Android Gradle 插件- 问题 #181142252：从 AS Arctic Fox Canary 7 升级到 Canary 8 时，Gradle 同步启动了 10 次
Created issue. See the attached screenshots. I had to cancel each of them via the cross in the "background tasks" window that appears when you click on the bottom "gutter", then I could perform a Gradle sync again (I did that latter step after changing the AGP version to 7.0.0-alpha08). How can this happen?

- 问题 #195968520：脱糖和可重复构建
Created issue. It seems that when enabling the coreLibraryDesugaring option, the resulting apk output varies wildly from build to build. One set of such differing apks with the resulting diffoscope html diff output can be found in this diffoscope issue: https://salsa.debian.org/reproducible-builds/diffoscope/-/issues/272 STEPS TO REPRODUCE: enable coreLibraryDesugaring (i.e. use this app: https://codeberg.org/corona-contact-tracing-germany/cwa-android/src/branch/debug_reproducible_builds) Build the app twice with ./gradlew clean assembleRelease, saving the resulting apk outputs compare the resulting apks with diff/diffoscope/vbindiff and be quite surprised with the volume of differences Studio Build: - (not studio related) Version of Gradle Plugin: 7.0.0 Version of Gradle: 7.0.2 Version of Java: openjdk-11 OS: Archlinux
- 问题 #195318431：如果使用 tasks.whenTaskAdded 闭包，Android Gradle 插件 7.0.0 不会在 APK 中包含 jniLibs
Created issue. Studio Build: 203.7717.56.2031.7583922 Version of Gradle Plugin: 7.0.0 Version of Gradle: 7.1.1 Version of Java: 11.0.12+7 (Zulu) OS: Ubuntu-20.04 STEPS TO REPRODUCE: 0. Create sample app with NDK. 1. Build the app and find JNI libraries in APK. 2. Add `tasks.whenTaskAdded { }` closure to app/build.gradle. 3. Yearn for the JNI libraries, which are now gone from APK. Hello, My attempt to upgrade a project from AGP-4.2.2 to 7.0.0 was not successful, because the new AGP skips JNI libraries if `tasks.whenTaskAdded { }` closure is present in app/build.gradle. Tried to reproduce the issue on different AGP versions. AGP-4.2.2 is OK. AGP-7.0.0, 7.0.0-rc01, 7.0.0-beta*, 7.0.0-alpha* and 7.1.0-alpha* are all affected. Issue can be reproduced using "app with NDK" template created by Android Studio Arctic Fox 2020.3.1. Uploaded code to https://github.com/ViliusSutkus89/AGP_TasksWhenAdded to better illustrate the issue. Project has Gradle upgraded from default 7.0 to 7.1.1 for AGP-7.1.0-alpha support. Set up a test matrix based on AGP version - https://github.com/ViliusSutkus89/AGP_TasksWhenAdded/actions/runs/1092255141 , which builds the app and checks if the libraries are present in APK.
- 问题 #197146610：“lint check for lint checks”未运行
Created issue. DESCRIBE THE ISSUE IN DETAIL: In the lint-dev Google group, Tor announced "Lint checks for lint checks" here: https://groups.google.com/g/lint-dev/c/q_TVEe85dgc At some point between that announcement and AGP 7.0.0, something seems to have broken that prevents those checks from running. STEPS TO REPRODUCE: Check out the sample custom lint rule project here: https://github.com/googlesamples/android-custom-lint-rules Modify SampleCodeDetector.kt to change an issue id to contain spaces, e.g. id = "Short Unique Id", Run ./gradlew :checks:lint and observe no warnings or errors are reported. Expected: A warning or error should be reported by the built-in LintDetectorDetector.kt check From stepping through with the debugger, my hypothesis is that Lint is incorrectly categorizing the module as an Android module, and these "lint checks for lint checks" are configured to run only on "JDK" module types, not Android modules. More specifically, it seems LintRequest#setPlatform is never called, and the default behavior in this case is to assume an Android module (my knowledge of lint internals gets very fuzzy at this point though). This is an especially bad failure mode because it results in lint passing despite the checks never actually running.
