Fetcher build failing to run with error: The directory name is invalid.

Hi Team,

We have requirement to create mtar by downloading few jars from maven repositories, so we are trying to use below fetcher option. But it is failing with error:

ERROR could not build the "my_module" module: could not execute the "mvn -B dependency:copy -Dartifact=mygroup:myart:1.0.0:war -DoutputDirectory=./target" command: fork/exec C:\x7z\apache_maven_3_9_5\bin\mvn.cmd: The directory name is invalid.

- name: my_module
build-parameters:
builder: fetcher
fetcher-opts:
repo-type: maven
repo-coordinates: mygroup:myart:1.0.0

Note: running "mvn -B dependency:copy -Dartifact=mygroup:myart:1.0.0:war -DoutputDirectory=./target" directly works fine. But on running through mbt build, it is failing.

Please let us know how it can be resolved.
Thanks,
Manoj.
