gradle build fails on lint task

Solution 1:

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'
  }
}

Solution 2:

if abortOnError false will not resolve your problem, you can try this.

lintOptions {
    checkReleaseBuilds false
}

Solution 3:

You can select proper options from here

android {
    lintOptions {
        // set to true to turn off analysis progress reporting by lint
        quiet true
        // if true, stop the gradle build if errors are found
        abortOnError false
        // if true, only report errors
        ignoreWarnings true
        // if true, emit full/absolute paths to files with errors (true by default)
        //absolutePaths true
        // if true, check all issues, including those that are off by default
        checkAllWarnings true
        // if true, treat all warnings as errors
        warningsAsErrors true
        // turn off checking the given issue id's
        disable 'TypographyFractions','TypographyQuotes'
        // turn on the given issue id's
        enable 'RtlHardcoded','RtlCompat', 'RtlEnabled'
        // check *only* the given issue id's
        check 'NewApi', 'InlinedApi'
        // if true, don't include source code lines in the error output
        noLines true
        // if true, show all locations for an error, do not truncate lists, etc.
        showAll true
        // Fallback lint configuration (default severities, etc.)
        lintConfig file("default-lint.xml")
        // if true, generate a text report of issues (false by default)
        textReport true
        // location to write the output; can be a file or 'stdout'
        textOutput 'stdout'
        // if true, generate an XML report for use by for example Jenkins
        xmlReport false
        // file to write report to (if not specified, defaults to lint-results.xml)
        xmlOutput file("lint-report.xml")
        // if true, generate an HTML report (with issue explanations, sourcecode, etc)
        htmlReport true
        // optional path to report (default will be lint-results.html in the builddir)
        htmlOutput file("lint-report.html")

        // set to true to have all release builds run lint on issues with severity=fatal
        // and abort the build (controlled by abortOnError above) if fatal issues are found
        checkReleaseBuilds true
        // Set the severity of the given issues to fatal (which means they will be
        // checked during release builds (even if the lint target is not included)
        fatal 'NewApi', 'InlineApi'
        // Set the severity of the given issues to error
        error 'Wakelock', 'TextViewEdits'
        // Set the severity of the given issues to warning
        warning 'ResourceAsColor'
        // Set the severity of the given issues to ignore (same as disabling the check)
        ignore 'TypographyQuotes'
    }
}

Solution 4:

I had some lint errors in Android Studio that occurred only when I generated a signed APK.

To avoid it, I added the following to build.gradle

android {
    lintOptions {
        checkReleaseBuilds false
    }
}

Solution 5:

Add these lines to your build.gradle file:

android { 
  lintOptions { 
    abortOnError false 
  }
}

Then clean your project :D
