Run lint when building android studio projects

Question

I would like to be able to run the lint task when I\'m building projects with the android studio to ensure the lint rules are being followed.

I have tried using task

Answer 1

If you want to force Android Studio project to run the lint check before the default run configuration without affecting how your gradle tasks are configured, AND you want to do this in the gradle build system, then you can add the following block outside of the android block in the app module's build.gradle as follows:

android {
....
    lintOptions {
        abortOnError true
    }
}

tasks.whenTaskAdded { task ->
    if (task.name == 'compileDevDebugSources') {
        task.dependsOn lint
        task.mustRunAfter lint
    }
}

Replace compileDevDebugSources with the desired build variant that you have already defined, eg. compileReleaseSources, compileDebugSources, compileStagingDebugSources, etc.

This was tested working on Android Studio 3.0

If you just want to configure your Android Studio project to run the lint check before the default run configuration without affecting how your gradle tasks are configured, you can follow these steps.

1. Open the run configurations drop down and choose edit

2. Select your app run configuration

3. Press the '+' to add a new step

4. Choose "Gradle-aware Make"

5. Type 'check' and choose the option with your app module name and check. (Mine is :app:check)

6. Press the up arrow to move the new check step before the existing Gradle-aware make step

Now, Android Studio will run the lint check and fail the build if any lint errors occur.

here is my solution which also works when you click Build - Make Project in Android Studio:

android {
..
    afterEvaluate {
        applicationVariants.all {
            variant ->
                // variantName: e.g. Debug, Release
                def variantName = variant.name.capitalize()
                // now we tell gradle to always start lint after compile
                // e.g. start lintDebug after compileDebugSources
                project.tasks["compile${variantName}Sources"].doLast {
                    project.tasks["lint${variantName}"].execute()
                }
        }
    }
}

Answer 4

To runt lint and analyze your project, simply select Analyze > Inspect Code.

You should get a nice window with all issues.

Also check Run lint in Android Studio for more information.

I did a little more research, try adding this to your build.gradle.

lintOptions {
      abortOnError true
  } 

There are many options that you can apply to the build.gradle

Just modifying answer of @Yoel Gluschnaider

For me if I use Val it shows error like this : Could not set unknown property 'lintTask' for object of type com.android.build.gradle.internal.api.ApplicationVariantImpl.

So I replace it

applicationVariants.all {
    def lintTask = tasks["lint${name.capitalize()}"]
    assembleProvider.get().dependsOn.add(lintTask)
}

and it work fine!!

Answer 6

just run the "check" task

./gradlew clean check assembleRelease
