Can you provide more information about your dependencies (perhaps provide your pom.xml/ build.gradle file)? Running this locally for me works.

try (CloudTasksClient cloudTasksClient = CloudTasksClient.create()) { QueueName name = QueueName.of("[PROJECT]", "[LOCATION]", "[QUEUE]"); Queue response = cloudTasksClient.getQueue(name); }

with this as well its not working

RYenike avatar May 28 '24 15:05 RYenike

There error is most likely due to how we resolve the endpoint. I see your dependencies are a bit old and it is probably due to a combo of old client library + new runtime library and the is unable to determine the endpoint. Can you try and change your pom.xml to use the latest libraries-bom and let us know if that works?

i.e.

<dependencyManagement>
   <dependencies>
   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.39.0</version> <!-- Latest libraries bom version -->
      <type>pom</type>
      <scope>import</scope>
   </dependency>
   </dependencies>
</dependencyManagement>

<dependencies>
   <dependency>
      <groupId>org.java-websocket</groupId>
      <artifactId>Java-WebSocket</artifactId>
      <version>1.5.0</version>
   </dependency>
   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-pubsub</artifactId>  <!-- Version is managed by libraries-bom above -->
   </dependency>
   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-storage</artifactId> <!-- Version is managed by libraries-bom above -->
   </dependency>
   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-bigquery</artifactId> <!-- Version is managed by libraries-bom above -->
   </dependency>
   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-tasks</artifactId> <!-- Version is managed by libraries-bom above -->
   </dependency>
</dependencies>

You're declaring it in the <dependencies> section. You need to declare the <dependencyManagement> section.

Additionally, you are also specifying the versions and not letting the bom set the versions for you: i.e.

   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-tasks</artifactId>
      <version>2.42.0</version>
   </dependency>

It should be

   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>google-cloud-tasks</artifactId>
   </dependency>

once you add in the bom
