| /** |
| * In AGP 4.0, the Android linter task depends on the JAR tasks that generate `libapp.so`. |
| * When building APKs, this causes an issue where building release requires the debug JAR, |
| * but Gradle won't build debug. |
| * |
| * To workaround this issue, only configure the JAR task that is required given the task |
| * from the command line. |
| * |
| * The AGP team said that this issue is fixed in Gradle 7.0, which isn't released at the |
| * time of adding this code. Once released, this can be removed. However, after updating to |
| * AGP/Gradle 7.2.0/7.5, removing this hack still causes build failures. Futher |
| * investigation necessary to remove this. |
| * |
| * Tested cases: |
| * * `./gradlew assembleRelease` |
| * * `./gradlew app:assembleRelease.` |
| * * `./gradlew assemble{flavorName}Release` |
| * * `./gradlew app:assemble{flavorName}Release` |
| * * `./gradlew assemble.` |
| * * `./gradlew app:assemble.` |
| * * `./gradlew bundle.` |
