Could not Perform Maven Update

[kesavan22]

I recently created Jhipster app using generator version 8.7.3, while generating files noticed log Cannot start maven from wrapper. But the files were generated successfully i could see the execution completion log.

Is this anything wrong in my system wondering due to the space between my PC Username?

Please share your thoughts on this.

Thank you.

Below is the error occurred on performing maven update, i have checked the .m2 folder dependency was downloaded from central maven repo.

Adding some more observations

Created a new app with the older generator version 7.9.4. I could see the libraries downloading from central repo without error

Can you execute the wrapper directly via cli? Regarding the space, at least I rembemer some issues with spaces (in particular on windows) with node/npm we use to execute the task during generation.

No, I can't execute this via cli, but the downgraded version I can

This is an upstream issue:

• https://issues.apache.org/jira/projects/MWRAPPER/issues/MWRAPPER-151

Nothing to do in your side.

In my case, with Maven on Windows, I was also to fix the error by adding quotes around the %MVNW_CMD% in the generated mvnw.cmd.

I changed:
@IF NOT "%__MVNW_CMD__%"=="" (%__MVNW_CMD__% %*)
to:
@IF NOT "%__MVNW_CMD__%"=="" ("%__MVNW_CMD__%" %*)

Maybe this fix could be applied to the generator template (line 43) https://github.com/jhipster/generator-jhipster/blob/main/generators/maven/templates/mvnw.cmd
