gradle build fails on lint task

With 0.7.0 there comes extended support for Lint, however, it does not work always properly. (Eg. the butterknife library)

Solution is to disable aborting build on found lint errors

I took the inspiration from
https://android.googlesource.com/platform/tools/base/+/e6a5b9c7c1bca4da402de442315b5ff1ada819c7

(implementation:
https://android.googlesource.com/platform/tools/base/+/e6a5b9c7c1bca4da402de442315b5ff1ada819c7/build-system/gradle/src/main/groovy/com/android/build/gradle/internal/model/DefaultAndroidProject.java )

(discussion: https://plus.google.com/+AndroidDevelopers/posts/ersS6fMLxw1 )

android {
  // your build config
  defaultConfig { ... }
  signingConfigs { ... }
  compileOptions { ... }
  buildTypes { ... }
  // This is important, it will run lint checks but won't abort build
  lintOptions {
      abortOnError false
  }
}

And if you need to disable just particular Lint rule and keep the build failing on others, use this:

/*
 * Use only 'disable' or only 'enable', those configurations exclude each other
 */
android {
  lintOptions {
    // use this line to check all rules except those listed
    disable 'RuleToDisable', 'SecondRuleToDisable'
    // use this line to check just listed rules
    enable 'FirstRuleToCheck', 'LastRuleToCheck'
  }
}
