On windows, I am trying to install Maven by following the instructions from here. The step that states "Add the bin directory of the created directory apache-maven-3.3.9 to the PATH environment variable" is not making much sense to me. Could someone that has successfully installed Maven please explain what this step involves. I have already set the JAVA_HOME environment variable.
In the link you provided, there are more clear instructions:
Adding to PATH: Add the unpacked distribution’s bin directory to your user PATH nvironment variable by opening up the system properties (WinKey + Pause), selecting the “Advanced” tab, and the “Environment Variables” button, then adding or selecting the PATH variable in the user variables with the value C:\Program Files\apache-maven-3.3.9\bin. The same dialog can be used to set JAVA_HOME to the location of your JDK, e.g. C:\Program Files\Java\jdk1.7.0_51
Open a new command prompt (Winkey + R then type cmd) and run mvn -v to verify the installation.
Did you try this?
