Pub/Sub: Unable to compile Pull client

[NicolaSpreafico]

Following the documentation I added this dependency to my project

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-pubsub</artifactId>
  <version>0.20.0-beta</version>
</dependency>

but looking inside the Maven Central I can see that is not deployed yet.

I then tried the 0.19.0-alpha version, but my Maven project does not compile.
Note that is a brand new Maven Project created with maven-quickstart-archetype, I simply created it and then added the dependency

I don't even started to implement the sample code provided here (https://github.com/GoogleCloudPlatform/google-cloud-java/tree/master/google-cloud-pubsub)

Is the Maven deployed version broke?
When the 0.20.0-beta version (which stage from alpha to beta) will be deployed?
Are there any dependecies that need to be added?

[garrettjonesgoogle]

mvnrepository.com isn't the most up to date - you can see at http://search.maven.org/#search%7Cgav%7C1%7Cg%3A%22com.google.cloud%22%20AND%20a%3A%22google-cloud-pubsub%22 and https://repo1.maven.org/maven2/com/google/cloud/google-cloud-pubsub/ that 0.20.0-beta is available.

Are you using some kind of proxy for Maven? io.grpc:grpc-core:1.2.0 is definitely available:

http://search.maven.org/#artifactdetails%7Cio.grpc%7Cgrpc-core%7C1.2.0%7Cjar

[NicolaSpreafico]

About the Maven repository, I'm currently using Eclipse Neon.3, which is configured by default like this

I'm used to use mvnrepository.com website only to get the pom.xml dependency snippet, once I configured it the download of the repository will be made from Eclipse, so from repo.maven.apache.org repository.

Even in this repository the grpc dependency is available https://repo.maven.apache.org/maven2/io/grpc/grpc-core/1.2.0/ so I'm wondering why of this error.

I tried to update/rebuild Index from Eclipse but I'm getting the same error
Description Resource Path Location Type
No versions available for io.grpc:grpc-core:jar:[1.2.0] within specified range

org.eclipse.aether.resolution.VersionRangeResolutionException: No versions available for io.grpc:grpc-core:jar:[1.2.0] within specified range

Also tried forcing the other repo with pom.xml, but no changes

<repositories>
    <repository>
        <id>central</id>
        <name>Maven Repository Switchboard</name>
        <layout>default</layout>
        <url>http://repo1.maven.org/maven2</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

The strange thing here is that the jar is downloaded inside the file-system, so the error cause maybe another one. The download of the file itself is not the cause.

Are you using some kind of proxy for Maven?

No proxy of any kind, direct connection from Eclipse

[briandealwis]

It's those pesky .lastUpdated files. They'll appear if you had a refused connection previously. You can force Maven to re-try with mvn -U, and with Maven > Update Project… > Force Update of Snapshots/Releases in m2eclipse.

[NicolaSpreafico]

Thank you,
the -U flag worked.

At the end I'm unable to use this lib already because of this note

https://github.com/GoogleCloudPlatform/google-cloud-java/tree/master/google-cloud-pubsub

google-cloud-pubsub uses gRPC as transport layer, which is not (yet) supported by App Engine Standard.

The main issue has been solved anyway.

[michaelbausor]

Since the main issue is resolved, I'm closing this out - please feel free to reopen if you have additional questions. Thanks!
