CLI Deploy Error Could not find or load main class org.eclipse.core.launcher.Main

Anonymous — Sat, 16 Nov 2024 06:31:05 GMT

Hi there,

I´m struggling at the moment with CI/CD stuff with Talend 7.1.

I have installed TAC 7.1, Nexus 3, Maven, GIT and Jenkins... Now I was working with this documentation as Talend CommandLine is deprecated up from 7.1.

Now i have configured one Jenkins Maven Deploy job with following settings:

TALEND_POC/poms/pom.xml

deploy -X -fae -amd

-Dgeneration.type=local
-Dproduct.path=/talend/Talend-Studio-20181026_1147-V7.1.1/configuration/.m2/repository
-Xmx3076m
-DaltDeploymentRepository=talend-custom-libs-release::default::http://SERVER:8081/repository/talend-custom-libs-release/
-Dproject.distributionManagement.repository.url=http://SERVER:8081/repository/talend-custom-libs-release/
-Dproject.distributionManagement.repository.id=talend-custom-libs-release

After Run and Downloading all packages i get this Error: (Job Console)

I have already delete the workspace and checked java and some dependencies but it dont work.

It seems like the studio has not this dependency "org.eclipse.core.launcher"?!

Hello

Please try the product.path to the Studio (<commadline_home>/Studio) in your jenkins job. It should work.

in your case may be -Dproduct.path=/talend/Talend-Studio-20181026_1147-V7.1.1

Oh perfect... this works..

Scripts are going forward now.. But I think I have the last problem until the process is finished.

My test-job is separated into a parent-job which call a child-job with tRunJob.

In child-job is a System.out.print only.

Deployment now got failure on childjob. Parent-Job is running perfectly:

Can´t reach maven goal deploy:

Error is:

talend_poc.c_import_cars_0_1 cannot be resolved to a type

and at the end:

Failed to transfer file http://inhas66913:8081/repository/releases/org/example/talend_poc/job/c_import_cars/0.1.0/c_import_cars-0.1.0.jar with status code 400 -> [Help 2]

Anyone an idea why parent-job runs without errors and child-job with a simple System.out.print in an tJava fails?

There are two errors which I see one related to resolution and other for Nexus. For resolution error please check if you are able to execute the job in Studio itself.

First I believe its clear with the goal deploy maven is going to publish the artifact to Nexus (or artifactory). It does not mean that it is going to deploy the job on jobserver. There is no execution of the job involved here. So it does not matter what have you implemented in your child job.

The error you are facing seems to be due to usage of release artifact. I believe you are still developing so you should be using snapshots. The release artifact can not be overridden so you are facing this error. Once you reach a milestone in your project then you use release artifact.

P.S. May be you want to create another thread as it would misleading from your original issue you started thsi thread for.

Hello,
I have similar issue; the dependency is missing "org.eclipse.core.launcher.Main".

I am using Talend 7.1.1 and trying to build the job in jenkins.
Some logs:

One point I don't understand, do we need commandLine studio or CI Builder will takecare of it?

Thanks,
