Fixing Java Issue with German Umlauts
|
||||
*************************************
|
||||
With one of the last changes I faced the following error:
|
||||
|
||||

|
||||
All of a sudden this error popped up. I had absolutely no clue why suddenly this happened and I needed to search in the
|
||||
web for a hint. **NOTE:** The funny thing is that the job passed successfully once before the error popped up.
|
||||
|
||||
After searching for a reason I found something about german umlauts (ä,ö,ü) in a yaml file causing/same a similar issue.
|
||||
In the job updating the source revisions I had to configure the git user and my name holds a umlaut. This was not an
|
||||
issue until the nightly pipeline triggered this update job...
|
||||
After escaping the german umlaut the job ran again even in downstream mode, see an abstract of the diff here:
|
||||
|
||||
.. code-block::
|
||||
|
||||
- git config --global user.name "Marc Mattmueller"
|
||||
+ git config --global user.name "Marc Mattm\u00fcller"
|
||||
|
||||
So, keep in mind about how to treat german umlauts.
|
||||
|
||||
|
||||
Using Job Artifacts
|
||||
*******************
|
||||
To create a pulle/merge request when updating the source revisions a branch is created and pushed. The nightly fails in
|
||||
such a case if we would run it on the original branch. Hence, it makes sense to provide the created branch to the
|
||||
downstream jobs. Using job artifacts are an easy way of bringing some structure and clearness into that already complex
|
||||
topic of CI/CD. The current NWL instance version 0.3.2 does not contain the copyArtifact plugin and thus we get this
|
||||
issue:
|
||||
|
||||
.. code-block::
|
||||
|
||||
java.lang.NoSuchMethodError: No such DSL method 'copyArtifacts' found among steps [ ...
|
||||
|
||||
Therefore we will rebuild the NWL instance again after adding the plugin, see the diff of the repository *build-docker*:
|
||||
|
||||
.. code-block::
|
||||
|
||||
