…Gradle build: proxy classes, manifest rewrite, quickbuild.json Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Kj9YeCDHGp9DU8LPtfWJ7W
…ection, min-AGP guard
Review finding 1 (renamed services/receivers silently break explicit intents) → services and
receivers now keep their real manifest names, per the design doc's own no-proxy path: the
appComponentFactory instantiates the manifest name through the payload loader (like the
Application), Android has no service/receiver alias to compensate a rename with, and neither
kind uses the activity-only getClassLoader injection. They stay recorded in setup.json (null
proxyClass) so the restart rule still sees them; resolver-skipped library components stay out,
as before. Covered by QuickBuildManifestTransformerTest ("services keep their real manifest
names so explicit start-service intents still resolve", "receivers keep their real name...",
"project-owned services stay recorded...", plus the rewritten skip/numbering tests). Docs
updated in step (component-proxying-design.md, quickbuild/README.md, ComponentInfo.kt,
live-reload-alternatives.md).
Review finding 3 (fail-quiet runtime-AAR injection) → the injection path now goes through
QuickBuildPlugin.requireRuntimeConfiguration, which throws a GradleException naming the
variant and the unrecognized AGP variant type instead of silently producing a proxy APK that
crashes at launch; the .flat-overlay caller keeps its documented graceful degrade. Covered by
QuickBuildPluginTest ("requireRuntimeConfiguration fails the build loudly on an unrecognized
variant type", "runtimeConfigurationOrNull degrades to null for the resources overlay path").
Review finding 2 (deleted min-AGP guard) → restored as a minAgpCheck source set wired into
`check`: it recompiles every non-Quick-Build plugin source against AGP_VERSION_MINIMUM, so an
AGP-8-only API in LogSenderPlugin/AndroidIDEGradlePlugin goes red again. Quick Build sources
are excluded (they genuinely need the newer AGP and load only when enabled); to keep that
exclusion compilable, AndroidIDEGradlePlugin applies QuickBuildPlugin by name, pinned to the
real class by QuickBuildPluginTest ("the reflective quick build plugin name resolves to the
real class"). The guard task itself is the red light for build-file regressions. This restore
is the conservative option; dropping the guard again can be re-proposed separately with
rationale if the team prefers compile-against-latest only.

📝 Walkthrough
WalkthroughThe Gradle plugin now conditionally activates Quick Build, supports multiple AGP versions, transforms manifests, generates proxy sources and payload dex files, writes variant setup metadata, and validates these paths with unit and functional tests. ChangesQuick Build Gradle integration
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds Quick Build proxy-app provisioning, but the current head can omit the runtime AAR and fail at launch, while its test fixture permits public repository access by default and its test setup breaks on Windows path formats.

ASM 9.7.1 ClassReader supported class file major versions and Unsupported class file major version behavior
💡 Result:
ASM 9.7.1 is designed to support class files up to and including Java 24 (class file major version 68) [1][2][3]. Regarding the behavior when encountering an unsupported class file major version: When the ClassReader encounters a class file with a major version higher than what it is explicitly programmed to support, it throws an IllegalArgumentException [4][5][6]. The constructor checks the major_version field (located at offset 6 in the class file structure) against a hardcoded constant (e.g., Opcodes.V24 in ASM 9.7.1) when the checkClassVersion parameter is set to true [7][1]. It is important to note that ASM developers specifically recommend that users perform their own checks on the class file version bytes (offset 6) if they wish to provide custom or more specific error handling (such as throwing UnsupportedClassVersionError), rather than relying on the internal exception thrown by the ClassReader [8]. This is because the ASM library may be updated to support new versions, but the visitor implementations or processing logic downstream may not be [8]. Some downstream projects (like the Spring Framework) patch their internal copies of ASM to be more lenient when encountering newer class file versions to avoid these exceptions [9].

The error IllegalArgumentException: unsupported class file version, when encountered while using the ASM library, typically indicates that the ASM version you are using is too old to parse the bytecode version of the Java class file you are attempting to process [1][2]. The ASM library relies on constant values (defined in the Opcodes interface) to identify and handle specific Java class file versions (e.g., V24, V23) [1][3]. If a class file was compiled with a newer version of the Java compiler than the ASM library was designed to support, the ClassReader will be unable to recognize the version and will throw an exception [1][4]. To resolve this issue: 1. Update your ASM dependency: Ensure you are using the most recent version of the ASM library available [2]. ASM is frequently updated to support new Java class file versions as they are released [1]. As of August 2026, ASM version 9.10.1 or later is recommended [2]. 2. Check your compiler settings: If you cannot update ASM, ensure that the Java classes you are processing are compiled with a target version compatible with your current version of ASM [4]. For example, if you are using ASM 9.7.1, you should ensure the code is compiled for a Java version supported by that release [1]. You can verify the supported versions by checking the Opcodes interface or the release notes for your specific version of ASM [1][3].

Handle unparsable class bytes in resolve.
ClassReader can throw for truncated bytes and for class files newer than ASM 9.7.1 supports (Java 23, major version 67). Treat parser failures as undecidable and return Resolution.Proxiable instead of failing the Quick Build task.

Gradle Project.fileTree with a single file as baseDir - does it resolve to an empty file tree?
💡 Result:
No, providing a single file as the baseDir to Gradle's Project.fileTree does not automatically resolve to an empty file tree, but its behavior depends on whether the specified path points to a file or a directory. A FileTree in Gradle is fundamentally designed to represent a hierarchy of files rooted at a specific base directory [1][2]. When you call Project.fileTree(Object baseDir), Gradle treats the baseDir as the root of that tree [1][3]. If the path provided to baseDir points to a file rather than a directory, Gradle will still attempt to treat it as the base. Since a FileTree scans the contents of its base directory (excluding the base directory itself) [1][3], attempting to use a regular file as a base directory will typically result in an empty file collection because a regular file does not contain a directory structure for Gradle to scan. If you need to include a specific file as a FileTree, you should instead point the baseDir to the parent directory of that file and use include patterns to select only the target file [1][3]. For example: // Correct way to include a single file in a FileTree def tree = fileTree(dir: 'path/to/parent') { include 'target-file.txt' } This approach ensures the FileTree correctly identifies and contains the file you intend to use [1][3].

Gradle 8.14.4 Project.fileTree(File) regular file FileTree root behavior and DependencyHandler.create(FileTree) file dependency semantics
💡 Result:
In Gradle, the behavior and semantics of file-based operations are defined as follows: Project.fileTree(File) Behavior The Project.fileTree(baseDir) method creates a ConfigurableFileTree that represents a hierarchy of files within the specified base directory [1][2]. Key characteristics include: - Root Exclusion: The method creates a tree of all files and directories contained within the base directory, but it does not include the base directory itself as a member of the tree [2]. - Lazy and Live Evaluation: The returned FileTree is lazy, meaning it scans for files only when its contents are queried [1][3]. It is also live, so it re-scans for files each time the contents are accessed [1][3]. - Task Output Caveat: When a FileTree is used directly as a task output (e.g., via filtering), Gradle may consider the root directory itself as the output, which can cause task dependency and validation issues [4]. A common workaround is to use the.elements property of the FileTree to target the specific files/directories instead of the tree root [4]. DependencyHandler.create(FileTree) Semantics The DependencyHandler is primarily used to declare dependencies on files or directories [5][6]. - File Dependencies: Passing a FileTree (or FileCollection) to a dependency configuration (e.g., implementation(fileTree("libs"))) adds all files found within that tree to the classpath [5][6]. - Semantics: When you pass a FileTree to a configuration, it is treated as a file-based dependency (represented as a FileCollectionDependency) [5][6]. Unlike module dependencies (group:name:version), these do not have metadata and are resolved directly from the filesystem [5][7]. - Implicit Resolution: Because FileTree is "live," using it as a dependency ensures that files added to or removed from the directory after the dependency is declared will be reflected when the configuration is resolved during the build [2][5]. Top results: [2][4][5][6]

Use project.files(runtimeAar) for the runtime dependency. runtimeAar is a regular file, but project.fileTree(runtimeAar) scans it as a directory root and contributes no AAR entry. The runtime classpath can therefore omit APP_COMPONENT_FACTORY, causing ClassNotFoundException at launch.

Keep the functional fixture off-device by default.
These repositories let the fixture contact Google Maven, Maven Central, and the Gradle Plugin Portal. The real assemble path has no opt-in, warning, or cancellation path. Stage the required AGP and AndroidX artifacts in the local test repositories, then remove the public repositories from this fixture.
As per coding guidelines, "Avoid http or https links which go off-device. When such links are unavoidable, warn the user beforehand and offer to cancel the action."
