Creating a custom component using Talend Component Kit 1.62.1 and Online does not work

Sven957 — Fri, 02 Jan 2026 14:45:42 GMT

Dear community,

I wanted to start developing custom components. But I keep running into issue already when trying to create a project.

Neither the online platform nor the intellij plugin in (1.62.1) seem to work.

The online starter at starter-toolkit.talend.io

Returns a 500 code when trying to create a ZIP export. Trying to create via github does not work either.

The intellij plugin runs into multiple exceptions rooting in a "MustacheException".

One example:

com.github.mustachejava.MustacheException: Failed to get value for value.key

I do have Oracle Open JDK 1.8 u391 installed and selected for the project in intellij. But quite frankly, I dont understand why I have to use it when Talend 8.0.1 runs on Java 11 and is currently implementing Java 17 support.

I would like to understand why both approaches fail and how I can start working on my first TCK project.

Cheers,

Sven

Hello,

You can find the open source TCK components here:

https://github.com/Talend/connectors-se

Could you please see if you're able to compile these?

Meanwhile I let the team know that the zip download from the starter-toolkit doesn't work.

Hi,

Thanks for the response and taking care of the zip download.

To your question:

I am able to compile a couple of those components. I tested: couchbase, newjdbc, salesforce.

For some I run into compile errors jira for instance.

Also the question again: Why do I have to choose the Oracle JDK 1.8?

Hello,

I'm facing the same error of "com.github.mustachejava.MustacheException: Failed to get value for value.key"" when trying to create the projet with TCK in intellij. I have tried several times but always the same problem.

Have you resolved the problem please ?

Thanks

Hello,

This is a bug that should be fixed on next release 1.63.0 (should be released next week).

Meanwhile, you can follow tutorial on our framework documentation

https://talend.github.io/component-runtime/main/latest/tutorial-create-an-input-component.html

(a sample pom.xml is shown) Or inspire you with our OSS connectors here : https://github.com/Talend/connectors-se

Best regards

Hello everybody,

I can confirm. Neither the ZIP download works nor the intellij Plugin.

This is very frustrating and quite disappointing.

@Talend do you have an estimate when this will be fixed eventually?
