I am trying to create a Google Cloud Function using the Java Client API with this client:
Credentials myCredentials = ServiceAccountCredentials.fromStream(new FileInputStream(keyFile));
CloudFunctionsServiceSettings settings = CloudFunctionsServiceSettings.newBuilder()
.setCredentialsProvider(FixedCredentialsProvider.create(myCredentials)).build();
client = CloudFunctionsServiceClient.create(settings);
String project = "my-project-name";
String location = "us-central1";
LocationName locationName = LocationName.of( project, location );
CloudFunction function = CloudFunction.newBuilder().build();
CloudFunction response = client.createFunctionAsync(locationName, function).get();
I tried different invocations but I'am getting always the following stack trace:

Does anyone know what do i wrong ?
Thank you
The error means that your Function Builder is missing the required parameters in order to create the function. If you try to create a function via Cloud Console, you're required to enter details such as function name, entrypoint, runtime, trigger type, and source code.
I've already reached out to the engineers and they are now informed with regards to the lack of details in the log output.
As a solution, here's a sample code that will create a Cloud Function running on Java 11. Of course you can always choose any type of runtime you want:
package function;
import com.google.cloud.functions.v1.CloudFunctionsServiceClient;
import com.google.cloud.functions.v1.HttpsTrigger;
import com.google.cloud.functions.v1.CloudFunction;
import com.google.cloud.functions.v1.LocationName;
public class App {
public static void main( String[] args ){
try {
// TODO: Add your credentials here
CloudFunctionsServiceClient cloudFunctionsServiceClient = CloudFunctionsServiceClient.create();
String location = LocationName.of("[PROJECT_ID]", "us-central1").toString();
CloudFunction function = CloudFunction.newBuilder()
.setName(location + "/functions/[FUNCTION_NAME]")
.setEntryPoint("functions.HelloHttp") // fully qualified class name (FQN)
.setRuntime("java11")
.setHttpsTrigger(HttpsTrigger.getDefaultInstance())
.setSourceArchiveUrl("gs://[BUCKET_NAME]/source_code.zip")
.build();
CloudFunction response = cloudFunctionsServiceClient.createFunctionAsync(location, function).get();
}catch (Exception e){
e.printStackTrace();
}
}
}
Note: If your zipped source code is from a storage bucket, make sure your source files are at the root of the ZIP file, rather than a folder containing the files.

I wasted hours trying the Google Document AI java example from https://cloud.google.com/document-ai/docs/quickstart-client-libraries
If you enter your for projectId, location and processorId like this
String projectId = "6493xxxxxxxx";
String location = "eu";
String processorId = "74451xxxxxx";
String filePath = "/Users/schube/Desktop/file.pdf";
and run the example, you just get an InvalidArgumentException:

That is really great, because which f*** element is invalid? There are no details in the exception and there is no logfile.
So, turns out after reading this: What argument is invalid for Google Document AI client library for Node js?
that if the location is not "us" but "eu", you have to specify an other endpoint.
Oh man, why did they not mention that in the tutorial or the source code? It just says:
// TODO(developer): Replace these variables before running the sample.
String projectId = "your-project-id";
String location = "your-project-location"; // Format is "us" or "eu".
String processorId = "your-processor-id";
String filePath = "path/to/input/file.pdf";
The really should have mentioned that it is not enough to switch to "eu".
So the simple solution is, do not use
try (DocumentProcessorServiceClient client = DocumentProcessorServiceClient.create()) {
but
try (DocumentProcessorServiceClient client = DocumentProcessorServiceClient.create(
DocumentProcessorServiceSettings.newBuilder().setEndpoint("eu-documentai.googleapis.com:443").build())) {
I'm trying to implement code that uses the Azure Java SDK to list the SQL Server instances running on my Azure subscription.
I followed the examples posted and wrote the following code:
Azure azure = Azure.authenticate(credentials)).withDefaultSubscription();
SqlServers sqlServers = azure.sqlServers();
PagedList<SqlServer> list = sqlServers.list();
But the last line throws a java.lang.NoSuchMethodError with the following stack trace:

This obviously looks like a defect as the SDK allows to do that and should return a reasonable error code if something goes wrong.
Still, is there any other way to list the SQL Server instances running in my Azure subscription? Or perhaps I'm doing something in my code?
Please refer to my working code as below:
import com.microsoft.azure.AzureEnvironment;
import com.microsoft.azure.PagedList;
import com.microsoft.azure.credentials.ApplicationTokenCredentials;
import com.microsoft.azure.management.Azure;
import com.microsoft.azure.management.sql.SqlServer;
import com.microsoft.azure.management.sql.SqlServers;
import java.io.IOException;
public class ListSqlInstance {
public static void main(String[] args) throws IOException {
ApplicationTokenCredentials credentials = new ApplicationTokenCredentials(
"{client Id}",
"{talent Id}",
"{secret}",
AzureEnvironment.AZURE);
Azure.Authenticated azureAuth = Azure.authenticate(credentials);
Azure azure = azureAuth.withDefaultSubscription();
SqlServers sqlServers = azure.sqlServers();
PagedList<SqlServer> list = sqlServers.list();
System.out.println(list.size());
}
}
My sdk version:
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure</artifactId>
version>1.12.0</version>
</dependency>
Don't forget grant access sql server permissons to your client.
Hope it helps you.
I am not sure if you are looking for a powershell cmdlet solution. But this Powershell cmdlet should list all the sql server instances in your subscription.
Assuming prior to running this powershell cmdlet you already logged in to your azure account in powershell and set the current subscription in the current powershell session if you have multiple subscriptions mapped to your account.
PS C:\azure> get-azurermresourcegroup | get-azurermsqlserver
ResourceGroupName : DbRG
ServerName : testSqlserver
Location : East US
SqlAdministratorLogin : XXXX
SqlAdministratorPassword : XXX
ServerVersion : 12.0

Problem solved!
The error came from an incompatibility between the Azure SDK and the jackson-databind library.
One of the methods used from this library is relatively new, and the version I had in my project (clean project with just one import - Azure SDK) did not have this method.
Imported the latest jackson-databind as follows:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.5</version>
</dependency>
Has solved the problem.
Thanks Everyone for the help.
I've been trying to get the Google Pub/Sub Java libraries to work using the Quickstart guides. None of them work as written, at least not for me. I'm working in IntelliJ, Maven framework, OSX, Java 8.
Take this example. I followed all the steps: Created a service account as Project Owner, installed the Gcloud SDK, set my GOOGLE_APPLICATIONS_CREDENTIALS envvar, and found that everything was hunky dory from the command line: I could create topics, publish messages, whatever I wanted.
Then when I tried to run the sample code:
import com.google.api.gax.rpc.ApiException;
import com.google.cloud.ServiceOptions;
import com.google.cloud.pubsub.v1.TopicAdminClient;
import com.google.pubsub.v1.ProjectTopicName;
public class CreateTopicExample {
/**
* Create a topic.
*
* #param args topicId
* #throws Exception exception thrown if operation is unsuccessful
*/
public static void main(String... args) throws Exception {
// Your Google Cloud Platform project ID
String projectId = ServiceOptions.getDefaultProjectId();
// Your topic ID, eg. "my-topic"
String topicId = args[0];
// Create a new topic
ProjectTopicName topic = ProjectTopicName.of(projectId, topicId);
try (TopicAdminClient topicAdminClient = TopicAdminClient.create()) {
topicAdminClient.createTopic(topic);
} catch (ApiException e) {
// example : code = ALREADY_EXISTS(409) implies topic already exists
System.out.print(e.getStatusCode().getCode());
System.out.print(e.isRetryable());
}
System.out.printf("Topic %s:%s created.\n", topic.getProject(), topic.getTopic());
}
}
It throws the ApiException PERMISSION_DENIED. The full stacktrace:

The debugger tells me the projectId is set for the correct default project for that service account, so the service account is connected. And, as I said, I verified from the console that the permissions are in fact set to Project:Owner for that service account. So ... why the permission denied?
Thanks in advance for reading gnarly stack traces on my behalf.
Since you are running with no problem with gcloud this must be a problem with IntelliJ. You should check whether you need to start IntelliJ via shell (as described in this article) or set the GOOGLE_APPLICATIONS_CREDENTIALS variable in IntelliJ as described here.
I'm using CUPS4J for my project, which depends on http-client, http-core, and slf4j.
To resolve dependencies we use Maven, and I have defined dependencies as follows:
<dependency>
<groupId>cups4j</groupId>
<artifactId>cups4j</artifactId>
<version>0.6.4</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.0.3</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>

<version>4.1</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.7</version>
</dependency>
The cups4j dependency is on our ArtiFactory server (I couldn't find it online).
Everything works like a charm if I create a sample main method to print some document and launch it as a java application.
When I publish my classes to the Websphere server and call that method from a webpage, it generates a java.lang.LinkageError.

It seems that HttpUriRequest already exists and makes conflict with the one provided by the httpclient library from Apache, but if I try removing that dependency from pom.xml, I get a NoClassDefFoundException for that class.
If it matters, my IDE is Eclipse Luna.
How can I solve this exception?
WebSphere uses also httpclient library which may conflict with one you are providing.
Try to create isolated shared library in admin console via Environment > Shared Libraries. Put http-*, slf4j and cups4j jars there and associate that shared library with your application.
I have some code for connecting to a JClouds swift storage container which works fine in its own test area, but once I integrate into my project, I get an error:
Exception in thread "main" java.util.ServiceConfigurationError:
org.jclouds.apis.ApiMetadata: Provider
org.jclouds.openstack.keystone.v2_0.KeystoneApiMetadata could not be
instantiated: java.lang.IllegalStateException:
java.lang.reflect.InvocationTargetException
This is the code which fails on the ContextBuilder line:
private SwiftApi swiftApi;
public JCloudsConnector(String username, String password, String endpoint) {
String provider = "openstack-swift";
Properties overrides = new Properties();
overrides.setProperty("jclouds.mpu.parallel.degree", "" + Runtime.getRuntime().availableProcessors());
swiftApi = ContextBuilder.newBuilder(provider)
.endpoint(endpoint)
.credentials(username, password)
.overrides(overrides)
.buildApi(SwiftApi.class);
}
I am using the same dependencies (JClouds version 1.7.3) so I can't understand what the problem might be since both are run in the same environment.
