如何判断何时从AndroidStudio运行gradle？

Question

I need to build some hacks into my gradle build file so that Android Studio understands some things. I don't need these hacks when I run the build from the command line directory. Is there a way to detect when the build is being run from within Android Studio? Maybe through environment variables, etc?

Answer 1

With AndroidStudio 2.1.1 , you can use the idea.platform.prefix property:

def sysprops = System.getProperties()
if (sysprops['idea.platform.prefix'] != null) {
    // Built from AndroidStudio
} else {
    // Built from command line
}

Answer 2

Use gradle -P blah=val from command line and in your build.gradle use project.hasProperty("blah") or project.getProperty("test") or if (blah ... ) to decide whether run your hack or not.

Updated:

OK I found the direct way :)

def env = System.getProperties()
if (env['com.android.studio.gradle.project.path'] != null) {
    // build from Android Studio, do magic here
}

Jake Wharton suggests android.injected.invoked.from.ide to speed butterknife at development time by using reflection :

dependencies {
  if (properties.containsKey('android.injected.invoked.from.ide')) {
    implementation 'com.jakewharton:butterknife-reflect:<version>'
  } else {
    implementation 'com.jakewharton:butterknife:<version>'
    kapt 'com.jakewharton:butterknife-compiler:<version>'
  }
}

From Twitter :

Hey ButterKnife users: I'm working on a reflection-based implementation for use during development so the annotation processor is not needed.

A follow-up :

What is this? A property from (link: http://gradle.properties ) gradle.properties?

The answer we want :

No it's added by the IDE
