mvnw.cmd for demo spring-boot project not working in windows

Question

I generated a simple demo project (2.3.0 version) from Spring Initializr to my windows 8.1 OS and below is the basic structure

C:.
└───src
    ├───main
    │   ├───java
    │   │   └───com
    │   │       └───example
    │   │           └───demo
    │   └───resources
    └───test
        └───java
            └───com
                └───example
                    └───demo

I tried running mvnw.cmd clean and getting bellow error:

C:\Users\Downloads\demo\demo>mvnw.cmd clean
"}" was unexpected at this time.

Below is the same output in powershell

PS C:\Users\Downloads\demo\demo> .\mvnw.cmd clean
"}" was unexpected at this time.
PS C:\Users\Downloads\demo\demo>

I see the issue is occurring in following lines within mvnw.cmd file :

powershell -Command "&{"^
    "$webclient = new-object System.Net.WebClient;"^
    "if (-not ([string]::IsNullOrEmpty('%MVNW_USERNAME%') -and [string]::IsNullOrEmpty('%MVNW_PASSWORD%'))) {"^
    "$webclient.Credentials = new-object System.Net.NetworkCredential('%MVNW_USERNAME%', '%MVNW_PASSWORD%');"^
    "}"^
    "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; $webclient.DownloadFile('%DOWNLOAD_URL%', '%WRAPPER_JAR%')"^
    "}"

Not sure if i am missing anything.

Did you run this in `cmd` or `powershell`? Try to run it in powershell — Sanjay Sharma, May 26 '20 at 18:21

@ValentinDespa Not yet but strangely i see this issue only on my machine. I did try the same in another machine and worked fine. — Sachin, Jun 25 '20 at 06:13
I have this error only in the Jenkins workspace folder. I have opened a bug report here: https://issues.apache.org/jira/projects/MWRAPPER/issues/MWRAPPER-4 — Valentin Despa, Jun 26 '20 at 16:08

I've just had the same problem, error in both cmd and powershell. Simply copying the project to an alternative directory solved the problem.

Im on windows 10, the project was originally in my downloads directory. I moved this into documents.

Testes and i worked on this path: C:\tmp\New (2){6} folder\my-app57(2). The problem is the ')' character.

My solution is:

@setlocal EnableDelayedExpansion
    powershell -Command "&{"^
          "$webclient = new-object System.Net.WebClient;"^
          "if (-not ([string]::IsNullOrEmpty('%MVNW_USERNAME%') -and [string]::IsNullOrEmpty('%MVNW_PASSWORD%'))) {"^
          "$webclient.Credentials = new-object System.Net.NetworkCredential('%MVNW_USERNAME%', '%MVNW_PASSWORD%');"^
          "}"^
          "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; $webclient.DownloadFile('%DOWNLOAD_URL%', '!WRAPPER_JAR!')"^
          "}"
@endlocal
