Guillaume Nodet commented on MNG-8608:
--------------------------------------
Can the IDE use the `jps` command and inspect them to check Maven processes ?
This could be implemented inside mvnsh as a command.
> Provide a way to find running maven processes similar to jps command
> --------------------------------------------------------------------

> Key: MNG-8608
> URL: https://issues.apache.org/jira/browse/MNG-8608
> Project: Maven
> Issue Type: New Feature
> Reporter: Christoph Läubrich
> Priority: Major
>
> Java provides a [jps
> command|https://docs.oracle.com/en/java/javase/11/tools/jps.html] to list all
> running java processes.
> It would be useful to have such capability for maven as well, as an example I
> like to call:
> {code}mvn -ps{code}
> and get a list of maven processes running on the system, it should include:
> # the process id
> # the workdirectory
> # the session execution root directory
> # the maven version
> How this is achieved, could be platform specific like it is for jps, and it
> might not discover all maven processes but only those for the current user.
> *+Why is this useful needed:+*
> * Currently a maven build do not perform any way of locking so one can easily
> run two maven processes working on the same project tree
> * But due to how maven works this can only end in disaster (e.g. one process
> clean what the other has build) or at best result in some strange state if
> two maven processes run in parallel
> * Currently there is no way for an IDE to prevent interference with running
> maven processes that work on the same file tree
> Because of this maven should detect other processes running in the same
> file-tree and either wait or refuse execution.
