(#) Obsolete Gradle Dependency !!! WARNING: Obsolete Gradle Dependency This is a warning. Id : `GradleDependency` Summary : Obsolete Gradle Dependency Severity : Warning Category : Correctness Platform : Any Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : Initial Affects : Gradle build files and TOML files Editing : This check runs on the fly in the IDE editor Implementation : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-checks/src/main/java/com/android/tools/lint/checks/GradleDetector.kt) Tests : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/GradleDetectorTest.kt) Copyright Year : 2014 This detector looks for usages of libraries where the version you are using is not the current stable release. Using older versions is fine, and there are cases where you deliberately want to stick with an older version. However, you may simply not be aware that a more recent version is available, and that is what this lint check helps find. !!! Tip This lint check has an associated quickfix available in the IDE. (##) Example Here is an example of lint warnings produced by this check: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text build.gradle:24:Warning: A newer version of com.google.guava:guava than 11.0.2 is available: 17.0 [GradleDependency] freeCompile 'com.google.guava:guava:11.0.2' ------------------------------- build.gradle:25:Warning: A newer version of com.android.support:appcompat-v7 than 13.0.0 is available: 25.3.1 [GradleDependency] compile 'com.android.support:appcompat-v7:13.0.0' ----------------------------------------- build.gradle:26:Warning: A newer version of com.google.android.support:wearable than 1.2.0 is available: 1.3.0 [GradleDependency] compile 'com.google.android.support:wearable:1.2.0' ------------------------------------------- build.gradle:27:Warning: A newer version of com.android.support:multidex than 1.0.0 is available: 1.0.1 [GradleDependency] compile 'com.android.support:multidex:1.0.0' ------------------------------------ build.gradle:29:Warning: A newer version of com.android.support.test:runner than 0.3 is available: 0.5 [GradleDependency] androidTestCompile 'com.android.support.test:runner:0.3' ------------------------------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here is the source file referenced above: `build.gradle`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~groovy linenumbers apply plugin: 'android' android { compileSdkVersion buildToolsVersion "19.0.0" defaultConfig { minSdkVersion 7 targetSdkVersion 17 versionCode 1 versionName "1.0" } productFlavors { free { } pro { } } } dependencies { compile 'com.android.support:appcompat-v7:+' freeCompile 'com.google.guava:guava:11.0.2' compile 'com.android.support:appcompat-v7:13.0.0' compile 'com.google.android.support:wearable:1.2.0' compile 'com.android.support:multidex:1.0.0' androidTestCompile 'com.android.support.test:runner:0.3' } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can also visit the source code ([GradleDetectorTest.kt](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/GradleDetectorTest.kt) [PropertyFileDetectorTest.kt](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/PropertyFileDetectorTest.kt) for the unit tests for this check to see additional scenarios. The above example was automatically extracted from the first unit test found for this lint check, `GradleDetector.testBasic`. To report a problem with this extracted sample, visit https://issuetracker.google.com/issues/new?component=192708. (##) Suppressing You can suppress false positives using one of the following mechanisms: * Using a suppression comment like this on the line above: ```kt //noinspection GradleDependency problematicStatement() ``` * Using a special `lint.xml` file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this: ```xml <?xml version="1.0" encoding="UTF-8"?> <lint> <issue id="GradleDependency" severity="ignore" /> </lint> ``` Instead of `ignore` you can also change the severity here, for example from `error` to `warning`. You can find additional documentation on how to filter issues by path, regular expression and so on [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html). * In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like ```gradle lintOptions { disable 'GradleDependency' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore GradleDependency ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
