Getting the following errors after applying proguard rules:
Could not find method create() for arguments [crashlyticsStoreDeobsRelease, class com.crashlytics.tools.gradle.tasks.StoreMappingFileTask, com.android.build.gradle.internal.scope.BuildArtifactsHolder$FinalBuildableArtifact@1711854a] on task set of type org.gradle.api.internal.tasks.DefaultTaskContainer.
It looks like the version of fabric build tools in your build.gradle is set to something like classpath 'io.fabric.tools:gradle:+'
which means it always uses the newest available version.
The current version 1.26.0 seems broken so you can temporarily set exact version to 1.25.4: classpath 'io.fabric.tools:gradle:1.25.4'
.
Checked a couple of minutes ago, it works.
UPD: new version io.fabric.tools(1.26.1) is released. classpath 'io.fabric.tools:gradle:+'
now works well
