Talend Administration Center allows you to Publish your Jobs to a Nexus repository via the Publisher page.
From this page, you can:
create a publishing task on a Job or on all the Jobs designed in the Studio and set a threshold (percentage) of maximum failed tests allowed for these Jobs:
add a time-based trigger to publish the task to the selected Nexus repository, or publish it manually from the top toolbar:
check the publication status (here, the publication went well which means no tests failed):
For more information on publishing tasks and triggers, see the Talend Administration Center User Guide.
