I did get this error message in intellij while running a spring-boot server:

```
'mvn' is not recognized as an internal or external command, operable program or batch file

```

It didnt recognize maven when I was trying to build the project standing in my projectfolder with:
mvn spring-boot:run

I solved this by downloading maven: <https://maven.apache.org/install.html>
and manually added the bin file in the apache-maven-3.5.3 folder to librarys 

It seems a bit backwards. Are there any other/better way?
