使用项目属性覆盖插件约定属性
我试图了解如何从项目属性设置插件约定属性。
这是来自 gradle 发行版的 customPluginWithConvention 示例 (gradle-0.9.2\samples\userguide\organizeBuildLogic\customPluginWithConvention\build.gradle)
apply plugin: GreetingPlugin
greeting = 'Hi from Gradle'
class GreetingPlugin implements Plugin<Project> {
def void apply(Project project) {
project.convention.plugins.greet = new GreetingPluginConvention()
project.task('hello') << {
println project.convention.plugins.greet.greeting
}
}
}
class GreetingPluginConvention {
def String greeting = 'Hello from GreetingPlugin'
}
在没有项目属性的情况下运行此脚本：
>gradle hello
:hello
Hi from Gradle
BUILD SUCCESSFUL
现在尝试通过设置项目属性来设置自定义消息：
>gradle -Pgreeting=goodbye hello
:hello
Hello from GreetingPlugin
显示约定的默认问候语，而不是预期的“再见”。是否可以覆盖该消息？
I am trying to understand how to set a plugin convention property from a project property.
Here is the customPluginWithConvention example from the gradle distribution (gradle-0.9.2\samples\userguide\organizeBuildLogic\customPluginWithConvention\build.gradle)
apply plugin: GreetingPlugin
greeting = 'Hi from Gradle'
class GreetingPlugin implements Plugin<Project> {
def void apply(Project project) {
project.convention.plugins.greet = new GreetingPluginConvention()
project.task('hello') << {
println project.convention.plugins.greet.greeting
}
}
}
class GreetingPluginConvention {
def String greeting = 'Hello from GreetingPlugin'
}
Running this script with no project property:
>gradle hello
:hello
Hi from Gradle
BUILD SUCCESSFUL
And now trying to set a custom message via setting a project property:
>gradle -Pgreeting=goodbye hello
:hello
Hello from GreetingPlugin
Instead of the expected "goodbye" the default greeting of the convention is shown. Is it possible to override the message?
