(#) Gradle Implicit Getter Call !!! ERROR: Gradle Implicit Getter Call This is an error. Id : `GradleGetter` Summary : Gradle Implicit Getter Call Severity : Error Category : Correctness Platform : Android Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : Initial Affects : Gradle build 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 Gradle will let you replace specific constants in your build scripts with method calls, so you can for example dynamically compute a version string based on your current version control revision number, rather than hardcoding a number. When computing a version name, it's tempting to for example call the method to do that `getVersionName`. However, when you put that method call inside the `defaultConfig` block, you will actually be calling the Groovy getter for the `versionName` property instead. Therefore, you need to name your method something which does not conflict with the existing implicit getters. Consider using `compute` as a prefix instead of `get`. (##) Example Here is an example of lint warnings produced by this check: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text build.gradle:18:Error: Bad method name: pick a unique method name which does not conflict with the implicit getters for the defaultConfig properties. For example, try using the prefix compute- instead of get-. [GradleGetter] versionCode getVersionCode -------------------------- build.gradle:19:Error: Bad method name: pick a unique method name which does not conflict with the implicit getters for the defaultConfig properties. For example, try using the prefix compute- instead of get-. [GradleGetter] versionName getVersionName -------------------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here is the source file referenced above: `build.gradle`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~groovy linenumbers apply plugin: 'com.android.application' def getVersionName() { "1.0" } def getVersionCode() { 50 } android { compileSdkVersion 19 buildToolsVersion "19.0.0" defaultConfig { minSdkVersion 7 targetSdkVersion 17 versionCode getVersionCode versionName getVersionName } } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can also visit the [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) 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.testSetter`.

(##) Suppressing You can suppress false positives using one of the following mechanisms: * Using a suppression comment like this on the line above: ```kt //noinspection GradleGetter 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="GradleGetter" 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 'GradleGetter' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore GradleGetter ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
