Passing a context file from command line

Anonymous — Mon, 20 Aug 2018 16:43:16 GMT

Hello everyone,

I found a lot of threads about this problem but none helps me.

I try to execute a job from the command line by passing the following command (I need to execute job with two different contexts):

myJob.bat --context=myContext

The problem is such as myContext needs to be in a specific folder of the job folder. However, I need my context in an other place. So I should pass the path of the context file in the context parameter like:

myJob.bat --context=path/myContext

But it seems to not work, I got an error message 'Could not find the context myContext'.

I tried with simple cotes and doubles cotes but it didn't change anything.

How to pass this kind of parameter, a context file with a specific path?

Or, how to change the default folder where the context files need to be there?

Here is the tree view to help understanding the need:

jobFolder
- myJob (the .bat file)
- project (folder generated by Talend when building the job)
  - job
    - contexts
      - Context files that I can pass (so I should copy my context files there but I need them in an other folder)
customizedContexts
- myContext (the context file that I want to pass, but I don't know how to pass the path to this file)

Thank you for your help,

Kevin

I believe passing passing --context=myContext might only pass the name of the context env ex. Dev, Prod, ... but cannot externalize the location of a context file.

try using a tFileInputDelimited-> tContextLoad to externalize the context file. See the doc of tContextLoad

I created two tFileInputDelimited-> tContextLoad units in my job, that correspond to my two contexts.

How to pass the context that I want to use when I execute the job from the command line? I seen something like --context_parameter but it didn't works for me.

Or do I need to have only one tFileInputDelimited-> tContextLoad unit, and a .properties file that contains my two environments? In this case, how to choose which one environment I want to use when I pass the context form the command line?

Thanks,

Kevin
