PowerShell get or stop a particular Java process

Question

I am using PowerShell script to start multiple Java application.

$app = Start-Process -FilePath java -ArgumentList "-jar $path_to_jar" -PassThru

it's working as expected.

But I also have to search a particular Java process and stope/close it.
I cant use process id ($app.ID) as stop script will be a different script.

Can I have some custom name/identifier to these Java process to get a particular process ? like if I can fetch a java process by JAR name etc.

Not sure but in Linux environment I have seen use of -DAPP_INSTANCE_NAME flag , that might be a custom flag to identify a process.

Any help is apricated.

Why not store the PID and any descriptive information in a log file that can be parsed by your stop script? — thepip3r, Feb 01 '22 at 16:38
@thepip3r - that's one option. probably the last option if nothing comes out. — Posto, Feb 01 '22 at 17:08

Finally I am using JPS , it's command

& jps -v

returning all the details like jar name etc. and that result I am using for filtering out the process id.

leave a snippet here

Get-Process -Id ((jps) | Select-String -Pattern '([0-9]+)\s+foo\.jar').Matches.Groups[1].Value | Stop-Process

if you not sure if this process exist

(jps).where({$_ -match '^([0-9]+)\s+foo\.jar'})
# add check here
Get-Process -Id $Matches.1 | Stop-Process

Note for Windows user : On my computer , Get-WmiObject -Query ...(wmic in powershell) sometimes return empty CommandLine property. And this jps way works fine.
