databinding error in Android Bazel project

[salim-boudriiya]

Hi @jin,

We are working (@gonzaloruizdevilla) on a project, where the use of databinding functionality is needed, but we encounter the following problem:

build did NOT complete successfully (33 packages loaded, 1068 targets configured) Internal error thrown during build. Printing stack trace: java.lang.RuntimeException: Unrecoverable error while evaluating node '//Android/Components/Mobisec-STGAuthenticators-Android/src/main:authenticatorslib BuildConfigurationValue.Key[f3f502b3f0d1aee893a3fe534606da2c] false' (requested by nodes ) at com.google.devtools.build.skyframe.AbstractParallelEvaluator$Evaluate.run(AbstractParallelEvaluator.java:528) at com.google.devtools.build.lib.concurrent.AbstractQueueVisitor$WrappedRunnable.run(AbstractQueueVisitor.java:399) at java.base/java.util.concurrent.ForkJoinTask$AdaptedRunnableAction.exec(Unknown Source) at java.base/java.util.concurrent.ForkJoinTask.doExec(Unknown Source) at java.base/java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(Unknown Source) at java.base/java.util.concurrent.ForkJoinPool.scan(Unknown Source) at java.base/java.util.concurrent.ForkJoinPool.runWorker(Unknown Source) at java.base/java.util.concurrent.ForkJoinWorkerThread.run(Unknown Source) Caused by: java.lang.NullPointerException at com.google.devtools.build.lib.rules.java.JavaCompilationHelper.usesAnnotationProcessing(JavaCompilationHelper.java:433) at com.google.devtools.build.lib.rules.android.AndroidCommon.initJava(AndroidCommon.java:613) at com.google.devtools.build.lib.rules.android.AndroidCommon.init(AndroidCommon.java:547) at com.google.devtools.build.lib.rules.android.AndroidLibrary.create(AndroidLibrary.java:201) at com.google.devtools.build.lib.rules.android.AndroidLibrary.create(AndroidLibrary.java:43) at com.google.devtools.build.lib.analysis.ConfiguredTargetFactory.createRule(ConfiguredTargetFactory.java:331) at com.google.devtools.build.lib.analysis.ConfiguredTargetFactory.createConfiguredTarget(ConfiguredTargetFactory.java:182) at com.google.devtools.build.lib.skyframe.SkyframeBuildView.createConfiguredTarget(SkyframeBuildView.java:767) at com.google.devtools.build.lib.skyframe.ConfiguredTargetFunction.createConfiguredTarget(ConfiguredTargetFunction.java:891) at com.google.devtools.build.lib.skyframe.ConfiguredTargetFunction.compute(ConfiguredTargetFunction.java:351) at com.google.devtools.build.skyframe.AbstractParallelEvaluator$Evaluate.run(AbstractParallelEvaluator.java:451)

Please, could you tell me what the problem is due to.

Are we doing something wrong?

The Build file we use is the following:

############################################# package(default_visibility = ["//visibility:public"]) load("@rules_jvm_external//:defs.bzl", "artifact") load("@rules_android//android:rules.bzl", "android_library")

MANIFEST = "AndroidManifest.xml" PACKAGE = "com.globile.santander.mobisec.authenticators"

android_library( name = "authenticatorslib", manifest = MANIFEST, custom_package = PACKAGE, enable_data_binding = True, resource_files = glob(["res/"]), srcs = glob(["java//*.java"]), deps = [ "//Android/Components/Mobisec-SCAL-Android/src/main:scallib", artifact("androidx.appcompat:appcompat"), artifact("androidx.fragment:fragment"), artifact("androidx.core:core"), artifact("androidx.lifecycle:lifecycle-runtime"), artifact("androidx.lifecycle:lifecycle-viewmodel"), artifact("androidx.lifecycle:lifecycle-common"), artifact("androidx.lifecycle:lifecycle-livedata"), artifact("androidx.lifecycle:lifecycle-extensions"), artifact("androidx.lifecycle:lifecycle-livedata-core"), artifact("androidx.drawerlayout:drawerlayout"), artifact("androidx.annotation:annotation"), artifact("com.crashlytics.sdk.android:crashlytics"), artifact("io.fabric.sdk.android:fabric"), artifact("com.google.code.gson:gson"), artifact("io.reactivex.rxjava2:rxjava"), artifact("io.reactivex.rxjava2:rxandroid"), artifact("org.reactivestreams:reactive-streams"), artifact("com.journeyapps:zxing-android-embedded"), artifact("androidx.savedstate:savedstate"), artifact("com.squareup.okhttp3:okhttp"), artifact("com.squareup.okhttp3:logging-interceptor"), artifact("net.zetetic:android-database-sqlcipher"), artifact("com.google.android.gms:play-services-vision"), artifact("com.squareup.retrofit2:converter-gson"), artifact("com.squareup.retrofit2:retrofit"), artifact("com.squareup.retrofit2:converter-scalars"), artifact("com.android.support:support-annotations"), artifact("com.android.support:design"), artifact("android.arch.lifecycle:extensions"), artifact("com.android.support:cardview-v7"), artifact("com.android.support:appcompat-v7"), artifact("com.android.support.constraint:constraint-layout"), artifact("com.android.databinding:baseLibrary"), artifact("com.android.databinding:adapters"),

afaik databinding does not work with bazel yet.

Hi @ahumesky,

Any progress on the subject of databinding?

We can (@gonzaloruizdevilla) contribute to help you in this development.

It is very important for us to have that functionality.

Best Regards.
