我正在使用gradle进行多项目构建。
我有一个要求选择依赖项取决于在命令行中注入(inject)的属性的条件。
方案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 gradle run -Pwithsources
it is printing "withsources"
2.但是对于 gradle，请运行
it is printing "withsources"
方案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 gradle run -Pwithsources
it is not printing "withsources"
2.但是对于 gradle，请运行
it is not printing "withsources"
我不知道它总是进入其他循环。任何人都可以在这里提供帮助。
最佳答案
在看不到完整的build.gradle之前，我无法真正地说出您的问题所在，但您的一般做法是正确的。
这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"
}
}
无属性(property):
$ 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)
BUILD SUCCESSFUL in 0s

带有属性:
$ gradle -Pgson dependencies --configuration implementation
:dependencies
------------------------------------------------------------
Root project
------------------------------------------------------------
implementation - Implementation only dependencies for source set 'main'. (n)
\--- com.google.gson:gson:2.8.5 (n)
(n) - Not resolved (configuration is not meant to be resolved)
BUILD SUCCESSFUL in 0s
1 actionable task: 1 executed
您是否有可能在其他地方定义了withsources？像gradle.properties中一样？
