In this post, we look at various tips that can be useful when automating R application testing and continuous integration, with regards to orchestrating parallelization, combining sources from multiple git. See Jenkins image documentation for reference. Jenkins: How to set the build-result as UNSTABLE when tests fail in a Declarative Pipeline 1 min read I have just spent a few weeks worth of time, creating Jenkinfiles for Declarative Pipelines for x-platform builds for two C++ projects. Jenkins declarative pipelines begin with a root pipeline block. Jenkins allows to specify pipelines using a Jenkinsfile. And we may want it to run regardless of whether the build succeeded (especially if we have it set up to link to the last successful build). An example with Scripted Pipeline is provided although it is also applicable to newer Declarative Pipeline with minor modifications. Save my name, email, and website in this browser for the next time I comment. The SAP Cloud SDK Cx Server is already configured to make the library available to pipeline-builds running inside it. Indeed nothing stops you from putting a parameters block in your pipeline script. For example, to propagate a path to a user library, an example Jenkinsfile could look as follows:. A possible pitfall: Inlining stage. This increases the chance that the background task has already finished, so no more waiting for the webhook. It makes the pipeline code easier to read and write. Existing object matching methods find one-to-one matching.
