Bug persists: Release build fails with dynamic install-time module on Flutter 3.35.0+ (compileOnly dependency issue) #177037
Description
Steps to reproduce
This issue is still reproducible on Flutter 3.35.0+, even though the original report (#175713) was closed.
The problem described there has not been resolved — the release build continues to fail when using a dynamic install-time module that includes compileOnly dependencies.
After further investigation, I found that this issue originates from the FlutterPlugin.kt file, which is part of Flutter’s own referenced source code, specifically in the following code snippet:
rootProject.allprojects {
repositories.maven {
url = uri(repository!!)
}
if (plugins.hasPlugin("com.android.application") && isInvokedFromAndroidStudio()) {
dependencies.add("compileOnly", "io.flutter:flutter_embedding_debug:$engineVersion")
dependencies.add("compileOnly", "io.flutter:armeabi_v7a_debug:$engineVersion")
dependencies.add("compileOnly", "io.flutter:arm64_v8a_debug:$engineVersion")
dependencies.add("compileOnly", "io.flutter:x86_64_debug:$engineVersion")
}
}
I temporarily modified the code as follows, and the build succeeded:
rootProject.allprojects {
repositories.maven {
url = uri(repository!!)
}
if (plugins.hasPlugin("com.android.application") && isInvokedFromAndroidStudio()) {
dependencies.add("debugImplementation", "io.flutter:flutter_embedding_debug:$engineVersion")
dependencies.add("debugImplementation", "io.flutter:armeabi_v7a_debug:$engineVersion")
dependencies.add("debugImplementation", "io.flutter:arm64_v8a_debug:$engineVersion")
dependencies.add("debugImplementation", "io.flutter:x86_64_debug:$engineVersion")
}
}
This is the FlutterPlugin.kt file from version 3.32.6, and it does not contain the line in question.
Please take a look at my analysis and detailed description above for further context.
val hostedRepository: String =
System.getenv(FlutterPluginConstants.FLUTTER_STORAGE_BASE_URL)
?: FlutterPluginConstants.DEFAULT_MAVEN_HOST
val repository: String? =
if (FlutterPluginUtils.shouldProjectUseLocalEngine(project)) {
project.property(PROP_LOCAL_ENGINE_REPO) as String?
} else {
"$hostedRepository/${engineRealm}download.flutter.io"
}
rootProject.allprojects {
repositories.maven {
url = uri(repository!!)
}
}
project.apply {
from(
Paths.get(
flutterRoot!!.absolutePath,
"packages",
"flutter_tools",
"gradle",
"src",
"main",
"scripts",
"native_plugin_loader.gradle.kts"
)
)
}
Expected results
The project should build successfully in release mode without any errors, as it functions with Flutter versions 3.32.6 and below.
Actual results
The release build process fails with the following error:
The following Android dependencies are set to compileOnly which is not supported:
-> io.flutter:arm64_v8a_debug:1.0.0-c29809135135e262a912cf583b2c90deb9ded610
