Modifying context parameters for specific tasks in Talend Administration Center

[Abdelrhman_Mohamed]

Are there any differences between modifying context parameters for a Normal or Artifact tasks in Job Conductor in TAC?
In another words, does any one of them hold an advantage in terms of modifying context parameters?

Helllo,

A normal task from nexus repository is like when you download the Job zip file in local and then add it as an archive file into your TAC, which doesn't maintain the links/references between Talend Administration Center and Nexus (one time download).

An artifact task from nexus repository will check the Job references between Talend Administration Center and Nexus at execution time and then download the newest job.

When you select an artifact task, the Job has a reference to Nexus. For example, you select the latest version of say, 0.3, of the Job in Version while adding a task. Then you change the Job in Studio and publish it with a new version of say, 0.4. The artifact task downloads the latest version, that is 0.4, before running it in the JobServer, since it has a reference to the Nexus. However, a similar Job selected through the normal task (select artifact from Nexus repository), still uses 0.3, because it don't have a reference to Nexus.

Hello,  

Thanks for the quick support.  

I appreciate the clarification on the difference between the Normal and Artifact Task. However, does this mean that if I change the context parameters in the Artifact Task, they will change again when I publish a new version of the Job, or will they stay the same regardless of how many versions I publish for the same Job?  

For the Normal Task, from what I understand, it’s a one-time upload to TAC, so the context parameters shouldn’t change if I add a new version of the same Job, correct?

for an Artifact task, the context values are tied to the task configuration, not automatically replaced every time you publish a new job version
