zsh: command not found: mvn

zsh: command not found: mvn means Maven's bin directory is not on the current PATH. Check Java and the command separately:

java --version
command -v mvn

For an existing Maven installation, add its bin directory using the setup instructions for your operating system, reload zsh, and verify:

source ~/.zshrc
mvn --version

Many projects include the Maven Wrapper. In that case you do not need a global Maven installation:

./mvnw test       # macOS/Linux
./mvnw.cmd test   # Windows

The wrapper still needs a compatible Java runtime. Do not “fix” the error by placing a random Maven directory in PATH; check MAVEN_HOME, the project README, and the official Maven installation page. If a command works in one terminal but not another, compare shell startup files and the value of PATH rather than reinstalling the project.
