How to execute maven test in a (unix/git) bash in intellij on windows?

This is not an exact answer to my question, but to share the solution I setup for my specific problem of executing python test through maven:

First, I use the exec-maven-plugin for maven to exec python unitest in the test step. However, it works whan called from git-bash (and probably any linux shell) with python intalled, but as explained in my question above, it fails when executed though intellij because it uses a windows shell.

So, what can be done is to use as sh.bat file to call the python unitest command with a unix shell and put "sh" in the 'executable' part of maven exec plugin configuration: in unix, it call the 'sh' command, and on windows system it calls the sh.bat file

in the pom

 <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>3.0.0</version>
    <executions>
      <execution>
        <id>run-python-test</id>
        <phase>test</phase>
        <goals>
          <goal>exec</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <executable>sh</executable>
      <arguments>
        <argument>-c</argument>
        <argument>python -m unittest discover src/test/</argument>
      </arguments>
    </configuration>
  </plugin>

And create a sh.bat file with something like (here I call sh.exe from a git install on windows)

"C:\Program Files\Git\bin\sh.exe" %*

Notes:

• I found the idea from https://stackoverflow.com/a/46410022/1206998
• The sh.bat file is maybe avoidable if sh.exe is in the (windows) path
• Adapt the python -m unittest discover src/test/ argument to the test structure your are using. Here I put the tests in src/test and thus I need a __init__.py file that add src/main/python where the prod code is to the system path. See https://stackoverflow.com/a/59732673/1206998
