ARouter::Register >>> LogisticsCenter.class was not found…

Error message

ARouter::Register >>> LogisticsCenter.class was not found; automatic registration was not injected

What it means

Not an exception: ScopedRegisterTask logs this warning when, after scanning transformed classes, result.logisticsCenterFound is false — i.e. ARouter's LogisticsCenter.class was never seen, so automatic route registration could not be injected into it. The build succeeds but the generated routes will not be registered at runtime.

Solutions

1. Add the ARouter api dependency (`implementation 'com.alibaba:arouter-api:x.y.z'`) and ensure the compiler/gradle plugin versions match.
2. Check the task's input configuration includes the jar/dex containing LogisticsCenter.class.
3. Confirm R8/ProGuard keep rules for com.alibaba.android.arouter.launcher.LogisticsCenter so it survives shrinking.

Example fix

// before (build.gradle)
dependencies {
    annotationProcessor 'com.alibaba:arouter-compiler:1.2.2'
}

// after
dependencies {
    implementation 'com.alibaba:arouter-api:1.5.2'
    annotationProcessor 'com.alibaba:arouter-compiler:1.2.2'
}

// verify in build.gradle before building
def hasApi = configurations.implementation.allDependencies.any {
    it.group == 'com.alibaba' && it.name == 'arouter-api'
}
if (!hasApi) {
    logger.warn('arouter-api missing: automatic route registration will be skipped')
}

When it happens

Trigger: The register task scans inputs that do not contain LogisticsCenter.class — e.g. the ARouter core dependency is missing from the variant, jar inputs are excluded, or the class lives in a jar not passed to the transformer/task.

Common situations: Forgetting the arouter-api dependency; shrinking/obfuscation config removing LogisticsCenter; registering only app module classes while LogisticsCenter resides in a library jar not included in the task inputs.
