I cannot build a simple metric from a java application using the Stackdriver Monitoring client when I have a dependency to the Google Dataflow client.
I get the exception:

}
only when I add:
compile 'com.google.cloud.dataflow:google-cloud-dataflow-java-sdk-all:2.5.0'
as in my gradle file as a dependency.
plugins {
id 'java'
}
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.cloud:google-cloud-monitoring:1.48.0'
// exception with the dependency below
compile 'com.google.cloud.dataflow:google-cloud-dataflow-java-sdk-all:2.5.0'
}
I reported the issue to Google. In the meantime, is there a workaround?
isAndroid
was defined in io.grpc.ManagedChannelProvider taken out of grpc-core in version 1.11. The error means somehow you are using grpc-okhttp from before 1.11 and grpc-core from 1.11 or later.
google-cloud-monitoring 1.48.0 depends indirectly on grpc-core 1.13:

google-cloud-dataflow-java-sdk-all 2.5.0 depends indirectly on grpc-core 1.2 and grpc-okhttp 1.2:

So basically dataflow is out of date and causing a conflict. The dataflow SDK isn't supported anymore, as it is now Apache Beam. Consider migrating to solve the issue.
