从 Android Studio 的构建中排除 class

Question

I've been learning Android over the past few months and have been using Eclipse v4.2 (Juno) as my IDE.

I am trying to migrate to Android Studio. How can I exclude some of the classes from build path I have yet to complete?

In Eclipse, it was a straightforward right click. I can't find any reference to it in Android Studio.

Answer 1

AFAIK IntelliJ allows to exclude packages. Open Project Structure (Ctr+Alt+Shift+S in Linux) > Modules > Sources Tab.

However if you would like to exclude only one class use Gradle build file.

Android Studio uses Gradle so in build.gradle file add inside android configuration custom SourceSet that excludes your class eg:

android {
  compileSdkVersion 19
  buildToolsVersion "19.0.3"

  defaultConfig {
     minSdkVersion 19
     targetSdkVersion 19
     packageName "org.homelab.lab"
     testPackageName "org.homelab.lab.test"

  }
  sourceSets {
     main {
         java {
             exclude '**/SomeExcludedClass.java'
         }
     }
     androidTest {
         java {
             exclude '**/TestSomeExcludedClass.java'
        }
     }
  }
 }

Answer 2

It can't be done.

Maybe it could back in May'13 when the accepted answer was provided, but not anymore (as of 1.2).

Here is the issue:

According to the labels they are targetting AS 1.5 for adding these feature.

Works fine with Android Studio v3.0

apply plugin: 'com.android.application'

android {
    defaultConfig {...}
    buildTypes {...}
    sourceSets {
        main {
            java {
                exclude 'com/example/full/package/path/MainActivity.java'
            }
        }
    }
}

Answer 4

Move it to a new folder. Rightclick -> Show in explorer -> cut then paste to a new folder (outside of any project). I just create a new folder inside of AndroidStudioProjects folder and placed them there.

Answer 5

The way I used to do the same is by,

For Windows :Right click on the java file -> Show in Explorer -> change extension of file from '.java' to '.c'

For Mac :Right click on the java file -> Reveal in Finder -> change extension of file from '.java' to '.c'

As simple as that.

Answer 6

Cross posting from https://stackoverflow.com/a/69261642/3689782 but it seems useful to repeat here.

I came across a way to make this work specifically for Android unit tests (but I'm assuming it's adaptable) using a combination of other solutions from the link above:

def filesToExclude = [
    '**/*TestOne*.kt',
    '**/*TestTwo*.kt',
    ...
]
tasks.withType(org.gradle.api.tasks.SourceTask.class).configureEach {
  it.exclude(filesToExclude)
}
android.sourceSets.test.kotlin.exclude(filesToExclude)

In my particular case, the extra wildcards around the test name were needed due to other generation occurring (specifically, Dagger with kapt).

This seems to be a bit hacky way to approach it, but it works by ensuring the test target is excluded from all tasks that it could actually be excluded from (including both build & kapt tasks). The sourceSets exclusion is still necessary for the file not to be picked up for compilation (I think this is the Kotlin Gradle Plugin doing it, but it might also be Android Gradle Plugin--I'm not well versed enough in debugging Gradle builds to pin it down).

Answer 7

For my case I need to prevent a whole folder then I did it by this -

    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
            java {
                exclude 'com/example/myfolder'
 /* The holder name I want to excludes its all classes */
            }
        }
    }
