I think your database user name and password are not corrrect. looking at this log line:

2022-10-05 23:35:11.174 [main] INFO net.corda.libs.configuration.validation.impl.ConfigurationValidatorImpl - Configuration to validate: {“crypto”:{“hsmId”:“SOFT”},“db”:{“params”:{“database”:{“jdbc”:{“directory”:“C:\Users\ashwani.kumar02/.corda/corda5/jdbcDrivers”,“url”:“jdbc:postgresql://localhost:5432/cordacluster”},“pass”:“password”,“user”:“user”}}},“dir”:{“tmp”:“C:\Users\ASHWAN~1.KUM\AppData\Local\Temp\/corda/tmp”,“workspace”:“C:\Users\ASHWAN~1.KUM\AppData\Local\Temp\/corda/workspace”},“instanceId”:0,“kafka”:{“common”:{“bus”:{“busType”:“DATABASE”}}},“topicPrefix”:“”}

This is the line we use to start the postgres container in startCorda gradle helper

        new ProcessBuilder(
                "docker",
                "run", "-d", "--rm",
                "-p", "5432:5432",
                "--name", dbContainerName,
                "-e", "POSTGRES_DB=cordacluster",
                "-e", "POSTGRES_USER=postgres",
                "-e", "POSTGRES_PASSWORD=password",
                "postgres:latest").start();

Try changing your configuration to use the above user name and password.

Could you post the command you used to start your postgres instance.

Yes, I am using Java 11 (OpenJDK Version 11.0.13) and following is the output

PS C:\Projects\R3\Corda 5\cordapps\CSDE-cordapp-template-kotlin> ./gradlew build

I do have a docker hub account and I noticed that I haven’t signed in so just to avoid any confusion, I did sign in as well.

Thanks for confirming on Point 3, I have removed those folders as part of DP2 setup

I did follow the steps for reset-csde and then executed the startCorda task and found below error in logs. (I was denied file upload being a new user so have to copy the logs here.)

The other thing that I noticed that postgres container didn’t come up, am on windows machine and I have seen couple of threads where postgres docker image does give issue on windows. Tried couple of things to run postgres image in isolation just to see if that container is coming up by defining a volume and then attaching the volume when I am trying to bring up the container. Also, I changed the option to ‘Switch to Linux Containers’ in docker desktop but nothing worked out.

On point 1 – can you try to build using ./gradlew build and post the error messages here.

(Also, make sure you are using Java 11, not 8)

[QA Bot]

To add on point 2: You have to wait a while after the startCorda task shows as complete before the cluster is ready to accept http calls. You can test if the cluster is up and running by clicking the listVNodes task, if it’s running it will complete successfully, but show no nodes. If the cluster is not up yet it will throw an Connection refused (Connection refused) error. Keep poling it every 10 seconds or so and it should come up in around a minute.

If its not working, follow the reseting CSDE instructions shown here: reset-csde and try again.

[QA Bot]

Regarding points 2 & 3

2. The startCorda task should start a Postgresql container.
   Some reasons why the postgres container failed to start include

• the Docker daemon not completing start up
• not having access the to the docker hub repository.

3. corda-node-cli and cordapp-builder are not required for Corda 5 DP2

[QA Bot]

I have just followed the steps for setting up Corda 5 DP2, here is my feedback particularly around the ease of setting up the environment and make it up and running

1. After following all the steps, pre requisite installation, corda-cli installation, csde setup
   First thing, when I opened up MyFirstFlow.kt for all corda classes which are being used in first flow it was showing Unresolved reference even after all dev preview classes were there in intellij project external libraries
2. I did buildCPI task it was showing success, then I did startCorda it was showing success but when I tried to access the swagger it didn’t open up I checked the corda.log in logs folder, found that it was showing connection refused error for postgres and I was assuming the startCorda might spin off postgres container but didn’t see that either in docker desktop
3. One another thing that I wanted to ask was as part of DP1, we were asked to install corda-node-cli and cordapp-builder however I didn’t see any mention of them in DP2 so I removed them from .corda folder

[QA Bot]

SOLVED!

Make sure your IntelliJ global gradle setting is set to use the project’s sdk settings rather than picking up whatever the machine’s globally set JDK is

[QA Bot]

In that case, you can simply delete the empty json file, the gradle task will generate a new one.

I suspect that this might be caused by a previous compilation failure, that generated the json file, but never populate it with content.

[QA Bot]

Okay… I checked the code and saw in the createGroupPolicy task, it creates a json file. And mine is empty.

[QA Bot]

In each of the tasks that are executing, we had put in the logging messages. It looks like that a group policy is missing during the compilation.

[QA Bot]

Yes, there are a few steps you do need to complete before trying out the CSDE template. Please follow the Corda CLI installation guide here
