml.jackson.core:jackson-core:2.9.0 (n)

(n) - Not resolved (configuration is not meant to be resolved)

您是否可能在其他地方定义了资源？例如？

请忽略这是我的错误，没有检查gradle.properties听起来像你想要的。由于复合构建是在groovy中声明的，所以这可能是有条件的
