Re: Request to on how get "workspace" location from Run object - for workflow compatibilty

[Mads Nielsen]

You can get the Workspace from the run object by doing run.getExecutor().getCurrentWorkspace(). 

Since you're a build wrapper you have a footprint just after checkout of workspace....so you should have a workspace at that point in the run object.

Hello All,

I would like to get the workspace of the Run object. To make workflow compatible, my custom build wrapper class extends SimpleBuildWrapper.

I  had overridden the method :

public void setUp(Context context, Run<?, ?> run, FilePath workspace, Launcher launcher, TaskListener listener, EnvVars initialEnvironment)
            throws IOException, InterruptedException

But, how to get the workspace directory location from the Run object? (As I have to read some file within workspace)

I tried to typecast to AbstractBuild, but during build I got ClassCastException

java.lang.ClassCastException: org.jenkinsci.plugins.workflow.job.WorkflowRun cannot be cast to hudson.model.AbstractBuild

My Workflow code was: 

node{
wrap([$class: 'MyCustomBuildWrapper']) {
   print ('Hello')
}
}

Also, after workflow build is completed, will the workspace gets deleted? (As, I couldn't find the workspace folder in my Jenkins home (Also couldn't find Workspace Icon/link in Jenkins GUI) after the build completes)

Or will the workspace gets created only after SCM checkout?

Thanks

The point of SimpleBuildWrapper and similar other interfaces is that it tells you e.g. the relevant workspace as a parameter. This way your Workflow job/run can have any number of workspaces in parallel.

From Javadoc of Executor#getCurrentWorkspace():

> If current executable is AbstractBuild, return the workspace that this executor is using, or null if the build hasn't gotten to that point yet.

So that won't work for Workflow, which isn't based on AbstractBuild.

I.e. you have it right in front of you :)

public void setUp(Context context, Run<?, ?> run, FilePath workspace, Launcher launcher, TaskListener listener, EnvVars initialEnvironment)

Thank you all!! :) Is it valid to use the below to get the AbstractProject  or Project  or WorkFlowJob?

SubTask currentExecutable = run.getExecutor().getCurrentExecutable().getParent();

Thanks!

[Robert Sandell]

use run.getParent() instead.

Thank you! If ,config.jelly is not present for CustomBuildWrapper (extends SimpleBuildWrapper), the below exception is thrown for Workflow job . No exception if used via FreeStyleProject

CustomBuildWrapper doesn't have any GUI apart from the default one(one checkbox) provided by SimpleBuildWrapper (i guess it is from SimpleBuildWrapper).

The above exception occurs when Snippet Generator is used to get the groovy code. Any solutions?

Thank you!

Does not matter, it should still offer a `config.jelly`:

<?jelly escape-by-default='true'?>
<j:jelly xmlns:j="jelly:core"/>
