Android SDK sample + "gradle build" error: org.gradle.api.tasks.TaskExecutionException: Execution failed for task

Question

Building the Android SDK sample (android-19/ui/CustomChoiceList) using "gradle build --stacktrace" command:

:CustomChoiceListSample:compileLint
:CustomChoiceListSample:lint
Ran lint on variant debug: 13 issues found
Ran lint on variant release: 13 issues found
Wrote HTML report to file:/sda3/android-sdk-linux/samples/android-19/ui/CustomChoiceList/CustomChoiceListSample/build/lint-results.html
Wrote XML report to /sda3/android-sdk-linux/samples/android-19/ui/CustomChoiceList/CustomChoiceListSample/build/lint-results.xml
:CustomChoiceListSample:lint FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':CustomChoiceListSample:lint'.
> Lint found errors in the project; aborting build.

  Fix the issues identified by lint, or add the following to your build script to proceed with errors:
  ...
  android {
      lintOptions {
          abortOnError false
      }
  }
  ...

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':CustomChoiceListSample:lint'.

BUILD FAILED

Total time: 12.772 secs

Can someone elaborate on the cause of the error?

Answer 1

Fix the errors reported here:

Wrote HTML report to file:/sda3/android-sdk-linux/samples/android-19/ui/CustomChoiceList/CustomChoiceListSample/build/lint-results.html
Wrote XML report to /sda3/android-sdk-linux/samples/android-19/ui/CustomChoiceList/CustomChoiceListSample/build/lint-results.xml

or prevent gradle from stopping when lint detects errors:

android {
    // ...
    // your stuff
    // ...
    lintOptions {
        abortOnError false
     }
}

Answer 2

Gradle now automatically aborts the build if it detects Lint problems. Lint is a utility to analyze the code for possible problems - things that you might see as warnings, not compile errors.

Just add the following to your "build.gradle" file and Lint problems should no longer stop the build.

 android {
      lintOptions {
          abortOnError false
      }
  }
