Lint

Added in 7.0.0

interface Lint

DSL object for configuring lint options. Example:

android {
   lint {
         // 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
         // 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
         // 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
         checkOnly += ['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

         // if true, generate an HTML report (with issue explanations, sourcecode, etc)
         htmlReport true
         // optional path to HTML report (default will be lint-results.html in the builddir)
         htmlOutput file("$buildDir/reports/lint-report.html")
         // if true, generate a SARIF report (OASIS Static Analysis Results Interchange Format)
         sarifReport true
         // optional path to SARIF report (default will be lint-results.sarif in the builddir)
         sarifOutput file("$buildDir/reports/lint-report.html")
         // 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', 'InlinedApi'
         // Set the severity of the given issues to error
         error 'Wakelock', 'TextViewEdits'

         warning 'ResourceAsColor'
         // Set the severity of the given issues to ignore (same as disabling the check)
         ignore 'TypographyQuotes'
         // Set the severity of the given issues to informational
         informational 'StopShip'
         // Use (or create) a baseline file for issues that should not be reported
         baseline file("lint-baseline.xml")
         // Normally most lint checks are not run on test sources (except the checks
         // dedicated to looking for mistakes in unit or instrumentation tests, unless
         // ignoreTestSources is true). You can turn on normal lint checking in all
         // sources with the following flag, false by default:
         checkTestSources true
         // Like checkTestSources, but always skips analyzing tests -- meaning that it
         // also ignores checks that have explicitly asked to look at test sources, such
         // as the unused resource check.
         ignoreTestSources true
         // Normally lint will skip generated sources, but you can turn it on with this flag
         checkGeneratedSources true
         // Whether lint should check all dependencies too as part of its analysis.
         // Default is false.
         checkDependencies true
         // targetSdk version used when generating a lint report for a library.
         // Must be equal or higher than main target SDK. Must be set for libraries only.

Public properties

abortOnError

Added in 7.1.0

var abortOnError: Boolean

Whether lint should set the exit code of the process if errors are found

absolutePaths

Added in 7.1.0

var absolutePaths: Boolean

Whether lint should display full paths in the error output. By default the paths are relative to the path lint was invoked from.

baseline

Added in 7.1.0

var baseline: File?

The baseline file to use, if any. The baseline file is an XML report previously created by lint, and any warnings and errors listed in that report will be ignored from analysis.

If you have a project with a large number of existing warnings, this lets you set a baseline and only see newly introduced warnings until you get a chance to go back and address the "technical debt" of the earlier warnings.

checkAllWarnings

Added in 7.1.0

var checkAllWarnings: Boolean

Whether lint should check all warnings, including those off by default

checkDependencies

Added in 7.1.0

var checkDependencies: Boolean

Whether lint should check all dependencies too as part of its analysis. Default is false.

checkGeneratedSources

Added in 7.1.0

var checkGeneratedSources: Boolean

Returns whether lint should run checks on generated sources.

checkOnly

Added in 7.0.0

val checkOnly: MutableSet<String>

The exact set of issues to check set by checkOnly.

If empty, lint will detect the issues that are enabled by default plus any issues enabled via enable and without issues disabled via disable.

checkReleaseBuilds

Added in 7.1.0

var checkReleaseBuilds: Boolean

Whether lint should check for fatal errors during release builds. Default is true. If issues with severity "fatal" are found, the release build is aborted.

checkTestSources

Added in 7.1.0

var checkTestSources: Boolean

Whether lint should run all checks on test sources, instead of just the lint checks that have been specifically written to include tests (e.g. checks looking for specific test errors, or checks that need to consider testing code such as the unused resource detector)

disable

Added in 7.0.0

val disable: MutableSet<String>

The set of issue IDs to suppress. Callers are allowed to modify this collection.

enable

Added in 7.0.0

val enable: MutableSet<String>

The set of issue IDs to enable. Callers are allowed to modify this collection.

error

Added in 7.1.0

val error: MutableSet<String>

Issues that have severity overridden to 'error'

explainIssues

Added in 7.1.0

var explainIssues: Boolean

Whether lint should include explanations for issue errors. (Note that HTML and XML reports intentionally do this unconditionally, ignoring this setting.)

fatal

Added in 7.1.0

val fatal: MutableSet<String>

Issues that have severity overridden to 'fatal'

htmlOutput

Added in 7.0.0

var htmlOutput: File?

The optional path to where an HTML report should be written. Setting this property will also turn on htmlReport.

htmlReport

Added in 7.0.0

var htmlReport: Boolean

Whether we should write an HTML report. Default is true. The location can be controlled by htmlOutput.

ignore

Added in 7.1.0

Deprecated in 7.1.0

val ignore: MutableSet<String>

Issues that have severity overridden to 'ignore'

ignoreTestFixturesSources

Added in 7.2.0

var ignoreTestFixturesSources: Boolean

Whether lint should ignore all testFixtures sources.

ignoreTestSources

Added in 7.1.0

var ignoreTestSources: Boolean

Whether lint should ignore all test sources. This is like checkTestSources, but always skips analyzing tests -- meaning that it also ignores checks that have explicitly asked to look at test sources, such as the unused resource check.

ignoreWarnings

Added in 7.1.0

var ignoreWarnings: Boolean

Returns whether lint will only check for errors (ignoring warnings)

informational

Added in 7.1.0

val informational: MutableSet<String>

Issues that have severity overridden to 'informational'

lintConfig

Added in 7.0.0

var lintConfig: File?

The default config file to use as a fallback. This corresponds to a lint.xml file with severities etc to use when a project does not have more specific information.

noLines

Added in 7.1.0

var noLines: Boolean

Whether lint should include the source lines in the output where errors occurred (true by default)

quiet

Added in 7.1.0

var quiet: Boolean

Whether lint should be quiet (for example, not write informational messages such as paths to report files written)

sarifOutput

Added in 7.0.0

var sarifOutput: File?

The optional path to where a SARIF report (OASIS Static Analysis Results Interchange Format) should be written. Setting this property will also turn on sarifReport.

sarifReport

Added in 7.0.0

var sarifReport: Boolean

Whether we should write a SARIF (OASIS Static Analysis Results Interchange Format) report. Default is false. The location can be controlled by sarifOutput.

showAll

Added in 7.1.0

var showAll: Boolean

Whether lint should include all output (e.g. include all alternate locations, not truncating long messages, etc.)

targetSdk

Added in 8.2.0

var targetSdk: Int?

The target sdk version used when generating a lint report for a library. Must be equal or higher than main target SDK. Must be set for libraries only.

targetSdkPreview

Added in 8.2.0

var targetSdkPreview: String?

The target sdk preview version used when generating a lint report for a library. Must be set for libraries only.

textOutput

Added in 7.0.0

var textOutput: File?

The optional path to where a text report should be written.

To output the lint report to stdout set textReport=true, and leave textOutput unset.

textReport

Added in 7.0.0

var textReport: Boolean

Whether lint should write a text report.

With the default setting (textReport=false), the lint task will print a summary to stdout if there are any lint warnings or errors including a link to the full text report.

When textReport=true and textOutput is unset, the full report will be printed by the lint task, rather than just a summary. When textOutput is set, the full text report will be copied to the specified location.
